Viral Infection Types Symptoms And Management

Viruses are tiny germs that easily spread from one person to another. Whenever you contract a Viral infection such as flu or cold, your Immune system responds and goes into overdrive, causing the body temperature to rise so that a less hospitable environment for the germs and viruses is created.

Viruses are infectious agents made up of DNA or RNA, including the coat of protein that antibiotics cannot destroy.

Viruses invade the body cells and use the components of the body cell to multiply. In this process, the infected cells are destroyed or damaged.

The common symptoms include nausea, vomiting, diarrhea, and abdominal cramps. A few examples of gastrointestinal viral diseases include rotavirus infection, norovirus infection, astrovirus infection, and in some cases, adenovirus infections.

Gastrointestinal viral diseases spread through food or water contaminated by feces or sharing personal objects or utensils contaminated by the infected person.

In most cases, GIT viral infections resolves on their own in a day or two. However, to replace the lost fluids, drink lots of fluids.

Hepatitis C is transmitted through bodily fluids, such as blood contact on sharing razors or needles or during a blood transfusion.

Hepatitis B transmits through sexual contact. Hepatitis A and E contracts by consuming infected water of food. Those who have hepatitis B virus can develop Hepatitis D. 

The treatment of hepatitis A and E includes supportive measures such as drinking lots of fluids, avoiding alcohol, and rest. In hepatitis B, C, and D, along with managing symptoms, the doctor may also prescribe antiviral drugs.
