Answers
Answer:
(i) Dengue fever is caused by any one of four types of dengue viruses spread by mosquitoes that thrive in and near human lodgings.
(ii) When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. When the infected mosquito then bites another person, the virus enters that person's bloodstream. Like this the dengue fever is spread.
(iii) If I was Ganesh then I would prevent dengue fever by avoiding mosquito bites. And I would also take a dengue vaccine and keep my surrounding clean and green to avoid mosquitoes.
Explanation:
All four dengue viruses are spread primarily through the bite of an infected Aedes species (Ae. aegypti and Ae. albopictus) mosquito. These mosquitoes also spread chikungunya and Zika viruses.
The mosquitoes that spread dengue are found in most tropical and subtropical regions of the world, including many parts of the United States.
Ae. aegypti and Ae. albopictus bite during the day and night.
A dengue vaccine is available for use in some parts of the world, including the U.S. territories of American Samoa, Puerto Rico, and the U.S. Virgin Islands, and freely associated states, including the Federated States of Micronesia, the Republic of Marshall Islands, and the Republic of Palau.
