It's not known. A few reports from China say some people had COVID-19, recovered and then fell ill again. It's unclear if that's a relapse, a new infection, or a case where the person never fully recovered in the first place. Scientists at the Fred Hutchinson Cancer Research Center in Seattle say the 30,000-letter genetic code of the virus changes by one letter every 15 days. It's not known how many of these changes would be needed for the virus to seem different enough to the immune system of someone who had a previous version of it for it to cause a fresh infection.

Experts say the effects appear to depend on how robust or weakened a person's immune system is. The WHO and the Centre for Disease Control (CDC) have said that the two major groups of people who are more likely to be affected by the disease are the elderly and those with underlying medical conditions. People who have aged and have weak immune systems have a harder time fighting off the COVID-19 infection. People who already have an underlying health condition like heart disease, diabetes or lung disease are more prone to the infection causing severe symptoms. People with these underlying problems have a taxed immune system and cannot fight off the infection. However, you need to take the necessary precautions even if you are young and healthy.

According to WHO, only wear a mask if you have been diagnosed with COVID-19 or looking after a patient of COVID-19. A disposable face mask can only be used once. If you are not ill or looking after someone who is ill then you are wasting a mask. Wear a mask if you are coughing or sneezing. Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water. If you wear a mask, then you must know how to use it and dispose of it properly.
