Full details about the 7 Most Common Rainy Season Diseases 

1. Dengue Fever – First Most Common Disease in Rainy Season

Dengue Fever is a viral illness transmitted by the Aedes mosquitoes, particularly Aedes aegypti. It is prevalent in tropical and subtropical regions around the world. A sudden onset of fever characterizes the disease and can progress to severe dengue, which includes serious complications like bleeding, organ impairment, and plasma leakage. 

Dengue poses a significant health burden, especially during the rainy season when mosquito breeding is rampant due to stagnant water.

Symptoms

• High fever
• Severe headache
• Pain behind the eyes
• Joint and muscle pain
• Nausea and vomiting
• Skin rash
• Mild bleeding (nose or gum bleed, easy bruising)

Causes

• Bite from an infected Aedes mosquito
• The virus has four serotypes (DENV-1, DENV-2, DENV-3, DENV-4)
• The mosquito breeds in stagnant water found in containers, tires, and flower pots

Treatment

• No specific antiviral treatment exists
• Supportive care: hydration, pain relief (acetaminophen), and rest
• Severe cases may require hospitalization
• Dengue vaccine (Dengvaxia) is available but is recommended only for individuals who have had a previous dengue infection

Top 10 Prevention Tips

These tips can be followed to prevent or avoid the Dengue Fever:

1. Eliminate standing water in and around your home to prevent mosquito breeding.
2. Use mosquito repellents containing DEET, picaridin, or oil of lemon eucalyptus.
3. Wear long-sleeved clothing and long pants when outdoors.

Causes

• Bite from an infected Anopheles mosquito
• Transmission of Plasmodium parasites (P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi)
• The parasites infect and destroy red blood cells

Treatment

• Antimalarial medications: Artemisinin-based combination therapies (ACTs) are commonly used
• Other medications: Chloroquine, quinine, mefloquine, and primaquine, depending on the Plasmodium species and resistance patterns
• Severe cases may require hospitalization and intravenous drug administration
• No widely available vaccine yet, but research and development are ongoing

Top 10 Prevention Tips
