Monsoon Health: How to Prevent Mosquito-Borne Diseases and Support Your Immunity

Rainwater can be collected in many places around homes and buildings. Examples include:

• Open containers
• Flowerpots and trays
• Discarded coconut shells
• Buckets
• Tyres
• Construction materials
• Roof gutters
• Drainage areas
• Other objects that can hold water

When water remains stagnant, mosquitoes can use these areas to breed. This makes eliminating stagnant water one of the important steps in mosquito control during the monsoon.

Mosquitoes can transmit several infections. Two important mosquito-borne diseases discussed in the video are: Dengue Dengue is a viral infection transmitted primarily by infected Aedes mosquitoes. It can cause:

• Fever
• Severe headache
• Body aches
• Joint and muscle pain
• Nausea
• Rash

Some cases can become severe and require medical monitoring. Chikungunya Chikungunya is another mosquito-borne viral infection. It commonly causes:

• Fever
• Significant joint pain
• Joint swelling
• Muscle pain
• Headache
• Rash

Joint pain can sometimes persist even after the initial fever improves.

One of the simplest prevention strategies is to remove stagnant water. Check your surroundings regularly and:

• Empty containers holding rainwater.
• Clean water storage containers properly.
• Remove discarded objects that can collect water.
• Keep drains and gutters clear.
• Check plant pots and trays.
• Avoid leaving coconut shells and similar waste outdoors.
• Cover water storage containers.
• Keep the area around your home clean and dry where possible.

Mosquito control works best when the breeding source is removed rather than relying only on mosquito repellents.

In addition to removing breeding sites, reduce your exposure to mosquito bites. Depending on your circumstances, you can consider:

• Using mosquito repellents as directed
• Wearing clothing that covers the arms and legs
• Using window and door screens
• Using mosquito nets when appropriate
• Keeping indoor areas free from mosquito breeding sites

These measures can be particularly useful during periods of increased mosquito activity.

A balanced diet supports normal immune function, but no single food can prevent dengue, chikungunya or other infections. Instead of focusing on one "immunity-boosting" food, aim for a varied diet containing:

• Fresh fruits
• Vegetables
• Whole grains
• Pulses and legumes
• Nuts and seeds
• Adequate protein
• Sufficient fluids

Foods containing nutrients such as vitamin C, vitamin A, zinc, and protein can contribute to normal immune function when consumed as part of a balanced diet.

A practical balanced diet may include: Fruits and Vegetables Include a variety of colorful fruits and vegetables to obtain different vitamins, minerals, and other nutrients. Protein-Rich Foods Protein is important for maintaining muscles and supporting normal body functions. Depending on dietary preferences, sources can include:

• Eggs
• Fish
• Lean meat
• Milk and curd
• Dal
• Beans
• Nuts and seeds

Adequate Fluids Maintain adequate hydration, particularly if you develop fever or are losing fluids through sweating, vomiting or diarrhea. People with certain medical conditions may have specific fluid restrictions, so individual medical advice should take priority.

No. Eating a nutritious diet can support general health, but it does not provide immunity against mosquito-borne viral infections. The most effective prevention strategy is to reduce mosquito bites and eliminate mosquito breeding sites. If symptoms such as fever develop after possible mosquito exposure, medical evaluation may be appropriate.

Seek medical advice if you develop symptoms such as:

• High fever
• Severe headache
• Significant body or joint pain
• Persistent vomiting
• Rash
• Unusual bleeding
• Severe abdominal pain
• Extreme weakness
• Difficulty breathing
• Confusion or unusual drowsiness

Some symptoms require urgent medical attention. Do not attempt to diagnose dengue or chikungunya based only on symptoms because several infections can cause similar complaints.

Consult with a doctor if fever is persistent, severe, or accompanied by concerning symptoms. Medical evaluation is particularly important if there is:

• Persistent high fever
• Severe weakness
• Repeated vomiting
• Bleeding
• Breathing difficulty
• Severe abdominal pain
• Dehydration
• Altered consciousness

Early evaluation can help determine whether testing or further monitoring is required.

At Olir Super Speciality Hospital, Velachery, patients can seek medical evaluation for fever, infections and other health concerns that may occur during the monsoon season. If you develop symptoms that could be associated with dengue, chikungunya, or another infection, a doctor can assess your symptoms and determine whether further investigations are necessary. For people searching for a hospital in Chennai or a hospital in Velachery for medical care during the monsoon, timely evaluation is important when symptoms are persistent or severe.
