Consider the following statements.

1. In tropical regions, Zika virus disease is transmitted by the same mosquito that transmits dengue.

2. Sexual transmission of Zika virus disease is possible.

Which of the statements given above is/are correct?

The correct answer is Both 1 and 2.

Let us analyze each of the given statements step-by-step:

Statement 1: In tropical regions, Zika virus disease is transmitted by the same mosquito that transmits dengue.
This statement is correct. Both Zika virus and dengue virus (along with chikungunya and yellow fever) are primarily transmitted to humans through the bite of infected mosquitoes belonging to the Aedes genus, mainly Aedes aegypti and Aedes albopictus. These mosquitoes are widely distributed in tropical and subtropical regions across the world.

Statement 2: Sexual transmission of Zika virus disease is possible.
This statement is also correct. Unlike many other vector-borne diseases, Zika virus can be transmitted sexually from a person who has the virus to their partners. The virus can remain in body fluids (including semen and vaginal fluids) for extended periods, making sexual transmission possible even if the infected person does not show symptoms at the time.

Since both Statement 1 and Statement 2 are correct, the correct option choice is Both 1 and 2.
