Acute infections, which are short-lived. Chronic infections, which can last for weeks, months, or a lifetime. Latent infections, which may not cause symptoms at first but can reactivate over a period of months and years.
Most minor cases of viremia eventually resolve on their own without direct medical treatment. Viremia can allow viruses to spread through the blood and infect tissues and organs throughout the body. Since many viruses kill host cells, long-term or severe viremia can cause damage to infected tissues and organs.
Treatment of a Viral Infection Take it easy. Get lots of rest. Drink plenty of fluids. Gargle with salt water. Sip a hot beverage. Have a spoonful of honey. Take an antiviral medication, if one is prescribed.
Some viruses, such as hepatitis B virus and hepatitis C virus, can cause chronic infections. Chronic hepatitis can last for years, even decades.

Viremia is a medical term for viruses present in the bloodstream. A virus is a tiny, microscopic organism made of genetic material inside a protein coating. Viruses depend on a living host, like a human or animal, for survival. They survive by invading cells and using those cells to multiply and produce other viruses.
In addition to aches and pains, chills are another tell -tale sign that your body may be fighting off a virus. In fact, chills are often one of the first symptoms that people notice when they’re coming down with the flu.
Even if symptoms are not severe, you should see a doctor if they persist for more than three weeks or recur. These include having a persistent cough (with or without discharge), chest pain or soreness, sore throat, body aches, or persistent fatigue.
Bacterial Infections Symptoms persist longer than the expected 10-14 days a virus tends to last. Fever is higher than one might typically expect from a virus. Fever gets worse a few days into the illness rather than improving.
Definition. Persistent infections are characterized as those in which the virus is not cleared but remains in specific cells of infected individuals. Persistent infections may involve stages of both silent and productive infection without rapidly killing or even producing excessive damage of the host cells.
If someone with a viral infection sneezes or coughs near you, you can breathe in droplets containing the virus. Examples of viral infections from inhalation include the flu or common cold. Ingestion. Food and drinks can be contaminated with viruses.
Symptoms usually appear from one to four days after exposure to the virus, and they last five to seven days. For people who’ve had a flu shot, the symptoms may last a shorter amount of time, or be less severe. For other people, the symptoms may last longer.
