Professor Neelika Malewige, of the Immunology and Molecular Medicine Studies Division, of the Sri Jayewardenepura University, told Ceylon Today the possibility of a person who had been infected with the Covid-19 virus getting infected again was negligible. .

Professor Malewige pointed out that a person who has contracted the Covid-19 virus and recovered will not get infected again within a period of three months and there have been no reports so far that anyone had contracted the virus again after three months. She also said that although there was no possibility of re-infection after a period of three-months, research is being carried out further to confirm it. 

Since the Covid-19 virus is just one virus and because all types are 99 percent equal, the possibility of a person who was infected with the virus and has recovered contracting it again is very little, Professor Malewige said. 

Although during the initial period it was reported that one or two persons who had recovered from the Covid-19 virus had contracted it again, what had happened on those occasions is that the person had not been infected again but the test for Covid-19 had come out positive, only. This test for the virus will come up positive in people who have recovered from the virus, for a short period after that, nevertheless after 10 days a person who had been infected with the virus cannot transmit it to anyone else. This has been proven through tests Professor Malewige said.  Professor Malewige said that a person who has had Dengue can be infected again by the Dengue virus since there are four types of the virus prevalent. There are only 75 percent similarities among these four types, which is the reason for re-infection she pointed out further. 

The unequal conditions in the Dengue virus is between the range of 25% to 30%. As a result there is a possibility of a person who has had Dengue once, contracting the virus again, Professor Malewige said.
