Insorts : The crisis of Corona epidemic is deepened in the country. Meanwhile, one term we are hearing often and this term is the positive rate of corona virus. It is also mentioned in the figures presented by the government. So, let us know what happens, why is it so important for the corona virus’s positivity rate and prevention of infection?

What is Positivity Rate

In general, the positivity rate is the data that shows how many positives are coming out of the total test being done. A low positive rate is considered a good sign. At the same time, the high rate of positivity indicates that the infection is spreading rapidly.

How is it calculated?

Calculating the positivity rate is quite a difficult task. The reason for this is that many times people get their corona test done many times, which makes it difficult for the government to calculate the positivity rate. It has many formulas, but the most common formula is that the number of people found corona positive is divided by the total number of people who get corona test multiplied by 100. The number you will get after doing this will be the positivity rate of an area.

All positive cases / total test done x100 = positivity rate

It is to be noted here that if the positivity rate in an area is 24 per cent, then it does not mean that 24 per cent of the people in this area are corona positive. Rather, it means that out of the total tests conducted, 24 percent are found to be corona positive.
