Let's analyze the Assertion and the Reason:
Assertion (A): Behaviour Change Communication (BCC) is a key supportive strategy for malaria prevention and treatment under NVBDCP (National Vector Borne Disease Control Programme).
Behaviour Change Communication (BCC) plays a crucial role in public health programs, including the National Vector Borne Disease Control Programme (NVBDCP) for malaria. BCC strategies aim to promote awareness, change attitudes, and encourage the adoption of preventive behaviors such as using insecticide-treated bed nets, indoor residual spraying, and seeking timely diagnosis and treatment. Therefore, Assertion (A) is correct.
Reasons (R): People should be motivated to remain polite, earn more and spend a lot on medicines to keep themselves healthy.
Reason (R) suggests general principles for maintaining health, emphasizing politeness, financial well-being, and medical expenditure. While these factors can indirectly influence health, they are not specifically related to the strategies employed by the NVBDCP for malaria prevention and treatment. The reason does not provide a relevant explanation for the importance of BCC in malaria control programs. Therefore, Reason (R) is not correct in the context of explaining Assertion (A).
Thus, Assertion (A) is correct, but Reason (R) is not a valid explanation for it.
