Focal epidemics and outbreaks due to malaria are common
in the countries of SEA Region although their reporting, verification and
response remain unsatisfactory. The prediction and response are very
important in the countries of the region because of vulnerability of areas
and populations where the transmission may not be intense but the
populations are at high risk in the member countries.
Conditions for the occurrence of epidemics and
outbreaks are very favourable. Explosive
outbreaks have been reported from Rajasthan India, while in DPR Korea the
disease has re-emerged after having been eradicated.
The epidemics are often caused by exaggerations in
seasonal variations and this is quite common. These combined with malariogenic conditions leads to epidemics as has been
the case in many epidemics in the countries of the region. Examples include
the epidemic in Menoreh hills in Indonesia, epidemics in Nepal, Bangladesh and other countries.
