    Direct contect

    Three ways infectious diseases can be spread through direct contact are:

    Person to person :
    A common way for infectious diseases to spread is through the direct transfer of bacteria, viruses or other germs from one person to another.

    This can occur when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.

    These germs can also spread through the exchange of body fluids from sexual contact. The person who passes the germ may have no symptoms of the l disease, but may simply be a carrier.

    Animal to person : Being bitten or scratched by an infected animal – even a pet – can make you sick and, in extreme circumstances, can be fatal. Handling animal waste can be hazardous, too.
    For example, you can acquire a toxoplasmosis infection by scooping your cat’s litter box.

    Mother to unborn child : A pregnant woman may pass germs that cause infectious diseases to her unborn baby. Some germs can pass through the placenta. Germs in the vagina can be transmitted to the baby during birth.

    Indirect contact : Insect bites – Some germs rely on insect carriers — such as mosquitoes, fleas, lice or ticks — to move from host to host.

    These carriers are known as vectors. Mosquitoes can carry the malaria parasite or West Nile virus, and deer ticks may carry the bacterium that causes lyme disease.

    Food contamination : Another way disease-causing germs can infect you is through contaminated food and water.

    This mechanism of transmission allows germs to be spread to many people through a single source. E. coli, for example, is a bacterium present in or on certain foods — such as undercooked hamburger or unpasteurized fruit juice.
