Solution

Reservoirs : Wild monkeys

Portals of exit : Mosquitoes

Modes of transmission : Female Aedes aegypti Mosquito bite

Portals of entry : skin and blood

Factors in host susceptibility : all humans are equally susceptible to dengue. recent research suggests that Oligoadenylate synthetases play an important role in the immune response against dengue virus. People living in dengue endemic urban areas are very susceptible.While a person who survives a bout of dengue caused by one serotype develops lifelong immunity to that serotype, there is no cross-protection against the three other serotypes.
