QUESTIONCan you please tell me the high, low and no risk areas for malaria.ANSWERMalaria requires certain climatic conditions, both for its own development as well as for the survival of its vector mosquitoes. As such, malaria transmission is concentrated in lowland areas of the tropics, where there is sufficient freshwater for mosquito breeding. However, malaria can also seasonably be … [Read more...]
Distribution of Malaria
QUESTIONWhere does malaria mostly take place?ANSWERMalaria is mainly transmitted in tropical regions of the world; while some transmission does occur outside of the tropics, it tends to be seasonal in these areas (i.e. usually only during periods of high temperature/high rainfall). Within the tropics, malaria is found on all continents, though the highest number of cases is in Africa, … [Read more...]
Geographic Range of Malaria
QUESTIONHas the geographic range of malaria increased over the past 20 - 30 years? I have read that preventative measures have helped lower rates of infection, but I'm interested in the extension of the range itself.ANSWERThat is a very interesting question, and one that garners quite a lot of debate. Preventative measures have actually also helped to limit the range of malaria … [Read more...]
What countries have malaria?
QUESTIONIn which countries can it be found?ANSWERMalaria is found in many parts of Africa, Latin America, Asia, and Oceania. The exact distribution depends on climatic variables (namely heat and sufficient rainfall, for the development of the mosquitoes which transmit malaria) and also how successful a particular country or region has been at controlling malaria.For example, … [Read more...]
Malaria Distribution
QUESTIONWhat countries have malaria?ANSWERPrior to the advent of modern methods for controlling malaria, it was present on every continent in the whole except Antarctica. The transmission of malaria depends on an appropriate climate, both for the development of the parasite and the mosquitoes that it requires as a vector. This limits malaria to areas that are sufficiently warm and with … [Read more...]
Malaria in Africa
QUESTIONWhat percent of Africa has malaria?ANSWERThat is very difficult to measure, but maps of malaria transmission potential show that malaria is potentially present across most of the continent, excluding the heart of the Sahara and Kalahari deserts, and the highlands of Ethiopia, Lesotho and Uganda/Rwanda. Other parts of the continent, such as the coastline of North Africa (along … [Read more...]
Where is Malaria Found?
QUESTIONWhere is malaria found?ANSWERMalaria is found throughout the world's tropical and sub-tropical areas, and mainly in Central and South America, Africa, Asia and the Indo-Pacific region. It is most common in tropical regions, where transmission occurs year-round; in sub-tropical and temperate areas, transmission may only occur during seasons that have appropriate climatic … [Read more...]
In What Countries is Malaria Found?
QUESTIONWhat countries can malaria be found in?ANSWERMalaria is found on every continent of the world except Antartica—however, regular transmission every year mainly only occurs in Central and South America, Africa, parts of the Middle East, Asia and parts of Oceania/the Pacific Islands.The world's highest areas of malaria prevalence and transmission occur in sub-Saharan … [Read more...]
Malaria as a Global Issue
QUESTIONHow is malaria a global issue?ANSWERMalaria is a global issue because it is found all over the world, with people in 109 countries at everyday risk of infection and approximately 250 million cases every year. In fact, every year, cases of malaria are reported from every continent of the world apart from Antartica; moreover, there are concerns that in the face of climate change, … [Read more...]
Malaria Locations in Africa
QUESTION:Where in Africa is malaria mainly found?ANSWER:The distribution of malaria is constrained by two main factors: temperature and the presence of suitable mosquito hosts. These mosquitoes also depend on certain climatic conditions for their development, namely warm temperatures and sufficient rainfall to produce stagnant water, required by mosquito larvae. As such, although most … [Read more...]
