Which is the difference between an antibiotic and an antiviral?

There are no options in this question, the options are as follows:

A. Antibiotics build up immunity, and antivirals increase white blood cells.

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
