Some people believe that once they recover from COVID-19, they’ll have immunity from the virus, so they won’t get infected again. Though it is true that those who recovered from the coronavirus develop protective antibodies, it’s not yet clear how long the protection will last.
Having said that, individuals who recovered from the coronavirus should still be careful, especially since cases of COVID-19 reinfections have been reported. The World Health Organization (WHO) has also confirmed on April 24 that a second infection is possible.
This is why the Centers for Disease Control and Prevention (CDC) is actively working to learn more about COVID-19 reinfections. They have coordinated with state and local health departments to investigate the cases of people getting infected again with the coronavirus.
In some cases, people who are reinfected with COVID-19 may experience milder symptoms compared to when they first had the virus. Experts believe that this is due to the antibodies that were developed during the first infection. However, this is not always the case.
Some reports say that those who get infected for the second time may experience worse symptoms and a more serious illness than the first. Researchers believe that this is because the patient has been exposed to a more virulent dose of the virus.
Experts are still trying to figure out whether people who got reinfected can transmit the virus to other individuals. This is why they are advised to be more careful and follow precautionary measures like everyone else.
As a result of the initial infection, individuals may still experience symptoms of COVID-19 weeks or even months after their recovery. Because of this, some people may believe that they’ve never really recovered from the virus.
To test if the person has been reinfected, medical practitioners run genetic analyses of the samples. They would compare the second specimens from the ones taken during the first infection. If the samples show genetically significant differences, then the doctors can determine that the individual has been reinfected.
