Which one of the following measures would be least effective in controlling the spread of Zika virus? A - VCE - SSCE Biology - Question 34 - 2023 - Paper 1

Providing free face masks and encouraging their use in public would be the least effective measure in controlling the spread of the Zika virus. Zika is primarily transmitted by infected mosquitoes, and wearing masks does not prevent mosquito bites. Although masks can protect against the virus in situations where individuals are already infected, they do not address the root cause of transmission through mosquito vectors. In contrast, educational campaigns, quarantining infected individuals, and wearing protective clothing directly target ways to minimize exposure to mosquitoes and prevent further spread.
