The term “monsoon fever” is not a single medical condition but a common phrase often used in India. It refers to the seasonal rise of different infections during the rainy months, usually between June and September. Illnesses that fall under this umbrella include viral fever, dengue, malaria, chikungunya, and typhoid. The increased humidity, stagnant water, and mosquito breeding make the monsoon season especially risky for infections.
Here’s a detailed breakdown of what “monsoon fever” encompasses.
Why Do These Fevers Spike in Monsoon?
The monsoon climate creates ideal conditions for the spread of pathogens:
Stagnant Water: Rainwater collects in puddles, pots, tyres, and clogged drains, becoming breeding grounds for mosquitoes.
High Humidity & Temperature: This environment allows viruses, bacteria, and fungi to thrive and multiply faster.
Contaminated Water: Flooding can mix clean water sources with sewage, leading to waterborne diseases.
Poor Sanitation: Overflowing sewers and damp surroundings facilitate the spread of germs
Common Illnesses Under the “Monsoon Fever” Umbrella
The fevers are primarily categorized by how they are transmitted:
1. Mosquito-Borne Diseases (Most Common)
These are the primary culprits when people say “monsoon fever.”
Dengue: Caused by the dengue virus (spread by Aedes aegypti mosquito that breeds in clean, stagnant water).
High fever, severe headache, pain behind the eyes, muscle and joint pains (“breakbone fever”), and rash.
Malaria: Caused by a parasite (spread by Anopheles mosquito that breeds in waterlogged areas).
High fever with chills and sweating (may come in cyclical waves), headache, nausea.
Chikungunya: Caused by the chikungunya virus (also spread by the Aedes mosquito).
Sudden high fever and severe, debilitating joint pain that can last for weeks or months.
2. Water-Borne Diseases
Caused by consuming contaminated food or water.
Typhoid Fever: Caused by the bacterium Salmonella Typhi.
Sustained high fever, weakness, stomach pain, headache, constipation, or diarrhea.
Leptospirosis (Weil’s Disease): Caused by bacteria found in water contaminated with animal urine (especially rodents). Common in waterlogged/flooded areas.
High fever, severe muscle pain (especially calves), redness of eyes, headache.
Viral Gastroenteritis (Stomach Flu): Caused by various viruses like rotavirus or norovirus.
Fever, vomiting, diarrhea, stomach cramps.
3. Air-Borne & Viral Infections
The humid weather also aids the spread of viruses through the air.
Influenza (Flu): Viral infection that becomes more common.
Fever, chills, cough, sore throat, runny nose, body aches.
Common Cold: Caused by various viruses.
Mild or no fever, runny nose, sneezing, sore throat.
Key Advice for Prevention and Management
PREVENTION is the best strategy:
Stop Mosquito Breeding: Empty, cover, or turn over any containers that can hold water (coolers, pots, tyres).
Use Protection: Wear long-sleeved clothing and use mosquito repellents (creams, coils, nets).
Drink Safe Water: Consume only boiled, filtered, or purified water. Avoid street food during heavy rains.
Maintain Hygiene: Wash hands frequently with soap. Disinfect surrounding areas.
Don’t Walk in Floodwater: It may be contaminated with sewage and bacteria like leptospira.
WHAT TO DO IF YOU HAVE A FEVER:
Do NOT self-medicate. Avoid taking antibiotics (they don’t work on viruses like dengue) or aspirin/ibuprofen (they can increase bleeding risk in dengue).
Consult a doctor immediately. Proper diagnosis is crucial because the diseases have different treatments.
Get tested. Your doctor will likely recommend tests based on your symptoms (e.g., Dengue NS1, Malaria Parasite test, Typhoid test, Widal test, etc.).
Stay hydrated. Drink plenty of fluids like water, ORS, or coconut water.
Get adequate rest.
