The areola of Anopheles minimus, the principal vector of malaria in North Vietnam, occupies the entire territory of the land, except for the delta and the seacoast plains, and also mountainous localities above 700-800m in the north and 1300-1500 in the northeast. The boundaries of the territory endemic for malaria, coincide with the limits of the areola of A. minimus. The territory, endemic for malaria, was divided into 4 epidemiologically homogeneous malariogenic zones the middle mountainous river, the low mountain river, the hilly river, and the flat mountain. The middle mountain river zone is the main malariogenic zone in North Vietnam. It may be considered as the zone of independent malaria, in which all human settlements are intensive foci of this disease. The division into malariological landscapes is the best basis of a rational program for the eradication of malaria in the mountainous land with non homogeneous malaria territory.
