During the COVID-19 pandemic we’re constantly being reminded to practise good hygiene by frequently washing our hands and regularly cleaning the spaces where we live and work.

These practices aim to remove or kill the coronavirus that causes COVID-19, and thereby minimise our risk of infection.

But there have been some suggestions using hand sanitiser and practising other hygiene measures too often could weaken our immune system, by reducing our body’s exposure to germs and with it the chance to “train” our immune defences.

The good news is, there’s no evidence to suggest this will be the case.

The ‘hygiene hypothesis’

For healthy immune function, it’s important we’re exposed to a diverse range of bugs in the environment, known as microbes. Most of these don’t make us sick.

The belief that a high level of cleaning and personal hygiene weakens our immune system is a common interpretation of what’s called the “hygiene hypothesis”.

The hygiene hypothesis is a theory that suggests a young child’s environment can be “too clean”, and they won’t be exposed to enough of these microbes to effectively stimulate their immune system as it develops.

The argument is that this results in increased allergies, asthma and certain autoimmune disorders. But scientists have refuted this hypothesis in recent years, as research has shown there are multiple other reasons for the increased incidence of these conditions.

Importantly, being too dirty doesn’t help our immune system either. It generally makes inflammation worse.

What is the immune system?

The immune system works to protect our bodies against things that threaten to make us sick — from harmful chemicals, to bacteria and viruses, to cancer cells.

It’s made up of two lines of defence. The first is the “innate” immune system, which responds rapidly to a range of pathogens to fight infection and prevent tissue damage.

Next is the “adaptive” immune system, made up of immune cells that develop a more targeted or specific response to fight off harsher germs such as viruses. Adaptive immune cells work by recognising small parts of the virus on the outside of the infected cell (for example, lung cells), and destroying them.

These cells then become what we call “memory cells”. The next time they encounter the same virus, they can eliminate it straight away.

This development of the immune system starts after birth and declines in old age.

What can weaken our immune system?

Some aspects of our modern lifestyle can weaken our immune system. These include:

But there’s no scientific evidence to support the notion that extra hygiene precautions will weaken our immune system or leave us more susceptible to infection by bacteria or viruses.

Microbes are everywhere: in the air, on food, and in plants, animals, soil and water. They can be found on just about every surface, including inside and outside your body.

The hygiene measures recommended during COVID-19 will help curb the spread of the coronavirus and greatly reduce our risk of infection — but won’t eliminate all microbes from our lives.

Keep it clean

Cleaning refers to the removal of microbes, dirt and impurities from surfaces. It doesn’t kill microbes, but by removing them, it lowers their numbers and therefore reduces the risk of spreading infection.

In contrast, disinfecting refers to using chemicals, known as disinfectants, to kill microbes on surfaces.

A combination of cleaning and disinfecting is the most effective way to get rid of microbes such as coronavirus.

Extra hand hygiene is of course one of the most important infection control measures.

We’ve been advised to clean our hands with soap and water for at least 20 seconds. If this is not possible, use hand sanitiser with at least 60% ethanol or 70% isopropanol.

Frequent hand-washing, especially if a sanitiser is used, can disrupt the natural skin biome, which can lead to increased skin infections. This can be managed with the use of moisturisers.

But the extra hygiene measures during COVID-19 won’t weaken our immune systems. On the contrary, they are vital in controlling the pandemic.

If you’re worried about your immune system, don’t stop washing your hands or keeping your house clean. Importantly, follow a healthy balanced diet, do regular exercise and look after your mental health.

Egyptian Couple Shot by Muslim Extremists Undaunted in Ministry


Left for dead, Christians offer to drop charges if allowed to construct church building.

CAIRO, Egypt, June 9 (CDN) — Rasha Samir was sure her husband, Ephraim Shehata, was dead.

He was covered with blood, had two bullets inside him and was lying facedown in the dust of a dirt road. Samir was lying on top of him doing her best to shelter him from the onslaught of approaching gunmen.

With arms outstretched, the men surrounded Samir and Shehata and pumped off round after round at the couple. Seconds before, Samir could hear her husband mumbling Bible verses. But one bullet had pierced his neck, and now he wasn’t moving. In a blind terror, Samir tried desperately to stop her panicked breathing and convincingly lie still, hoping the gunmen would go away.

