Malaria transmission occurs through Plasmodium species-infected mosquitoes. Know about the malarial species in India.
Malaria is a serious disease that spreads by mosquitoes infected with Plasmodium parasites. If untreated, malaria can cause seizures, brain damage, trouble breathing, organ failure and death. In this article, you would come to know the types, causes, diagnoses and treatments available for malaria in India.
Malaria is a tropical disease and it is more pronounced in hot humid climate conditions. In 2020, there were 241 million reported cases of malaria globally with the highest cases being in Africa and South Asia. The main areas affected by malaria include,
Africa
Islands in the Central and South Pacific Oceans (Oceania)
Central and South America
Eastern Europe
South and Southeast Asia
Dominican Republic, Haiti and other areas in the Caribbean
Though many species of Plasmodium can cause malaria, the common species that are found in India are,
1. Plasmodium falciparum
2. Plasmodium malaria
3. Plasmodium vivax
4. Plasmodium ovale
Of all the species, P. falciparum is the deadliest.
Malaria transmission is initiated by the female Anopheles mosquito. Mosquitoes like Anopheles suck human blood for egg production. The natural cycle of malaria involves cyclical infection of humans and female Anopheles mosquitoes.
Humans get infected when a plasmodium parasite-infected mosquito bites them. The parasite is then released into their blood when a mosquito bites them. After infection, they grow and multiply first in the liver cells and then in the red cells of the blood, leading to the breakage of the intact cells. The parasites growing inside the red blood cells release parasites that continue the cycle by invading other red cells.
The blood-stage parasites cause the symptoms of malaria in humans. However, when these forms of parasites are ingested by a female Anopheles mosquito, they begin a cycle of growth and multiplication in the mosquito, which takes the form of the parasite called a sporozoite and migrates to the mosquito’s salivary glands.
Now, when the Anopheles mosquito sucks the blood from another human, they transfer the sporozoites, which then migrate to the liver, ultimately beginning a new cycle.
Here is the malaria map which demonstrates the life cycle of the mosquito and plasmodium species,
These are some of the common causes of malaria,
Living in unsanitary conditions and a tropical climate
A pregnant mother having malaria can transmit it to the child
Careless blood transfusions
Organ donations
Shared hypodermic needles
Malaria symptoms usually occur from 10 days to one month after the infection from a mosquito. Often, signs and symptoms of malaria are similar to the flu. They are,
Fever and shaking chills
Profuse sweating
Headache and muscle aches.
Fatigue
Chest pain and cough.
Diarrhea, nausea and vomiting.
In extreme cases of malaria, it can cause,
Jaundice
Anaemia
Cerebral malaria (may progress to coma)
Medical professionals would examine you for the symptoms and enquire about your travel history. By taking a sample of your blood, they can test whether you have malaria by analyzing it for malarial parasites. send it to a lab to see if you have malaria parasites. In the case of a malarial infection, your medical care provider would choose an appropriate treatment.
Malarial infections are often treated with anti-malarial drugs which can kill the parasites. Some of the common antimalarial drugs are,
Artemisinin drugs (artemether and artesunate)
Atovaquone Chloroquine
Doxycycline
Mefloquine
Primaquine
Quinine
Antimalarial drugs can cause various side effects and interfere with your normal body functions by causing various side effects,
Seizures
Anaemia
Psychology issues
Decreased vision
Headaches
Ringing in the ears (tinnitus)
Gastrointestinal problems
Increased sensitivity to light
Sickle cell anaemia is a blood disorder where the red blood cells are sickle-shaped providing no room for the malarial parasite to complete the life cycle. This blood disorder provides natural protection to people from malaria. More research is going on to apply this phenomenon to curb malarial infections.
Here are the tips that can help you in staying away from malarial infections.
Apply repellents to the skin that is exposed to the environment.
Sleep with mosquito nets during the night.
Have screens on your windows and doors.
Treat clothing, mosquito nets, tents, sleeping bags and other fabrics with Use insect repellents like permethrin on clothes, mosquito nets, tents and sleeping bags.
Sleep with long pants and long sleeves to avoid exposing your skin to mosquito bites.
Malaria is caused by the Plasmodium species spread by the vector female Anopheles mosquito.
The common species of malaria in India are Plasmodium falciparum, Plasmodium malariae, Plasmodium vivax, and Plasmodium ovale.
Fever, shaking chills, headache, muscle aches, and tiredness are some of the primary symptoms of malaria.
Cerebral malaria can lead to coma and has the highest probability of causing mortality.
After blood tests give positive results for malaria, you will be treated with antimalarial drugs.
Though all four types of malaria are common, Plasmodium vivax is the most common type of malaria in India.
Plasmodium falciparum, Plasmodium malariae, Plasmodium vivax, and Plasmodium ovale are the 4 species of malaria that cause human infection.
There are usually 4 stages of malaria - they are sporozoite stage, liver stage, blood stage and sexual stage.
Fever, shaking chills, headache, muscle aches, and tiredness are some of the common symptoms of malaria.
Though there is malaria risk all over India, infection rates in the northeastern states are more pronounced.
Yes! Malaria remains one of the major public health problems.
The foremost cause of malaria remains the lack of sanitation and the stagnation of sewage waters.
High-level sewage water treatments, proper waste disposal, and mosquito repellents can keep you away from malaria.
Malaria rapid diagnostic tests diagnose malaria by detecting evidence of malaria antigens in human blood.
Plasmodium falciparum is the deadliest of all other malarial infections.
Liver failure, jaundice, a sudden drop in blood pressure, pulmonary oedema, acute respiratory distress syndrome (ARDS), low blood sugar, kidney failure and rupturing of the spleen are some of the common complications of malaria.
Northeast states and southern states like Andhra Pradesh have the highest cases of malaria.
Though there are few advancements made in the malaria vaccine, there aren't still any effective vaccines.
