PEP or post-exposure prophylaxis is a method for preventing a disease that involves taking medication. When you take measures to protect yourself from getting a disease, it is called prophylaxis. PEP is a type of prophylaxis for people who do not have the disease but has been exposed to someone who has been confirmed to have the disease.
PEP is taken after exposure, preferably within 3 to 4 days of exposure for two weeks. Studies are being established and conducted to investigate the effectiveness of PEP for COVID-19.
