How do disease-causing germs invade my body?

The disease-causing germs invade the human body through mouth, nose, eyes, urinary or genital openings, and wounds or bites that reach the lower skin dermis. The germs can spread through contact with infected body fluids, skin or mucus to cause communicable diseases. These germs can also spread by indirect contact with doorknobs, faucet handles, etc.

Infected droplets released into the air while speaking, sneezing or coughing can also spread infection. Also, contaminated blood, food or water can help pathogens like Escherichia coli and Salmonella sp. enter the human digestive system. A study has shown that “fleas, mites, ticks, rats, snails, and dogs” are the most studied vectors of infection. A website has shown that the germs on hands can transfer to raw food items or vice versa.
