Malaria in
South East Asia Region:
South
and South eastern Asia (SEA region) harbours most cases of malaria in
the Asian continent. An estimated 1,216 million people or 70% of the
total population of SEA Region are at risk of malaria. Out of which
around 29% population at moderate to high risk of malaria, 71% are at
low risk of malaria where as remaining 30% of population free from
malaria (See
Table). About 96% of the population of
moderate to high risk of malaria in SEA Region are living in Bangladesh,
India, Indonesia, Myanmar and Thailand and contributing more than 95% of
confirmed malaria cases and deaths. During 2000-2009, in SEA Region,
malaria confirmed cases of malaria ranged between 2.16 -2.83 millions and
malaria deaths between 3188 - 6978. The proportion of P. falciparum
was between 44 – 60%.
During 2009 total 2.7 million confirmed malaria cases (Microscopically
and RDT) and 3188 malaria deaths were reported in the Region where as
estimated malaria cases were around 26 -36 million and malaria deaths
between 42300 – 77300. The P. faciparum proportion
remained around 60.5%
(including RDT positives). The highest number laboratory confirmed cases
were reported from India (1,563,344) followed by Indonesia (544,470)
and Myanmar (414,008) where as the lowest number of cases was reported
from Sri Lanka (558) followed by Bhutan(972) and Nepal(3,335). Among the population living in malarious areas,
infants, young children and pregnant women have been identified as
higher malaria risk group. Other group of people which constitute higher
malaria risk are mobile population particularly those engaged in
forest-related economy, gem-mining, fishing, industrial and road
construction work. In some countries, ethnic minorities, refugees,
displaced persons tourists and pilgrims also constitute high risk group.[4]
Malaria
situation in forest and forest related areas remains serious problem due
to highly efficient vectors, multiple-vector transmission, prolonged
transmission season, and drug-resistant P. falciparum malaria
combined with large scale and uncontrolled population movement. Forest
related malaria constitutes about 40% of total malaria cases of total
malaria cases and about 60% of the total P. falciparum cases in
the Region. As forests are becoming increasingly accessible due to the
exploitation of their natural resources, very often such population
movements result in epidemics of malaria in such areas.[4]
Several
cases of P. knowlesi, acquired from macaque monkeys, have been
reported from countries such as Malaysia, Thailand, Viet Nam,
Myanmar, and Phillippines,[5-9]
