The Man Biting Rate (MBR) in malaria vector surveillance is calculated as:

  • A Number of mosquitoes biting one person per night (catches per person per night)
  • B Number of mosquitoes caught per trap per hour
  • C Proportion of blood meals taken on humans vs animals
  • D Number of infective bites per person per year
Correct answer: A. Number of mosquitoes biting one person per night (catches per person per night)

Explanation

Man Biting Rate (MBR) = Average number of anopheline mosquitoes biting one person per night, measured by human landing catches. Entomological Inoculation Rate (EIR) = MBR × Sporozoite rate (number of infective bites per person per night/year). Human Blood Index (HBI) measures proportion of blood meals from humans.
