Contrary to reports claiming humid weather is likely to promote the spread of Covid-19, All India Institute of Medical Sciences Director Dr Randeep Guleria said that there won’t be any “dramatic change” with the coming of monsoon in the spread of the novel virus in the country.

Earlier, a study by two professors of the Indian Institute of Technology-Bombay had claimed that hot and dry weather reduces the risk of Covid-19 spread while humid weather is likely to promote it.

“I don’t think there will be any dramatic change with the coming of monsoon. When summers came, there was a lot of talk that the virus spread will be halted but that did not happen,” AIIMS Director Dr Randeep Guleria said in an exclusive interview to India Today.

Dr Guleria said that doctors will require a change in terms of diagnostics as vector-borne diseases such as dengue, chikungunya, that come with similar symptoms as Covid-19, will increase during the monsoon season.

“We will see a change in terms of the diagnostics that doctors will need because a lot of vector-borne diseases like dengue, chikungunya also present with fever etc, can mimic some of the symptoms that you see with Covid-19. Therefore it will be a challenging time in terms of differentiating Covid from other diseases that we see to a large extent during monsoon,” Dr Guleria said.

On being asked whether a cured Covid-19 patient can get infected again, Dr Guleria said it is highly unlikely that once someone has recovered from Covid then he/she will get it again or get a severe form of the virus.

“It is highly unlikely that once you have recovered from Covid you will get it again or get a severe form of Covid. That’s based on the fact that there are certain types of antibodies that are formed in your blood which give you some degree of immunity, preventing you from getting the infection again,” he said.

Dr Randeep Guleria added that even if someone has an exposure, they will have it in a very mild form. However, how long does this immunity last is not clear yet, he said.

How long does this immunity last, does it last for a few weeks, for a few months or longer, that we are not very clear about. But, this does give you some degree of protection and therefore the chances of a person who has recovered from Covid getting the infection again is very very low,” Dr Guleria said.
