The rainy season brings welcome relief from the summer heat, but it also creates ideal conditions for germs, bacteria, and viruses to thrive. High humidity, stagnant water, and poor sanitation lead to a sharp rise in infections and vector-borne illnesses.
Understanding the most common diseases during monsoon—and how to prevent them—can help you and your family stay safe and healthy.
Top Diseases to Watch Out for During the Rainy Season
1. Dengue & Malaria
Cause: Mosquito bites
Symptoms: High fever, severe body ache, headache, weakness, low platelet count
Why it spreads: Stagnant water (in buckets, pots, tyres, rooftops) becomes mosquito breeding grounds.
2. Typhoid
Cause: Contaminated food and water (especially drinking water mixed with sewage)
Symptoms: High fever, abdominal pain, loss of appetite, weakness
Bacteria involved: Salmonella Typhi
3. Viral Fever / Flu
Cause: Sudden weather changes, airborne viruses
Symptoms: Fever, cold, sore throat, body ache, fatigue
Why it spreads: Fluctuating temperatures weaken immunity.
4. Leptospirosis
Cause: Contact with rainwater contaminated with animal urine (especially rats)
Entry point: Through cuts or abrasions on skin
Symptoms: Fever, muscle pain, vomiting, red eyes
5. Stomach Infections (Cholera, Diarrhea)
Cause: Eating unhygienic, roadside or uncovered food
Symptoms: Loose motions, vomiting, abdominal cramps, dehydration
Why it spreads: Bacteria multiply rapidly in exposed, spoiled food.
6. Skin Infections & Fungal Allergies
Cause: Damp clothes, excessive sweating, lack of hygiene
Symptoms: Itching, redness, rashes, fungal patches
Common areas affected: Feet, underarms, groin area