Finally, the gunfire stopped and one of the men spoke. “Let’s go. They’re dead.”

 

‘Break the Hearts’

On the afternoon of Feb. 27, lay pastor Shehata and his wife Samir were ambushed on a desolate street by a group of Islamic gunmen outside the village of Teleda in Upper Egypt.

The attack was meant to “break the hearts of the Christians” in the area, Samir said.

The attackers shot Shehata twice, once in the stomach through the back, and once in the neck. They shot Samir in the arm. Both survived the attack, but Shehata is still in the midst of a difficult recovery. The shooters have since been arrested and are in jail awaiting trial. A trial cannot begin until Shehata has recovered enough to attend court proceedings.

Despite this trauma, being left with debilitating injuries, more than 85,000 Egyptian pounds (US$14,855) in medical bills and possible long-term unemployment, Shehata is willing to drop all criminal charges against his attackers – and avoid what could be a very embarrassing trial for the nation – if the government will stop blocking Shehata from constructing a church building.

Before Shehata was shot, one of the attackers pushed him off his motorcycle and told him he was going to teach him a lesson about “running around” or being an active Christian.

Because of his ministry, the 34-year-old Shehata, a Coptic Orthodox Christian, was arguably the most visible Christian in his community. When he wasn’t working as a lab technician or attending legal classes at a local college, he was going door-to-door among Christians to encourage them in any way he could. He also ran a community center and medical clinic out of a converted two-bedroom apartment. His main goal, he said, was to “help Christians be strong in their faith.”

The center, open now for five years, provided much-needed basic medical services for surrounding residents for free, irrespective of their religion. The center also provided sewing training and a worksite for Christian women so they could gain extra income. Before the center was open in its present location, he ran similar services out of a relative’s apartment.

“We teach them something that can help them with the future, and when they get married they can have some way to work and it will help them get money for their families,” Shehata said.

Additionally, the center was used to teach hygiene and sanitation basics to area residents, a vital service to a community that uses well water that is often polluted or full of diseases. Along with these services, Shehata and his wife ran several development projects, repairing the roofs of shelters for poor people, installing plumbing, toilets and electrical systems. The center also distributed free food to the elderly and the infirm.

The center has been run by donations and nominal fees used to pay the rent for the apartment. Shehata has continued to run the programs as aggressively as he can, but he said that even before the shooting that the center was barely scraping by.

“We have no money to build or improve anything,” he said. “We have a safe, but no money to put in it.”

 

Tense Atmosphere

In the weeks before the shooting, Teleda and the surrounding villages were gripped with fear.

Christians in the community had been receiving death threats by phone after a Muslim man died during an attack on a Christian couple. On Feb. 2, a group of men in nearby Samalout tried to abduct a Coptic woman from a three-wheeled motorcycle her husband was driving. The husband, Zarif Elia, punched one of the attackers in the nose. The Muslim, Basem Abul-Eid, dropped dead on the spot.

Elia was arrested and charged with murder. An autopsy later revealed that the man died of a heart attack, but local Muslims were incensed.

Already in the spotlight for his ministry activities, Shehata heightened his profile when he warned government officials that Christians were going to be attacked, as they had been in Farshout and Nag Hammadi the previous month. He also gave an interview to a human rights activist that was posted on numerous Coptic websites. Because of this, government troops were deployed to the town, and extremists were unable to take revenge on local Christians – but only after almost the
entire Christian community was placed under house arrest.

“They chose me,” Shehata said, “Because they thought I was the one serving everybody, and I was the one who wrote the government telling them that Muslims were going to set fire to the Christian houses because of the death.”

Because of his busy schedule, Shehata and Samir, 27, were only able to spend Fridays and part of every Saturday together in a village in Samalut, where Shehata lives. Every Saturday after seeing Samir, Shehata would drive her back through Teleda to the village where she lives, close to her family. Samalut is a town approximately 105 kilometers (65 miles) south of Cairo.

On the afternoon of Feb. 27, Shehata and his wife were on a motorcycle on a desolate stretch of hard-packed dirt road. Other than a few scattered farming structures, there was nothing near the road but the Nile River on one side, and open fields dotted with palm trees on the other.

