Infections

Infections are caused due to the invasion of the foreign cells; say for instance bacteria in the human body can harm the host organism. In general, the host organism is said to be colonized. Lots of agents will cause infection like parasites; fungi and viruses, there are times when these will work to prevent the infection too. For instance sometimes you are given antibiotics so that you are prevented from the disease. Infections are nothing but harm to the host, the harm may be currently induced, and they require medical attention. The infections get transmitted through contact, airborne, vector, droplet and vector.
