It is a well-known fact that coronavirus or Covid-19 infection causes fever, cough, loss of taste and odor in the human body.
But there are some people who do not have any symptoms.
They don't even know they're carrying the coronavirus - and most frighteningly, they're silently infecting others.
Scientists say it is important to know exactly how many people have had such "asymptomatic" infections, and whether these "silent spreaders" are responsible for the widespread spread of the virus.
What happened to that church in Singapore?
Those who gathered for Sunday morning prayers at The Life Church and Mission in Singapore on January 19 did not expect the global outbreak of the coronavirus to begin.
An elderly couple attended the prayer that day.
At that time, many people in China knew about coronavirus infection, but everyone thought that if someone was infected with Kovid-19, it would be understood by looking at his frequent cough.
The couple were both 58 years old - neither had a cough, nor did they have any other symptoms or health problems. As a result, no one in the church had any reason to think otherwise.
The problem is, they arrived in Singapore that morning from the Chinese city of Wuhan - then the epicenter of the coronavirus infection.
As soon as the prayer was over, they left the church.
After three days, things started to take a turn for the worse. The woman first fell ill on January 22, and her husband fell ill two days later.
Within a week, three locals in Singapore fell ill. Where and how they became infected - no one could understand.
Detective Detective: “We went absolutely stupid. How can people who have no symptoms get infected? ” - Says Vernon Lee, Head of Infectious Diseases, Ministry of Health, Singapore.
With all the knowledge they had about Kovid-19 at the time, they could not understand how the disease was spreading among the people.
Dr. Lee then began an investigation with police and infectious disease experts. He made a map of who was when and where. Contact tracing is the way to find out how the infection has spread and how to prevent the spread of the disease.
It is said that the investigators in Singapore are very skilled in this work. Within a few days he spoke to 191 people in his church, and found out that 142 of them were in prayer that Sunday. It also turned out that two of them were infected - they were in the same prayer with the Chinese couple. Lee.a gives an idea of how the infection spread. But the unanswered question is: “The Chinese couple had no signs of infection. So how did they spread the virus? ”There was no answer to a more difficult puzzle. That is, the 52-year-old Singaporean woman who was the third infected person - she was not present at the prayer. But he was present at another ceremony in the same church that day. How did he get infected then?Unexpected evidence was found on CCTV
Investigators began examining the church's CCTV footage to find the answer. An unexpected piece of information emerged. A few hours after the Chinese couple left the church, the victim came and sat in the same chair.
Understandably, the Chinese couple may not have had any illness or symptoms of their own - but they may have unknowingly transmitted the coronavirus to others. Maybe they had the virus in their hands, or maybe they spread it from their breath. It's not clear what happened - but the significance was huge.