Shehata approached a torn-up section of the road and slowed down. A man walked up to the vehicle carrying a big wooden stick and forced him to stop. Shehata asked the man what was wrong, but he only pushed Shehata off the motorcycle and told him, “I’m going to stop you from running around,” Samir recounted.

Shehata asked the man to let Samir go. “Whatever you are going to do, do it to me,” he told the man.

The man didn’t listen and began hitting Shehata on the leg with the stick. As Shehata stumbled, Samir screamed for the man to leave them alone. The man lifted the stick again, clubbed Shehata once more on the leg and knocked him to the ground. As Shehata struggled to get up, the man took out a pistol, leveled it at Shehata’s back and squeezed the trigger.

Samir started praying and screaming Jesus’ name. The man turned toward her, raised the pistol once more, squeezed off another round, and shot Samir in the arm. Samir looked around and saw a few men running toward her, but her heart sank when she realized they had come not to help them but to join the assault.

Samir jumped on top of Shehata, rolled on to her back and started begging her attackers for their lives, but the men, now four in all, kept firing. Bullets were flying everywhere.

“I was scared. I thought I was going to die and that the angels were going to come and get our spirits,” Samir said. “I started praying, ‘Please God, forgive me, I’m a sinner and I am going to die.’”

Samir decided to play dead. She leaned back toward her husband, closed her eyes, went limp and tried to stop breathing. She said she felt that Shehata was dying underneath her.

“I could hear him saying some of the Scriptures, the one about the righteous thief [saying] ‘Remember me when you enter Paradise,’” she said. “Then a bullet went through his neck, and he stopped saying anything.”

Samir has no way of knowing how much time passed, but eventually the firing stopped. After she heard one of the shooters say, “Let’s go, they’re dead,” moments later she opened her eyes and the men were gone. When she lifted her head, she heard her husband moan.

 

Unlikely Survival

When Shehata arrived at the hospital, his doctors didn’t think he would survive. He had lost a tremendous amount of blood, a bullet had split his kidney in two, and the other bullet was lodged in his neck, leaving him partially paralyzed.

His heartbeat was so faint it couldn’t be detected. He was also riddled with a seemingly limitless supply of bullet fragments throughout his body.

Samir, though seriously injured, had fared much better than Shehata. The bullet went into her arm but otherwise left her uninjured. When she was shot, Samir was wearing a maternity coat. She wasn’t pregnant, but the couple had bought the coat in hopes she soon would be. Samir said she thinks the gunman who shot her thought he had hit her body, instead of just her arm.

The church leadership in Samalut was quickly informed about the shooting and summoned the best doctors they could, who quickly traveled to help Shehata and Samir. By chance, the hospital had a large supply of blood matching Shehata’s blood type because of an elective surgical procedure that was cancelled. The bullets were removed, and his kidney was repaired. The doctors however, were forced to leave many of the bullet fragments in Shehata’s body.

As difficult as it was to piece Shehata’s broken body back together, it paled in comparison with the recovery he had to suffer through. He endured multiple surgeries and was near death several times during his 70 days of hospitalization.

Early on, Shehata was struck with a massive infection. Also, because part of his internal tissue was cut off from its blood supply, it literally started to rot inside him. He began to swell and was in agony.

“I was screaming, and they brought the doctors,” Shehata said. The doctors decided to operate immediately.

When a surgeon removed one of the clamps holding Shehata’s abdomen together, the intense pressure popped off most of the other clamps. Surgeons removed some stomach tissue, part of his colon and more than a liter of infectious liquid.

Shehata could not eat normally and lost 35 kilograms (approximately 77 lbs.). He also couldn’t evacuate his bowels for at least 11 days, his wife said.

Despite the doctors’ best efforts, infections continued to rage through Shehata’s body, accompanied by alarming spikes in body temperature.

Eventually, doctors sent him to a hospital in Cairo, where he spent a week under treatment. A doctor there prescribed a different regimen of antibiotics that successfully fought the infection and returned Shehata’s body temperature to normal.

Shehata is recovering at home now, but he still has a host of medical problems. He has to take a massive amount of painkillers and is essentially bedridden. He cannot walk without assistance, is unable to move the fingers on his left hand and cannot eat solid food. In approximately two months he will undergo yet another surgery that, if all goes well, will allow him to use the bathroom normally.

