- Mosquito- and malaria-related deaths and rates from both IHME and WHO are statistically derived estimates rather than actual real-world tallies. Differences in estimates from one source to another are likely due to differences in methodology, such as data tabulation and/or statistical computations used.
- WHO rates are given as a range at the source. The high and low ends of that range are also shown.
- Mosquito deaths by country are largely synonymous with Malaria Deaths by Country.
- Mosquito- and malaria-related deaths are highest in countries with dense mosquito populations and lowest in countries without mosquitos
Snapshot
-
Malaria accounts for the vast majority of mosquito-related deaths worldwide, despite being both preventable and treatable.
-
In 2023, Nigeria recorded the highest estimated number of mosquito-related (malaria) deaths at roughly 216,700, followed by the Democratic Republic of the Congo at about 75,000.
-
Some smaller countries experience extreme malaria death rates, such as Sierra Leone (131.15 per 100K) and Niger (115.86 per 100K), despite having far fewer total malaria deaths than larger countries like Nigeria.
While mosquito bites account for only a small share of global deaths, they remain a major public health threat in parts of Sub-Saharan Africa. In 2023, malaria-related deaths—responsible for the vast majority of mosquito-transmitted fatalities—were heavily concentrated in a small number of countries, led by Nigeria and the Democratic Republic of the Congo.
Mosquito-Related Deaths Attribution Most deaths attributed to mosquito bites reflect malaria fatalities, as malaria accounts for the vast majority of mosquito-transmitted deaths globally.
Countries With the Highest Mosquito-Related (Malaria) Deaths
In terms of total deaths, mosquito-related fatalities are overwhelmingly concentrated in a small number of countries with large populations and widespread malaria transmission. In 2023, Nigeria recorded the highest estimated number of mosquito-related (malaria) deaths worldwide, at roughly 216,700.
The Democratic Republic of the Congo followed with about 75,000 deaths, while Niger reported approximately 30,900. Several other Sub-Saharan African countries also experienced substantial mortality, including Cameroon (28,200), Ivory Coast (27,300), and Uganda (25,400). Together, these countries account for a large share of the global mosquito-related death burden.
Countries With the Highest Mosquito-Related (Malaria) Death Rates
When measured by death rates rather than total counts, a different pattern emerges. Smaller countries can experience far greater individual risk even if their overall death totals are lower.
In 2023, Sierra Leone recorded the highest estimated mosquito-related (malaria) death rate in the world, at 131.15 deaths per 100,000 people, followed by Niger (115.86) and Burundi (90.82). Other countries with exceptionally high rates included Benin (89.24), Nigeria (88.52), and Burkina Faso (87.05), reflecting intense malaria transmission combined with limited access to healthcare.
