In November 2006 by Biodiversity of Medical Arthropods in the Cuc Phuong National Park, survey on medical arthropods was conducted in the buffer zone and in the forest of the Cuc Phuong National Park. A total of 1,912 individuals of medical arthropod belonging to 157 species have been collected, including 1 species of flea (Siphonaptera), 6 species of tick (Ixodoidea), 15 species of chiggs (Trombiculidae), 16 species of mites (Gamasoidea), 73 species of flies (Brachycera) and 46 species of mosquitoes (Culicidae). They belong to 61 genus, 16 families, 3 orders (Siphonaptera, Acarina and Diptera), and 2 classes (Insecta and Arachnida). 21 species having epidemiological role were found almost all surveyed sites. The rate of biodiversity of species composition of the medical arthropods in Cuc Phuong National Park / compared to the whole country was 18,67 (This rate in Phong Nha-Ke Bang National Park was 13,40; in Cat Tien National Park was 15,37). Analysis of An.minimus s.l and An. maculatus s.l collected in the Cuc Phuong using multiplex PCR, PCR-RFLP and sequencing showed that 30% of An. minimuts s.l was An. minimus A, and 70% was An. minimus C; and two member species of An. Maculatus complex - An.maculatus and An. sawadwongporni - were present at study sites.
No vaccinations are officially required to visit. You should bring some tablets for common sickness such as headache, stomachache, diary.
There is no threat of malaria in Vietnam. But you are recommended to take Malaria tablets.
We had virtually no health problems and saw surprisingly few mosquitoes, the only real nuisance being a few of leeches in Cuc Phuong National Park. Leeches are a real pest and you can pick them up not just in the forest but also in damp grass, often when you least expect it. Although there is no complete answer to the problem, as precaution wear long trousers tucked securely into your socks and spray insect repellent liberally on your clothing and shoes! If they do get on to you, you can simply flick or pull them off. They don't leave their head in you or cause infections.
