There are a number of factors that contribute to the overall transmission and geographic distribution of malaria. Depending of the certain factor, determines the outcome of the pattern of malaria. Climate is a major factor when looking at the causes of malaria on a global scale. Climate can be simply described as the weather conditions predominant in certain geographical areas and/or over a time period. Where malaria occurs is principally reliant on the climate. Different regions and continents around the world vary in temperatures, which is why malaria occurs in certain regions as this is the ideal temperature for mosquitos to thrive. The leading regions that cause the general pattern of malaria is tropical and subtropical regions. These…show more content…
Due to the factor of climate, the transmission rates thrive in regions when the conditions are right. For example Africa has an average temperature of 33o C, this is the ideal temperature for mosquitos and this causes a high transmission rate, relating to the concentrated pattern that follows the equator. There are many factors which prevents malaria from occurring and from that, transmission rates do not take place. In the subtropical regions, where malaria is most susceptible, mosquitos have to alter themselves to different conditions in order to bypass the obstacles where the transmission cycle will not occur. Firstly, transmission will not occur during cooler seasons such as winter as it will be less prevalent and is generally seasonal. Also deserts- excluding oases, are not at risk as the regions of Sahara and Kalahari become too dry, and also there is insufficient number of moisture which eliminates the survival of the mosquitos. Another Alternative involves countries where transmission have been intervallic through eradication. This is evident in moderate temperature areas such as Eastern Europe and the United States. The need for economic development and public health care have been met as there has been a complete eradication in malaria. The majority of countries that are at a low risk of getting malaria, are still vulnerable but with the introduction of healthcare the chances are low. This is evident when referring to malaria at a global scale as none of these
