Evaluation of malaria situation in first 3 months of 2010
Most of malaria indicators of Central Vietnam increased in March and first quarter of 2010. In March 2010,10/15 provinces had increased rate of malaria morbidity and 12/15 provinces had increased rate of malaria parasites; in the first quarter of 2010, 13/15 provinces had rate of malaria morbidity higher and 14/15 provinces had malaria parasites up. The increase of both malaria morbidity and parasites in malaria-endemic areas was in assocition with the appearance of malaria main vectors (An.minimus and An.dirus), so malaria situation became more and more complicatedly.
High malaria morbidity rates were mainly due to mobilised people (people working in the forest, sleeping in the field huts and crossing the borders). Besides, changeable weather created favourable conditions for the development of vector-borne diseases.
Although malaria situation tended to increase against the same period of last year, it was not out of control of localities, which actively conducted intensively control measures. However, the Institute need to strengthen more malaria control measures and epidemiological surveillance at high-risk areas to prevent the outbreaks from occuring.
