- A1 only
- B2 only
- CBoth 1 and 2Correct
- DNeither 1 nor 2
Explanation
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.
