Previously having COVID-19 may give you some immunity against getting COVID-19 again. But it’s possible to get COVID-19 again, especially since newer variants of COVID-19 are more contagious.
In some cases, people develop long-haul COVID-19 and have symptoms, either new or ongoing, that last for weeks, even months. This can happen even if you initially have few or minor symptoms.
According to the Centers for Disease Control and Prevention, the best way to prevent the long-term effects of COVID-19 is for you to get a vaccine, even if you’ve already had COVID-19.
