Can Certain Individuals be Naturally Immune to COVID-19?

To avoid COVID-19 infection, people should avoid high-risk environments and practice precautions like mask-wearing and handwashing; some people may have been able to avoid exposure more than others.

Avoiding High-Risk Environments

Asymptomatic cases of COVID-19

Nearly 40.5% of COVID-19 cases are asymptomatic, meaning some who never tested positive might have had COVID-19 but didn't show any symptoms.

Undetected asymptomatic cases of COVID-19 may provide some level of immunity against reinfection, according to experts, but vaccination is still the strongest protection against the virus.

They Are Vaccinated

Vaccination and boosters are crucial in lowering the risk of COVID-19 infection and preventing severe illness and death, although breakthrough cases may still occur due to new variants, as stated by the CDC.

COVID-19 tests, including rapid at-home tests, may produce false negatives due to factors such as low viral load, mild cases, improper sampling, and being less sensitive to newer variants.
