What a is Viral Infection
A viral infection is a type of illness that occurs when a virus invades and multiplies in the body. Viruses are microorganisms that can cause a wide range of diseases in humans, animals, and plants. They are much smaller than bacteria and can only replicate within an organism’s living cells.
When a virus enters the body, it can attack and invade healthy cells, causing illness symptoms. Fever, fatigue, muscle aches, cough, and sore throat are all common symptoms of a viral infection. Some viral infections, such as the common cold, are mild and resolve on their own, whereas others, such as HIV and influenza, can be severe and require medical treatment.
How does a viral infection
It must multiply within a living cell. A viral infection can cause symptoms ranging from asymptomatic (no overt symptoms) to severe disease. People can contract viruses by swallowing or inhaling them, being bitten by insects, or having sexual contact with them.
How do I know if I have a viral infection?

Digestive symptoms: nausea, vomiting, diarrhoea.
Skin conditions: rashes, sores, blisters, warts.
Is a viral infection serious?
Viruses are responsible for common infectious diseases such as the common cold, flu, and warts. They also cause serious illnesses like HIV/AIDS and Ebola. Viruses are similar to hijackers. They infiltrate normal, living cells and use them to multiply and produce more viruses like themselves.
What are symptoms of a viral infection?
If it’s a viral illness, the symptoms are typically shorter-lasting and include fever, chills, sore throat, nasal congestion, runny nose, cough, and, in some cases, body aches.

How does a viral infection end?
By three to four days after infection, there are enough virus-specific lymphocytes to mount an effective immune response against the virus. To keep the infection under control, the immune system must both destroy virus-infected cells and prevent virus spread between cells. Coughing and Sneezing—During a viral infection, the fluid from a runny nose may change colour from clear to yellow to green within a few days. 4 Mucus is designed to trap invading viruses, which are then expelled from the body via coughing and sneezing. Colds, flu, chickenpox, measles, and warts are all caused by viruses. The majority of the time, viral infections can be treated. You can treat the symptoms and wait for them to go away.
