Why is malaria an environmental disease?

An efficient system for malaria transmission needs strong interaction between humans, the ecosystem and infected vectors. Global warming induced by human activities has increased the risk of vector-borne diseases such as malaria.

Is malaria an environmental disease?

Environmental factors affect the transmission intensity, seasonality, and geographical distribution of malaria, and together with the vector, the human, and the parasite compose the malaria system.

What environmental issues can cause malaria?

These are poor drainage system, poor sullage disposal, open blocked drains, water logging, indoor water storage in open containers and presence of anopheles mosquitoes inside and outside their homes coupled with lack of health knowledge, lowered resistance due to malnutrition have been some of the predisposing causes …

How malaria spreads in our surroundings?

Malaria spreads when a mosquito becomes infected with the disease after biting an infected person, and the infected mosquito then bites a noninfected person. The malaria parasites enter that person’s bloodstream and travel to the liver. When the parasites mature, they leave the liver and infect red blood cells.

Is malaria an epidemic?

Yet despite the fact that HIV and AIDS, tuberculosis, and malaria still kill millions of people each year across multiple countries and regions, these diseases are no longer talked about as pandemics, but are generally called epidemics, or endemic diseases.

Why is malaria in tropical areas?

Malaria typically is found in warmer regions of the world — in tropical and subtropical countries. Higher temperatures allow the Anopheles mosquito to thrive. Malaria parasites, which grow and develop inside the mosquito, need warmth to complete their growth before they are mature enough to be transmitted to humans.

How does malaria affect economic development?

Once seen as a consequence of poverty, malaria is now regarded as one of its causes. Experts say malaria slows economic growth in Africa by up to 1.3 percent per year. Rural and poor people are especially at risk because they are least likely to have the means to prevent and treat malaria.

How does climate change affect environmental health?

Climate change affects the social and environmental determinants of health – clean air, safe drinking water, sufficient food and secure shelter. Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.

What are the social causes of malaria?

Various socio-demographic factors, such as ethnic groups, parents’ education levels and occupation, use of personal protective measures and family living standards are important risk factors for malaria transmission and epidemics [16].

Is malaria caused by bacteria?

A: Malaria is not caused by a virus or bacteria. Malaria is caused by a parasite known as Plasmodium, which is normally spread through infected mosquitoes.

What is malaria epidemiology?

Malaria occurs primarily in tropical and some subtropical regions of Africa, Central and South America, Asia, and Oceania. There is tremendous geographic variation in intensity of transmission and risk of infection. Human malaria is caused by one or more parasites: Plasmodium falciparum, P. vivax, P. ovale, or P.

What is the name of the protozoan that causes malaria?

Malaria is a protozoan infection of the red blood cells, transmitted by the bite of a female anopheles mosquito. Malaria is caused by the protozoa of the genus Plasmodium.

What are the 4 diseases in pandemic?

Major pandemics and epidemics such as plague, cholera, flu, severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have already afflicted humanity. The world is now facing the new coronavirus disease 2019 (COVID-19) pandemic.

Why is there no malaria in Europe?

Malaria was eradicated from Europe in the 1970s through a combination of insecticide spraying, drug therapy and environmental engineering. Since then, it has been mostly imported into the continent by international travellers and immigrants from endemic regions.

Why is malaria common Africa?

Africa is the most affected due to a combination of factors: A very efficient mosquito (Anopheles gambiae complex) is responsible for high transmission. The predominant parasite species is Plasmodium falciparum , which is the species that is most likely to cause severe malaria and death.
