Q1. 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?
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?
Explanation
Statement 1 is correct: The Zika virus is primarily transmitted by the Aedes aegypti mosquito which is also the primary vector for dengue fever. This mosquito species thrives in tropical and subtropical regions, making it a common carrier for both diseases. The Aedes aegypti mosquito is well-adapted to urban environments and breeds in stagnant water, such as in containers, flower pots, and discarded tires.
Statement 2 is correct: Zika virus can be transmitted through sexual contact unlike other mosquito-borne diseases like dengue or chikungunya. The virus can remain in semen for an extended period even after symptoms have resolved. Zika virus infection during pregnancy can cause severe birth defects such as microcephaly.
