Fevers in Monsoon: Types, Symptoms, Prevention & Diagnostic Tests

Why Fevers are Common in the Rainy Season?

During rainy seasons, the rain can bring about various diseases that can cause serious health issues for you and your family members. The risk of getting infected with multiple viruses and other infections is higher in the monsoon season because of the high moisture content in the air and stagnant water that enables harmful microorganisms to thrive, eventually resulting in disease transmission. Monsoon fever is a condition where the body's temperature rises in response to the body's immune system.

Common Types of Monsoon Fevers

During the monsoon, the transmission of common types of fever occurs through four primary channels: mosquitoes, water, air, and contaminated food.

1. Mosquito-Borne Diseases

Mosquito bites introduce viruses and parasites into the bloodstream, causing mosquito-borne diseases that are transmitted through mosquito saliva. These infectious agents can pose a threat to humans, especially when stagnant water provides mosquitoes with ideal breeding conditions during the rainy season.

• Malaria: It is most common during the rainy season. Malaria is caused by a parasite called plasmodium, which enters the body through the bite of an infected Anopheles mosquito that injects malaria parasites into the bloodstream. Early diagnosis through a Malaria Antigen Test is important, as delayed treatment may result in severe health complications like cerebral malaria, renal failure, seizures, and jaundice.
• Chikungunya: It is a viral disease that gets transmitted to humans through mosquitoes infected with the Chikungunya virus. The Aedes albopictus mosquito causes chikungunya, and it breeds in stagnant water. After getting infected, individuals may experience joint and muscular pain for months at a time.
• Dengue: It is also a viral infection transmitted to humans through the Aedes species mosquito. It primarily affects the platelets in the body, and treatments should be started immediately to prevent a drop in the platelet count, which can lead to life-threatening conditions. The Dengue IgG ELISA Test helps in detecting dengue antibodies, enabling timely intervention and effective management of the disease.

2. Air-Borne Diseases

The rainy season is associated with multiple air-borne diseases such as colds, viral fever, coughs, and sore throats. These diseases are spread through the air by tiny pathogens, are mostly mild, and cause minor infections in adults. Older adults and children are more susceptible to infections during this season due to their low immune systems.

• Influenza: This viral infection is transmissible between individuals and primarily targets the throat, nose, and lungs, leading to respiratory system complications. If left untreated, it can lead to pneumonia and other chronic medical conditions such as asthma, heart disease, and diabetes.
• Cold and flu: It is also a viral infection caused by sudden fluctuations in the weather and temperatures during the rainy season. A weak immune system increases susceptibility to these minor infections. It is accompanied by a running nose, sore throat, watery eyes, fever, and chills.

3. Water-Borne Diseases

Waterborne diseases are illnesses that occur due to the presence of microscopic organisms like viruses and bacteria in water that has been contaminated. These diseases can be transmitted through the consumption of contaminated water, as well as through activities such as bathing, washing, and ingesting food prepared with contaminated water.

• Cholera: It is caused by a bacteria called Vibrio cholera. The transmission of the disease primarily takes place through the ingestion of contaminated water or food, giving rise to symptoms like dehydration and diarrhea. Severe cases can lead to electrolyte imbalances, which can cause life-threatening conditions.
• Typhoid fever: It is caused by the bacteria known as Salmonella typhi, which is transmitted through spoilt food and drinking contaminated water.
• Jaundice: It is a condition where the skin, eyes, and mucous membranes (nose and mouth) become yellow. It is due to the buildup of a chemical called bilirubin in the body. Conditions such as gallstones, hepatitis, and tumors can cause jaundice.

Precautions to Prevent Monsoon Fevers

• It is necessary to keep your body hydrated. Have herbal teas, water infused with lemon, and soups that help your body get hydrated.
• Eat foods rich in vitamin C, such as lemons, oranges, and guavas.
• Maintain personal hygiene during rainy seasons. Keep your body dry and clean. Bathe twice a day with warm water and use an antiseptic soap to kill bacteria.
• Use mosquito nets, repellant creams, and sprays before sleeping.
• Always wash vegetables and fruits, drink boiled water, cover your food, and avoid consuming outside food.
• Keep your children away from infected people and wash their hands thoroughly once they come home.

Diagnostic Test and Interpretation of Results

The qualitative detection of 8 common monsoon fevers, along with inflammatory markers, is often performed using a double multiplex PCR-based profile by real-time reverse transcriptase-polymerase chain reaction (RT-PCR). This method allows for the identification of:

• Dengue
• Chikungunya
• Malaria
• Typhoid Test
• Leptospirosis
• West Nile
• Rickettsia
• Zika Fever
• Interleukin-6 (IL-6)
• Complete Blood Count (CBC)
• Complete Urine Examination
• Fever Check

Fever Check

Regular fever checks are important for identifying high temperatures that require medical attention early. Fever checks give insights into complete well-being and immediate medical attention.

During the rainy season, the chances of contracting multiple viruses and other infections are greater. It is important to maintain good hygiene habits and seek medical advice if you experience any symptoms of fever.

Frequently Asked Questions

Why are fevers more common during the monsoon season?

Fevers are more common during the monsoon because stagnant water promotes mosquito breeding, while increased humidity and contaminated food and water encourage the spread of bacterial and viral infections.

What are the common symptoms of monsoon fever?

Common symptoms include high fever, chills, headache, body aches, fatigue, vomiting, skin rashes, dehydration, loss of appetite, and difficulty breathing. Persistent or severe symptoms require medical evaluation.

Which diseases commonly cause fever during the rainy season?

The most common monsoon-related illnesses include dengue, malaria, chikungunya, typhoid, influenza, leptospirosis, cholera, and viral fever.

Which diagnostic tests help identify the cause of monsoon fever?

Depending on your symptoms, doctors may recommend tests such as Complete Blood Count (CBC), Dengue IgG/IgM, Malaria Antigen Test, Typhoid tests, RT-PCR fever panels, urine examination, and inflammatory marker tests like IL-6.

How can I prevent monsoon fever?

You can reduce the risk by avoiding mosquito bites, drinking safe water, maintaining personal hygiene, eating freshly cooked food, eliminating stagnant water around your home, and washing hands regularly.

When should I see a doctor for a fever during the rainy season?

Seek medical attention if your fever lasts longer than 48 hours, exceeds 102°F (38.9°C), or is accompanied by severe headache, breathing difficulty, persistent vomiting, bleeding, confusion, or dehydration.

Can a Complete Blood Count (CBC) help diagnose monsoon-related infections?

A CBC can provide valuable clues by identifying changes in white blood cells, hemoglobin, and platelet counts. It is commonly used alongside disease-specific tests to help diagnose infections such as dengue, malaria, and typhoid.
