Question 31
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?
AOptions
BSolution
Statement 1 is correct. The Zika virus is primarily transmitted to humans through the bite of an infected Aedes species mosquito, particularly Aedes aegypti. This is the same mosquito species that transmits other tropical diseases like dengue, chikungunya, and yellow fever. Statement 2 is correct. While mosquito bites are the primary mode of transmission, sexual transmission of the Zika virus has been documented. The virus can persist in semen for a longer period than in blood, making sexual transmission possible from an infected person to their partner.
CStrategy
For science and technology questions, especially those related to diseases, understand the primary modes of transmission, causative agents, and major associated symptoms. Pay attention to common misconceptions or less obvious modes of transmission.