“Even now I can’t walk properly, and I can’t lift my leg more than 10 or 20 centimeters. I need someone to help me just to pull up my underwear,” Shehata said. “I can move my arm, but I can’t move my fingers.”

Samir does not complain about her condition or that of Shehata. Instead, she sees the fact that she and her husband are even alive as a testament to God’s faithfulness. She said she thinks God allowed them to be struck with the bullets that injured them but pushed away the bullets that would have killed them.

“There were lots of bullets being shot, but they didn’t hit us, only three or four,” she said. “Where are the others?”

Even in the brutal process of recovery, Samir found cause for thanks. In the beginning, Shehata couldn’t move his left arm, but now he can. “Thank God and thank Jesus, it was His blessing to us,” Samir said. “We were kind of dead, now we are alive."

Still, Samir admits that sometimes her faith waivers. She is facing the possibility that Shehata might not work for some time, if ever. The couple owes the 85,000 Egyptian pounds (US$14,855) in medical bills, and continuing their ministry at the center and in the surrounding villages will be difficult at best.

“I am scared now, more so than during the shooting,” she said. “Ephraim said do not be afraid, it is supposed to make us stronger.”

So Samir prays for strength for her husband to heal and for patience. In the meantime, she said she looks forward to the day when the struggles from the shooting are over and she can look back and see how God used it to shape them.

“There is a great work the Lord is doing in our lives, we may not know what the reason is now, but maybe some day we will,” Samir said.

 

Government Opposition

For the past 10 years, Shehata has tried to erect a church building, or at a minimum a house, that he could use as a dedicated community center. But local Muslims and Egypt’s State Security Investigations (SSI) agency have blocked him every step of the way. He had, until the shooting happened, all but given up on constructing the church building.

On numerous occasions, Shehata has been stopped from holding group prayer meetings after people complained to the SSI. In one incident, a man paid by a land owner to watch a piece of property near the community center complained to the SSI that Shehata was holding prayer meetings at the facility. The SSI made Shehata sign papers stating he wouldn’t hold prayer meetings at the center.

At one time, Shehata had hoped to build a house to use as a community center on property that had been given to him for that purpose. Residents spread a rumor that he was actually erecting a church building, and police massed at the property to prevent him from doing any construction.

There is no church in the town where Shehata lives or in the surrounding villages. Shehata admits he would like to put up a church building on the donated property but says it is impossible, so he doesn’t even try.

In Egypt constructing or even repairing a church building can only be done after a complex government approval process. In effect, it makes it impossible to build a place for Christian worship. By comparison, the construction of mosques is encouraged through a system of subsidies.

“It is not allowed to build a church in Egypt,” Shehata said. “We can’t build a house. We can’t build a community center. And we can’t build a church.”

Because of this, Shehata and his wife organize transportation from surrounding villages to St. Mark’s Cathedral in Samalut for Friday services and sacraments. Because of the lack of transportation options, the congregants are forced to ride in a dozen open-top cattle cars.

“We take them not in proper cars or micro-buses, but trucks – the same trucks we use to move animals,” he said.

The trip is dangerous. A year ago a man fell out of one of the trucks onto the road and died. Shehata said bluntly that Christians are dying in Egypt because the government won’t allow them to construct church buildings.

“I feel upset about the man who died on the way going to church,” he said.

 

Church-for-Charges Swap

The shooters who attacked Shehata and Samir are in jail awaiting trial. The couple has identified each of the men, but even if they hadn’t, finding them for arrest was not a difficult task. The village the attackers came from erupted in celebration when they heard the pastor and his wife were dead.

Shehata now sees the shooting as a horrible incident that can be turned to the good of the believers he serves. He said he finds it particularly frustrating that numerous mosques have sprouted up in his community and surrounding areas during the 10 years he has been prevented from putting up a church building, or even a house. There are two mosques alone on the street of the man who died while being trucked to church services, he said.

Shehata has decided to forgo justice in pursuit of an opportunity to finally construct a church building. He has approached the SSI through church leaders, saying that if he is allowed to construct a church building, then he will take no part in the criminal prosecution of the shooters.

“I have told the security forces through the priests that I will drop the case if they can let us build the church on the piece of land,” he said.

