Health experts have taken the time to explain the 21 Days Lockdown which will see businesses close and people holed up inside their properties as the government tries to curb the spread of COVID-19.
According to The Chronicle, Mpilo Central Hospital clinical director, Dr Solwayo Ngwenya explained the logic behind the lockdown and said:
So, if someone gets a virus today, it won’t show until at least ten to fourteen days later. Now the 21-day period is to say people who got infected yesterday for example, are going to show signs during this period. This is because everyone is locked down and unable to move around.
Around day 13 or 14 of the lockdown, these people will now be ill and they will then seek medical attention and will be removed from the community and taken to centres of isolation where they will be treated. Therefore, by removing them they haven’t moved around the community as they were contained in their house.
Now that they are taken away the other members of the family will also start showing signs and hopefully all of them will show symptoms within the 21-day period. Then when these people have been taken away if the rest of the community is allowed to move around, the scientific thinking is that the infection has been curtailed.
What happens is that this 21-day lockdown slows down the infection rate because you have removed people and taken them to isolation centres and they haven’t been able to infect as many people as if they were freely roaming around.
You may be forced to do another cycle of 21-days or more to contain the virus according to how it is remaining in the community. So over time, the virus keeps being suppressed because less and less people are passing it onto the next person thus that’s what the scientific way of a lockdown is.
Another expert, National University of Science and Technology’s Applied Genetics Testing Centre (AGTC) director Mr Zephaniah Dlamini also said:
Symptoms show after 14 days thus let’s assume that someone has been infected in the last seven days or today, so within 14 days he/she will be showing symptoms. So it’s best to then isolate everyone then if there are those who are infected they will show symptoms and will be quarantined and treated. If they are left to interact with other people they will be infecting them without knowing
