What is the best medication for a viral infection?
The drugs used for viral infection are Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are effective against herpesvirus, including herpes zoster and herpes genitalis. Drugs used for treatment for viral fever are Acetaminophen(Tylenolothers)ibuprofen (Advil,motrin IB others).

Strictly speaking, viruses can’t die, for the simple reason that they aren’t alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can’t thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
What helps your body fight a virus?

Do viruses die in air?
A cold virus can sometimes survive on indoor surfaces for several days, although its ability to cause infection drops dramatically over time. Flu viruses can survive in the air for several hours, especially at lower temperatures, and on hard surfaces they can survive and remain infectious for 24 hours.
What’s the symptoms of a viral infection?
Bacterial and viral infections can cause similar symptoms such as coughing and sneezing, fever, inflammation, vomiting, diarrhea, fatigue, and cramping — all of which are ways the immune system tries to rid the body of infectious organisms.
Does viral mean you’re contagious?
You’re contagious before you have symptoms — during the incubation period, when the virus enters your system. And just because you feel better doesn’t mean those around you are safe. In fact, you’re still contagious after symptoms subside, carrying a bacterial or viral infection that can spread to others.

Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Do viral infections go away on their own?
Most viral infections tend to resolve on their own without treatment so any treatment generally is aimed at providing relief from symptoms like pain, fever and cough. How are they spread? Both viral and bacterial infections are spread in similar ways: Coughing and sneezing.
Do viruses feed on sugar?
Bacteria and viruses have a sweet tooth! It’s no coincidence when these microorganisms attack the human organism to make us ill, for example when they give us pneumonia or flu. The great majority, around 80%, of these bacteria and viruses seek out the sugars on the surface of our cells.
