Infections (Bacterial and Viral)

There are a variety of infections that can quickly affect your body, with the main being bacterial and viral infections. Bacterial infections occur when single-celled organisms (bacteria) invade an organism, while viral infections are caused by viruses and more difficult to treat. The last type of infection is called a fungal infection which affects someone’s skin.

Bacterial Infection

The most common type of infection a person can get is a bacterial infection, however not all types of bacteria cause infections. There are a lot of different types of bacteria found in the body that are good bacteria and are needed for good body function. However, these good bacteria can become abnormal and cause certain infections, as well as bad bacteria coming in contact with the person which leads to an infection. The two common types of bacteria that cause infections are staphylococci and streptococci. Staphylococci is the bacteria that causes “staph” infections such as skin conditions like impetigo or cellulitis. Streptococci is the bacteria that causes “strep” infections like a strep throat which is the most common type of strep infection. The treatment for bacterial infections usually involves antibiotics that are given orally or topically. Some types of bacteria can’t be treated by antibiotics due the bacteria becoming resistant, in which other treatments need to be considered.

Viral Infections

A virus involves an organism with a nucleic acid molecule surrounded by a protein shield that can cause a variety of illnesses, including a viral infection. When this virus comes into contact with the body, it will take over a living cell which can produce more viruses within the body and lead to infection. Some of the common types of viral infections are influenza (flu) and chicken pox, as well as HIV and AIDS. Many viral infections can be prevented with the proper vaccinations or in the case of HIV and AIDS, avoiding contact with someone who has the virus. Treatment for viral infections include antiviral medications, though they aren’t always successful. Some viral infections are simply treated by treating the side effects or symptoms of the infection.

Fungal Infections

The last type of infection is categorized as a fungal infection, which is also quite common. This is caused by fungus which can come from any living organism, such as plants. They are found in the soil, air and water. Skin infections are often caused by fungal infections such as ringworm, yeast infections, and athlete’s foot. Treatment includes a topical antifungal medication.
