Afghanistan
Malaria risk—P. vivax and P. falciparum—exists from May through November below 2000 m. Chloroquine-resistant P. falciparum reported.

Algeria
Malaria risk is limited. One small focus (P. vivax) has been reported in Ihrir (Illizi Department), but this is isolated and access is difficult.

Angola
Malaria risk—predominantly due to P. falciparum—exists throughout the year in the whole country. P. falciparum resistant to chloroquine and sulfadoxine–pyrimethamine reported.

Argentina
Malaria risk — exclusively due to P. vivax — is low and is confined to rural areas along the borders with Bolivia (lowlands of Jujuy and Salta provinces) and with Paraguay (lowlands of Corrientes and Misiones provinces).

Armenia
Malaria risk — exclusively due to P. vivax — exists focally from June through October in some of the villages located in Ararat Valley, mainly in the Masis district. No risk in tourist areas.

Azerbaijan
Limited malaria risk — exclusively due to P. vivax — exists from June through September in lowland areas, mainly in the area between the Kura and the Arax rivers.

Bangladesh
Malaria risk exists throughout the year in the whole country, excluding Dhaka city. P. falciparum resistant to chloroquine reported in the south-east; resistance to sulfadoxine–pyrimethamine also reported.

Belize
Malaria risk — almost exclusively due to P. vivax — exists in all districts but varies within regions. Risk is highest in the western and southern regions. No resistant P. falciparum strains reported.

Benin
Malaria risk—predominantly due to P. falciparum—exists throughout the year in the whole country. Chloroquine-resistant P. falciparum reported.

Bhutan
Malaria risk exists throughout the year in the southern belt of five districts: Chirang, Samchi, Samdrupjongkhar, Sarpang and Shemgang. P. falciparum resistant to chloroquine and sulfadoxine–pyrimethamine reported.

Bolivia
Malaria risk—predominantly due to P. vivax—exists throughout the year below 2500 m in the departments of Beni, Pando, Santa Cruz and Tarija, and in the provinces of Lacareja, Rurenabaque, and North and South Yungas in La Paz Department. Lower risk exists in Cocha-bamba and Chuquisaca. Falciparum malaria occurs in Beni and Pando, especially in the localities of Guayaramerín, Puerto Rico and Riberalta. P. falciparum resistant to chloroquine and sulfadoxine–pyrimethamine reported.

Botswana
Malaria risk—predominantly due to P. falciparum—exists from November to May/June in the northern parts of the country: Boteti, Chobe, Ngamiland, Okavango, Tutume districts/sub-districts. Chloroquine-resistant P. falciparum reported.

Brazil
Malaria risk — P. vivax (79%), P. falciparum (21%) — is high throughout the year in most forested areas below 900 m within the nine states of the "Legal Amazonia" region (Acre, Amapá, Amazonas, Maranhão (western part), Mato Grosso (northern part), Pará (except Belém City), Rondônia, Roraima and Tocantins. Transmission intensity varies from municipality to municipality, but is very high in jungle areas of mining, lumbering and agricultural settlements less than 5 years old where multidrug-resistant P. falciparum strains are common (> 50%). Intensity of transmission is lower in urban areas, including in large cities such as Pôrto Velho, Boa Vista, Macapá, Manaus, Santarém and Maraba. In the states outside "Legal Amazonia", malaria transmission risk is negligible or non-existent.

Burkina Faso
Malaria risk — predominantly due to P. falciparum — exists throughout the year in the whole country. Resistance to chloroquine reported.

Burundi
Malaria risk — predominantly due to P. falciparum — exists throughout the year in the whole country. Resistance to chloroquine and sulfadoxine-pyrimethamine reported.
