Bacteria and viruses can live outside of the human body (for instance, on a countertop) sometimes for many hours or days. Parasites, however, require a living host in order to survive. Bacteria and parasites can usually be destroyed with antibiotics. On the other hand, antibiotics cannot kill viruses.
Also to know is, what needs a host to survive?
All a pathogen needs to thrive and survive is a host. Pathogens can be transmitted a few ways depending on the type. They can be spread through skin contact, bodily fluids, airborne particles, contact with feces, and touching a surface touched by an infected person.
Beside above, how long do bacteria live on surfaces?
On suitable indoor surfaces, cold germs can linger for days, but fortunately they rarely remain infectious for more than 24 hours.
Are viruses smaller than bacteria?
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Also unlike bacteria, most viruses do cause disease, and they're quite specific about the cells they attack.
Can bacteria live on clothes?
Germs on clothes and towels can come from our own body. We all have bacteria on the surface of our skin, in our noses and in our gut. Germs can also get onto outer clothing if you handle contaminated food or brush against a soiled object. Most germs can survive on fabrics for some time.
