Answer:
A)HPV
Step-by-step explanation:
There are HPV vaccines. However, these vaccines are prophylactic (ie preventive) rather than therapeutic. Its optimal efficacy occurs if administered, therefore, before exposure of individuals to HPV.
HPV (short for human papilloma virus) is a highly contagious virus, with sexual contact being the main (but not the only) means of transmission of this infection. To get an idea, it is estimated that about 50 to 70% of people with sexual activity will, at some point in their lives, become infected with HPV. In a small percentage of those who get the infection, HPV can cause lesions on the skin and mucous membranes, called anogenital warts (similar in appearance to cauliflower). HPV is also capable of causing persistent infection in cases where the body cannot spontaneously eliminate it.
