  1. CDC defined ‘close contact for Covid-19

The CDC (centers for disease control and prevention) expanded the terminology widely in use these days often referred to as ‘close contact’. As per the updated guidelines, a close contact is someone who is available within 6 feet of an infected person for a cumulative period of 15 minutes or more, over a 24- hour period( that starts from 2 days before illness onset or 2 days prior to testing specimens of asymptomatic patients). This happens when the patient is not in isolation or any sort of quarantine. Although according to the previous definition, a ‘close contact’ was someone who was at least 15 consecutive minutes within 6 feet of a confirmed Covid 19 case. However, the new reports clearly say that an individual who had a series of short contacts adding up to more than 15 minutes has become infected.

9. Herd Immunity or misconception?

Herd immunity is an approach adopted by most of the countries to allow immunity gain in low risk and protect the vulnerable groups. But somehow, it was not supported by scientific evidence( as signed by 80 international researchers). According to the letter published in the journal the Lancet, the careless transmission in the young population poses significant risks, since there is no evidence for long lasting immunity to SARS- CoV. And it could be responsible for repeated waves of increased active Corona cases over years. So, herd immunity might prove a deadly fallacy later on.
