KUALA LUMPUR (Bernama): People whose test results for Covid-19 come back negative remain at risk of being infected with the virus, says the Health Ministry’s (MOH) family medicine specialist Dr Zienna Zufida Zainol Rashid.

She said that might happen if such individuals are exposed to risk, such as having close contact with a Covid-19 patient.

"In this situation, the person may get infected. ... if you tested negative once, (this) does not mean you will remain negative in the future, ” she said during the Ministry’s Facebook live-stream on ‘Kenali Covid-19’ (Get to know COVID-19) Friday (April 3).

The live-stream, which also included the Ministry’s medical specialist Dr Aizuniza Abdullah, was aimed at answering questions on Covid-19 posted by the public.

Elaborating, Dr Zienna said it was therefore important for people to adopt preventive measures such as washing their hands, social distancing, and staying at home to contain the spread of the outbreak.

Meanwhile, on claims that vitamin C could prevent Covid-19, Dr Zienna said so far no studies have proven it.

"Generally, vitamin C can be taken as a supplement but not to prevent Covid-19. No studies have suggested it, ” she said. – Bernama
