Ballari rise in COVID cases sign of Community transmission?
The sudden surge in Covid-19 cases in the city has put the public in shock. The district administration claims that this is because of increased testing using the rapid antigen detection kits. Mr. S.S Nakul the Deputy Commissioner of Ballari said that this is an aggressive approach to identify COVID cases at an early stage and treat them.
If the number of positives is increasing drastically along with the number of tests, then it does reflect that there is community transmission. Community transmission is when there is no clear source of origin of the infection in a new community. It happens when you can no longer identify who became infected after being exposed to someone who interacted with people from the originally infected communities.
The positivity rate needs to be below 5 per cent consistently for at least two weeks and only then, the curve will flatten.
There are three basic reasons why the positivity rate is going up. One, the number of tests along with rapid antigen testing is going up. Two, the intensity of contact tracing aggressive and high-risk contacts being tested is also going up; and third, the total number of tests is increasing and the denominator is also increasing, which is why the positivity rate is also increasing.
