Since most of the infections are passed on by the transmission of bacteria, virus, fungus or parasites from one host to another or from an infected substance or person, precautions must be taken that you don’t expose yourself to an infectious attack. Refrain from making contact with the infected person. For example, strict social distancing is recommended in the times of Covid-19 and people are advised to use masks. Similarly, make sure you don’t consume infected food or contaminated water. Avoid having sexual relationships with persons whose medical history you don’t know. Prevention is the best medicine if you want to protect yourself against infections.
