Asymptomatic carriers: What you need to know

Infected persons who do not show symptoms or tell-tale signs of Covid are asymptomatic carriers. Why are some carriers asymptomatic? Some experts say it is either due to the body's stronger innate immune response to the virus or because some people are exposed to a smaller viral load.

Can asymptomatic carriers transmit the virus? The World Health Organisation confirms that infected people can transmit the virus irrespective of whether they have symptoms or not.

Preliminary studies in South Africa show that Omicron has a much higher rate of “asymptomatic carriage” than earlier variants. Also, the number of asymptomatic carriers are proportionately higher. Omicron symptoms have been less severe than that of other variants.

Doctors say it's not advisable to exercise while battling Covid, even if you are asymptomatic. That's because one needs rest in case of all viral infections to help the immune system fight the infection. It’s better to go for simple stretching or mild walks in isolation than heavy exercises.

Is there a way of knowing you are an asymptomatic carrier? As of now, there is no other way other than tests. There are self tests and antigen tests and PCR tests. Of these the PCR tests are the most accurate. Doctors advise to go for a test if there is confirmed contact with an infected person. And to self isolate and observe all Covid protocols even if you are an asymptomatic person.
