Infection is acquired by eating raw fish, a common food in areas of heavy endemicity. MDAs have low acceptance in areas with low malaria endemicity. Hence MDA is likely to be only used in areas with very high malaria endemicity. In 2012, MAP published the first global maps for "Plasmodium vivax" endemicity. The humidity and acidity patterns of soil are associated with endemicity. The dominant tree family in Asian rain forests, the family Dipterocarpaceae shows a special endemicity. Regional foci of endemicity are determined in part by the mosquito vectors (see Transmission). These soils have high levels of endemicity in many taxonomic groups, not least the "Nepenthes".
