The rainy season in Nigeria, which typically spans from May to October, brings relief from scorching temperatures but also increases the spread of certain deadly diseases. Flooding, poor drainage systems, and stagnant water create perfect conditions for mosquitoes, bacteria, and viruses to thrive. Without proper preventive measures, outbreaks can spread rapidly, affecting thousands of people.
In this blog post, we’ll highlight five serious diseases that are currently rampant in Nigeria during the rainy season and share practical ways to protect yourself and your loved ones.
1. Malaria – The Silent Killer
Why It’s a Threat
Malaria is one of the deadliest diseases in Nigeria, and its cases spike during the rainy season due to the increase in mosquito breeding grounds. Pools of stagnant water serve as perfect habitats for the female Anopheles mosquito, which transmits the malaria parasite.
Symptoms to Watch Out For
- High fever and chills
- Sweating and fatigue
- Headaches and body aches
- Nausea and vomiting
- In severe cases, organ failure and death
How to Protect Yourself
- Always sleep under an insecticide-treated mosquito net.
- Use mosquito repellents, especially in the evenings.
- Get rid of stagnant water around your home.
- Wear long-sleeved clothing to minimize mosquito bites.
- Consider malaria prophylaxis if you’re in a high-risk area.
2. Cholera – The Waterborne Nightmare
Why It’s a Threat
Cholera outbreaks are common in Nigeria during the rainy season because floodwaters often mix with sewage, contaminating drinking water sources. Poor sanitation and inadequate access to clean water make the situation worse.
Symptoms to Watch Out For
- Severe watery diarrhea
- Dehydration and weakness
- Vomiting
- Low blood pressure
- Muscle cramps
How to Protect Yourself
- Drink only boiled or treated water.
- Wash your hands regularly with soap and clean water.
- Avoid raw or improperly cooked food, especially seafood.
- Ensure proper disposal of human waste to prevent contamination.
3. Typhoid Fever – The Silent Invader
Why It’s a Threat
Typhoid fever is caused by the Salmonella bacteria, which spreads through contaminated food and water. During the rainy season, poor drainage and flooded areas increase the risk of exposure.
Symptoms to Watch Out For
- Persistent high fever
- Abdominal pain and bloating
- Weakness and fatigue
- Constipation or diarrhea
- Loss of appetite
How to Protect Yourself
- Ensure drinking water is clean and properly treated.
- Wash fruits and vegetables thoroughly before consumption.
- Avoid street food or meals from unhygienic sources.
- Get vaccinated if you live in a high-risk area.
4. Hepatitis A – A Hidden Danger in Contaminated Water
Why It’s a Threat
Hepatitis A is a viral infection that affects the liver. It spreads through contaminated food and water, making it more prevalent during the rainy season when flooding affects clean water sources.
Symptoms to Watch Out For
- Fever and fatigue
- Nausea and loss of appetite
- Jaundice (yellowing of the skin and eyes)
- Abdominal pain
- Dark-colored urine
How to Protect Yourself
- Drink only safe, filtered, or boiled water.
- Wash your hands thoroughly after using the toilet and before eating.
- Avoid raw or undercooked shellfish.
- Get vaccinated against Hepatitis A if possible.
5. Respiratory Infections – A Hidden Threat
Why It’s a Threat
Cold, flu, and pneumonia cases tend to rise during the rainy season due to increased humidity and damp conditions, which create a breeding ground for bacteria and viruses. Poor ventilation in homes and public places also increases the spread.
Symptoms to Watch Out For
- Coughing and sneezing
- Sore throat
- Runny or blocked nose
- Fever and chills
- Difficulty breathing in severe cases
How to Protect Yourself
- Keep your home well-ventilated and free from dampness.
- Avoid close contact with people showing flu-like symptoms.
- Wash your hands regularly and use hand sanitizers.
- Boost your immune system with a healthy diet rich in vitamins.
- Consider getting a flu vaccine before the rainy season.
