Urban malaria scheme is based on –
**Core Concept**
The urban malaria scheme is a public health initiative aimed at controlling and preventing malaria transmission in densely populated areas. It involves a combination of vector control measures, disease surveillance, and case management to reduce the burden of malaria in urban populations.
**Why the Correct Answer is Right**
The correct answer is based on the concept of Integrated Vector Management (IVM), which is a holistic approach to controlling vector-borne diseases like malaria. IVM involves a combination of insecticide-treated bed nets, indoor residual spraying, larval control, and personal protection measures to reduce mosquito populations and prevent malaria transmission. The urban malaria scheme is a specific application of IVM in urban settings, where the density of human population and mosquito vectors is high.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the urban malaria scheme is not based on a single intervention like bed nets alone. While bed nets are an important component of malaria control, they are not sufficient to control malaria transmission in urban areas.
**Option B:** This option is incorrect because the urban malaria scheme is not based on a single intervention like indoor residual spraying alone. While indoor residual spraying is an important component of malaria control, it is not sufficient to control malaria transmission in urban areas.
**Option C:** This option is incorrect because the urban malaria scheme is not based on a single intervention like larval control alone. While larval control is an important component of malaria control, it is not sufficient to control malaria transmission in urban areas.
**Clinical Pearl / High-Yield Fact**
A key aspect of the urban malaria scheme is the use of a combination of interventions to control mosquito populations and prevent malaria transmission. This approach is known as Integrated Vector Management (IVM), and it is a critical component of malaria control programs in urban areas.
**Correct Answer: A. IVM**
