How Does Malaria Spread?

Malaria Spread & Prevention: What You Need to Know 

Malaria is one of the leading causes of death in the tropical countries of Africa, South Asia, and South America. Primarily caused by the Plasmodium parasite, it thrives in hot and humid climates. Globally, malaria vaccines have been introduced in some regions to help reduce severe disease and mortality, particularly among children. However, vaccines do not cure malaria and must be used alongside other prevention and treatment measures. 

Although curable, malaria can pose a serious, life-threatening issue, like organ damage and even death, if not treated on time. Continue reading to learn about the causes and symptoms of malaria, how it spreads, and how to help prevent it. 

How is Malaria Spread? 

Malaria does not spread through mere physical contact, nor is it transmitted by cold or flu, and it is not contagious. Malaria is predominantly carried by the female Anopheles mosquito, which breeds in stagnant puddles of water. After feeding on the blood of the infected person, this mosquito transmits the parasites, causing malaria in a healthy individual. 

In very rare cases, it can also be transmitted through blood transfusion, organ transplantation, or the shared use of needles or syringes contaminated with blood.  

What Causes Malaria? 

Malaria, being a vector-borne disease, is transmitted by pathogens that are parasites. Malaria is caused explicitly by the Plasmodium parasite, which is transmitted when a female Anopheles mosquito bites a person infected with Plasmodium parasites and then bites another human. 

Generally, mosquito bites are the main cause of malaria transmission among humans, but in some rare occurrences, it may be caused by infected blood transfusions and infected organ transplantation. 

What are the symptoms of malaria? 

Malaria may seem like a commonly spread disease, but if not treated on time, it can lead to 

chronic issues, such as damage to body organs. Therefore, look for one or more of the given symptoms and seek medical attention. Listed below are the common symptoms: 

• Fatigue and weakness 
• Headache and body pain 
• Difficulty in breathing 
• Fever and high body temperature 
• Nausea and vomiting 
• Diarrhoea 
• Jaundice 

If you observe any severe symptoms, it is highly advisable to seek medical attention. To seek the best medical facilities without worrying about draining your savings on medical expenses, you can opt for health insurance that provides comprehensive medical treatment. 

Who Is at Higher Risk of Malaria? 

Malaria is a widespread vector-borne disease and common in the tropics; however, certain sections of people are more at risk than others, such as: 

• People living in poverty in the tropical region are highly susceptible to suffering from malaria, as the carrier of the vector that is the Anopheles female mosquito finds its breeding ground in a stagnant pool of dirty water. 
• Travelers from non-endemic areas (e.g., the United States, Europe) to malaria-endemic areas are highly susceptible to catching malaria because they lack any immunity. 
• People in the backwards rural areas with little to no access to healthcare are also at risk of spreading malaria, as they have no access to medical facilities. Delayed diagnosis and treatment can increase the risk of ongoing transmission in the community by allowing mosquitoes to pick up the parasite from infected individuals. 

What are the tips to prevent malaria? 

Malaria is largely caused by the bite of its carrier, the female Anopheles mosquito. Therefore, you can follow the prevention tips mentioned below to avoid getting bitten: 

• Use mosquito-repelling ointments to help you against mosquito bites. 
• Wear full-coverage clothing, such as a full-sleeved shirt, long pants, and socks, to avoid mosquito bites, especially when outdoors. 
• Use mosquito nets, as they are highly preferable, to help avoid contact with mosquitoes and reduce the risk of malaria transmission. 
• Clean your surroundings and areas near your house to prevent stagnant water bodies. Unhygienic places and stagnant water puddles serve as breeding grounds for mosquitoes, which can cause malaria. 
• To avoid developing resistance against anti-malarial drugs, it is advisable to consume medication only on the recommendation of a medical practitioner. 

Spread by the bite of an Anopheles female mosquito, malaria can be diagnosed and treated in its early stages; however, once it becomes chronic, it can result in organ damage. The best way to prevent malaria is to maintain hygiene and avoid any direct contact with mosquitoes. In case you observe any signs of malaria in your body, it is advisable to seek immediate medical attention.
