<h3>What causes infectious diseases?</h3>

Coming into contact with a person or an animal who has the virus is one of the most straightforward ways to obtain the most contagious or infectious diseases. Direct contact, such as person-to-person contact, can transfer contagious diseases. Direct transmission of bacteria, viruses, or other germs from one person to another is the primary method by which contagious diseases are typically disseminated. If someone who is unaffected touches, kisses, coughs, sneezes, or has the virus or bacterium on them, this could happen. Additionally, these pathogens can disperse through sexual contact and the exchange of bodily fluids. The person who spreads the infection may only be a carrier and not exhibit any signs of the illness.
