Viruses often remain in the body for years, hide or ally themselves with the cells of the immune system, and they can manifest again even after some time. Viruses include all those microorganisms such as the Herpes Zoster virus, the Ebola virus or HIV. Today, bacteria are treated with antibiotics, whereas viruses cannot be killed by antibiotics. Also known as the miracle medicine, penicillin has been in hospital care protocols since 1944. Both have been, and still are, a threat to mankind.Īmong the bacteria that we know are, for example, staphylococci and streptococci, for which a cure was found in 1928 with Alexander Fleming’s penicillin. Viruses are extremely small and can only be seen under a microscope. There is a difference between viruses and bacteria. They are microorganisms that live according to their own ecosystem. Viruses, like bacteria or fungi, are part of our world.
