The Virus

Virus 31st May 2020
On 19^th January, a couple from Wuhan in China went to a church service in Singapore.  They were healthy – had no cough or temperature.  On January 22^nd, the wife became ill, and then the husband.  A few days later, three people from Singapore became ill.|They sent in the “disease detectives”.  They found that the 3 Singapore people were all members of the same church.  Two of them had been at the same service … so they must have had some contact.  But the third person had been at the church at a different service. 
It was a puzzle, until they found out that the third person had sat in the same seat as the couple from China.  Somehow the virus is left on objects for others to touch.
So now we have rules of social distance and washing hands a lot.
But, the big problem is that the virus was transmitted before the people had symptoms.This is why “test, track and trace” will not solve the problem as people spread the virus before they have symptoms.  We have to test people before they have symptoms.
