One new COVID-19 case in quarantine recorded in Thailand
Thailand recorded one new COVID-19 case among those in state quarantine today.
The new case is a 35-year old Indian national, who arrived in Thailand from India on August 8th, on the same flight as 22 others who earlier tested positive for COVID-19. He was cleared of any infection in the first test, but the second test, on August 21st confirmed the infection, while no symptoms were evident.
Cumulative infections in Thailand, to date, are 3,404, with 3,237 recoveries and 58 deaths. 109 others are still in hospital.
Meanwhile, Dr. Yong Pooworavan, a well-known virologist at Chulalongkorn University, said in his Facebook post on Wednesday that people who have recovered from COVID-19 infection can be re-infected because post infection immunity does not last long.
Citing a case of re-infection in Hong Kong, he said the patient was first infected by the V strain of the virus and, four months later, by the G strain.
He said that, in the first infection, immunity was not detected in the first ten days and, in the second, immunity was detected five days after infection.
He said that the conditions of re-infected people are not serious, adding that people with weak immune systems have a greater chance of becoming re-infected.
