The study was conducted from 2002‐2004 in 3 industrial crop areas: rubber, coffee, cashew of Gia Lai province, with 2 objectives: Assess some epidemiological characteristics of malaria in the community living in industrial crop areas and identify some factors affecting the level of malaria in these industrial crop areas. With a cross‐sectional study design and analysis, the following results were obtained:
The study was conducted from 2002‐2004 in 3 industrial crop areas: rubber, coffee, cashew of Gia Lai province, with 2 objectives: Assess some epidemiological characteristics of malaria in the community living in industrial crop areas and identify some factors affecting the level of malaria in these industrial crop areas. With a cross‐sectional study design and analysis, the following results were obtained:
The rate of malaria parasite infection at peak 2 (9‐11) was higher than peak 1 (4‐5) in all 3 regions. The infection rate was in the rubber region (8.59%), coffee region (7.50%), and cashew region (5.99%). P.falciparum accounted for the majority of malaria parasites in the rubber region (82.05%), coffee region (72.72%), and cashew region (74.00%).
In the rubber area, there are 17 species (including An.minimus and An.dirus); in the coffee area, there are 14 species (including An.minimus and An.dirus); in the cashew area, there are 16 species (only 1 main species, An.minimus, was collected). An.minimus bites blood from 8pm to 1‐2am, with the highest biting rate from 10‐11pm at night. In the rubber area, An.minimus continues to bite blood until 4‐5am with a density of 0.5 individuals/hour/person. An.dirus bites blood from 9‐2pm at night, lasting until 2‐3am, with the highest biting rate at 10‐11pm at night.
Sociological surveys show that people believe that sleeping under mosquito nets can prevent malaria, but health workers have not proactively approached the community to provide health care. People also request to provide free mosquito nets (coffee, cashew) or sell them at subsidized prices and train village health workers to provide direct health care in the community.
In rubber areas, latex tappers are more likely to contract malaria than other groups. Communities living near streams, rubber forests, and coffee gardens have a higher rate of malaria than others.
