Malaria Needs Your Attention: Know About Its Symptoms, Causes and Treatment
What is malaria? Malaria is caused because of mosquitoes that are infected with tiny parasites. When an infected mosquito bites your body, it injects malaria parasites into the blood. This serious disease is caused by parasites and not because of viruses or bacteria. If not treated properly, malaria can lead to several health issues like seizures, difficulty in breathing, brain damage, organ failure or even death. If you are travelling to an area where malaria is common, you must consult your doctor regarding the ways you can protect yourself from this disease. This infection can also spread when a malaria mosquito bites a malaria patient and then bites a non-infected person. How common is malaria? Tropical areas are more prone to malaria as a hot and humid climate is favourable for this disease. In 2020, around 241 million patients were reported throughout the world, with 627,000 deaths due to this disease. Most of these cases were reported in Africa and South Asia. Where does malaria usually occur? Malaria can spread all over the world and is much more common in developing countries and areas where the temperature is humid and warm.

People with financial crises or who don't have access to proper treatment are more likely to develop complications from this disease. What causes malaria? When a mosquito bites a malaria patient, it becomes infected with the disease. When this mosquito bites another person, it transfers the parasite into that person's bloodstream. This results in the multiplication of parasites. There are 5 types of malaria parasites which can infect us. Usually, malaria transmission happens through the infected bites of female Anopheles mosquitoes. It can also be spread through contaminated needles. The transfer of malaria disease from a pregnant lady to her newborn before or during birth is very rare. It is unlikely but sometimes possible for malaria to get transferred through blood transfusions, hypodermic needles, and organ donations. What are the signs and symptoms of malaria?

The high severity of malaria may lead to coma, which is called cerebral malaria. Such a condition shows 15% of deaths in children and 20% of deaths in adults. When do symptoms begin if you're infected with malaria? It takes around 10 days for a malaria infection to show in your body. As per the parasite type, symptoms of malaria in children or adults can be mild or severe. Some patients may feel sick for around a year after the mosquito bites them. Some parasites remain in the body for several years without showing major symptoms. Some types of malaria, depending on the parasite, may repeat after a certain period.
