Every year on April 25th, World Malaria Day raises awareness about a disease that continues to affect millions worldwide. At Oxymed Hospital Chennai, we're committed to educating our community about malaria prevention, symptoms, and treatment options.

What is Malaria?

Malaria is a life-threatening disease caused by Plasmodium parasites transmitted through the bite of infected female Anopheles mosquitoes. When these mosquitoes bite, they release the parasites into the bloodstream, where they travel to the liver and begin multiplying.

Key facts about malaria:

• Affects over 200 million people annually
• Caused by five species of Plasmodium parasites
• Predominantly affects tropical and subtropical regions
• Preventable and curable with prompt diagnosis and treatment

Causes of Malaria

Malaria is caused by the Plasmodium parasite, with five species known to infect humans:

1. Plasmodium falciparum - Most prevalent in Africa and the most dangerous form
2. Plasmodium vivax - Common in Asia and Latin America
3. Plasmodium ovale - Found primarily in West Africa
4. Plasmodium malariae - Widespread but less common
5. Plasmodium knowlesi - Causes malaria in macaques but can also infect humans

‍

The parasites enter the bloodstream through mosquito bites, typically between dusk and dawn when Anopheles mosquitoes are most active.

Which Type of Malaria is Most Dangerous?

Plasmodium falciparum is considered the most dangerous malaria parasite for several reasons:

• It multiplies rapidly in the blood
• Can cause severe, life-threatening complications
• Can lead to cerebral malaria (affecting the brain)
• Can cause multi-organ failure
• Has developed resistance to several antimalarial medications

Falciparum malaria requires immediate medical attention as it can progress to severe illness and death within 24-48 hours if left untreated.

Can Malaria Spread from Person to Person?

Malaria is not directly contagious from person to person like a cold or flu. The disease primarily spreads through:

• Mosquito bites from infected Anopheles mosquitoes
• Blood transfusions with infected blood (rare)
• From mother to unborn child (congenital malaria)
• Sharing needles contaminated with infected blood (very rare)

This means you cannot catch malaria by:

• Casual contact with infected individuals
• Hugging or touching someone with malaria
• Sharing food or drinks with an infected person

Malaria vs. Dengue: How to Differentiate

Both malaria and dengue are mosquito-borne diseases common in tropical regions, but they differ in several important ways:

Key differentiating factors:

• Malaria typically presents with a cyclic fever pattern with chills
• Dengue often presents with severe pain behind the eyes and a characteristic rash
• Laboratory tests can definitively distinguish between the two conditions

Symptoms of Malaria

Malaria symptoms typically appear 10-15 days after the infective mosquito bite. Initial symptoms include:

• Fever and chills (often occurring in cycles)
• Headache and muscle aches
• Fatigue
• Nausea and vomiting
• Sweating

Severe malaria, particularly from P. falciparum, may progress to:

• Cerebral malaria (brain involvement)
• Severe anemia
• Respiratory distress
• Acute kidney failure
• Hypoglycemia (low blood sugar)
• Jaundice (yellowing of skin and eyes)

‍How to Stay Safe from Malaria

Prevention is crucial in malaria control. Here are effective strategies to protect yourself:

Mosquito Control

• Use insecticide-treated bed nets
• Apply mosquito repellents containing DEET
• Wear long-sleeved clothing, especially during evening hours
• Install screens on windows and doors
• Remove standing water where mosquitoes breed

Preventive Medication

• Take antimalarial prophylaxis when traveling to endemic areas
• Follow the prescribed regimen completely
• Consult healthcare providers about the best prophylactic medication

‍

Prompt Diagnosis and Treatment

• Seek medical attention immediately if you develop fever after visiting a malaria-endemic area
• Complete the full course of prescribed antimalarial medication
• Follow-up testing to ensure complete elimination of parasites
