Explanation:
When a mosquito bites a person who has dengue fever, the mosquito becomes infected with the virus that causes the disease. It can then spread the virus to other people by biting them. Dengue fever is not contagious, so it can't spread directly from person to person.

Answer:
A
When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. Then, when the infected mosquito bites another person, the virus enters that person's bloodstream and causes an infection.
