So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
Why are diseases caused by viruses often difficult to treat?
Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge. Viruses pose a challenge to the body’s immune system because they hide inside cells.
What disease is contracted by the highest number of healthcare workers each year?
4). In hospital workers the annual mean rate of recognised OIDs was highest for TB (5.7/100,000) followed by HCV (4.8/100,000).
Why are paper towels most appropriate for drying hands in a health care facility?
They found that paper towels, “reduced the numbers of all types of bacteria on the hands” and hot air dryers were the least effective method of removing bacteria from washed hands. Many studies have found that friction is the key component in hand drying as it helps to remove contamination.
Can almost all bacteria be destroyed by antibiotics?
Antibiotic resistant bacteria are bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic. Most infection-causing bacteria can become resistant to at least some antibiotics.