The proposal isn’t without possibilities. His trial has the potential of being internationally embarrassing. It raises questions about fairness in Egyptian society during an upcoming presidential election that will be watched by the world.

Regardless of what happens, Shehata said all he wants is peace and for the rights of Christians to be respected. He said that in Egypt, Christians have less value than the “birds of the air” mentioned in the Bible. According to Luke 12:6, five sparrows sold for two pennies in ancient times.

“We are not to be killed like birds, slaughtered,” he said. “We are human.”

WAR IS OVER IN SRI LANKA, CHRISTIANS ARE REACHING OUT


Sri Lanka’s civil war between the government and the Tamil Tigers rebel group is now over, and it is time to minister to the survivors, says Gospel for Asia President K.P. Yohannan, reports MNN.

“While the 30-year-long conflict has come to an end by the news of the Tamil Tigers’ surrender, in reality this is the beginning of pain and crisis for hundreds of thousands of people who are displaced,” Dr. Yohannan said. “There are 25,000 now in refugee camps, and the suffering is especially acute among the children and elderly.

“This is one of the greatest challenges and opportunities we have to minister to people in the name of Christ. We have more than 100 churches in Sri Lanka, and our people are engaged in doing whatever they can to help the suffering refugees. This is a drawn-out challenge that will be there for a long time to come.”

The bloody civil war entered its final stages earlier this year and ended with the government’s announcement Monday that it had killed Tamil leader Velupillai Prabhakaran and his son. A short time later, the handful of remaining Tamils surrendered.

The Tamils are a minority group on the island, and the Tigers were an armed militant group fighting for a separate homeland in northern Sri Lanka. The Indian state of Tamil Nadu is just across a narrow channel from the battle area.

Sri Lanka’s army chief, appearing on television news broadcasts, said that government troops claimed victory over the last Tamil stronghold, a tiny sliver of land on the northwest coast of the island.

With the end of the war, Sri Lanka is now faced with resettling thousands of refugees who fled their homes in the wake of the fighting. Many of the refugees are living in government camps that lack basic hygiene facilities. They do not have access to adequate food, water or shelter.

But physical discomfort is not the only thing they have suffered. Many lost loved ones or were permanently disfigured in the violent confrontations. The rebels were accused of using civilians as human shields, and the government is accused of inadvertently bombing a hospital in the designated safe zone.

The United Nations estimates that 70,000 civilians were killed in the fighting during the last 30 years. There is a concern that the number will increase.

“Our country is in huge suffering,” said Lal Vanderwall, GFA’s Sri Lanka country leader. “We are praying for God to intervene so that many more will not die in the aftermath of this surrender.”

Yohannan said there is a concern about the fate of the island’s Tamils in the wake of the surrender.

The hurt runs deep, says Yohannan, and “unless we preach the Gospel and somehow bring Christ into the picture, and the church moves very aggressively, cares for the suffering and the poor, and does the work of God, we may have more problems.”

“People are committing suicide out of despair,” Yohannan reported. “When they lose hope, many will just kill themselves. So there is a very real fear of increased suicides.”

Gospel for Asia-supported missionaries have been working in Sri Lanka for many years. Some are former rebel fighters, while others come from the majority Sinhalese population. Most of these missionaries now serve as pastors of Sri Lankan churches. The fact that Tamil and Sinhalese Christians work side-by-side has been a tremendous witness to the people.

Today these pastors, along with the workers at the Bridge of Hope children’s centers, are mobilizing to help war survivors. During the next few days they will be gathering food, clothing and other daily necessities to help the displaced with their immediate needs.

As the people return home, these pastors and other workers will continue helping them rebuild their lives in whatever ways are necessary. For some, that could mean ministering to families who are burying their dead. For others, it could be providing food and other household necessities. Others may need new homes if theirs were destroyed in the conflict.

Yohannan says many are hopeless. “When people are hurting and in despair, hopelessness sinks in, and that’s when the Gospel is presented and they cry out to God.”

With the end of the war, GFA-supported missionaries will also be praying for their country’s leaders as they plot a course for the future.

“I pray that somehow the international community will be concerned that the government of Sri Lanka will take care of its Tamil population,” Yohannan said. “This conflict started because of the abuse of the Tamil population, so I pray that the government will now take care of its Tamil people as well as the majority Sinhalese.”
