Document Summary
Hiv is more prevalent in developing nations, especially those that reside in sub- Reasons why hiv is more common in some parts of the world than others. Reasons for why there is no cure or universal vaccine for hiv/aids. Because hiv is a retrovirus it mutates rapidly due to mistakes made by the enzyme reverse transcriptase when changing rna into dna. These mutations combined with the rapid reproduction of the virus make it difficult for researchers to find a cure or universal vaccine because the virus will mutate and the treatment will no longer work on the mutated virions. Reasons why anti-viral therapies often have serious side effects. Anti-viral drugs and therapies usually have serious side affects because the drug is not able to attack the pathogens directly and instead must inhibit its development by damaging the particular host cells that the virus infects.
