Common rainy season diseases
, their symptoms and prevention
Dengue Fever
Cause: Spread by Aedes mosquitoes that breed in stagnant water
Symptoms: High fever, severe body pain, rashes, weakness
Dengue fever is a viral infection transmitted by a mosquito that thrives on standing water available during the monsoon.
Sudden onset of high fever with intense body and joint pain are typically the first signs. Soon after, skin rashes and intense weakness develop. Immediate medical care and adequate hydration are needed to prevent developing complications of dengue hemorrhagic fever.
How to protect yourself:
Remove standing water around the house (flowerpot, coolers, buckets).
Employ mosquito repellants and use full-sleeved clothing.
Sleep in bed nets against mosquitoes.
Keep windows and doors screened or closed at dawn and dusk.
Malaria
Cause: Transmitted by Anopheles mosquitoes due to Plasmodium parasites
Symptoms: Chills, sweating, fever, vomiting
Malaria is another mosquito-borne disease that culminates in rainy seasons. The parasites are inoculated into the blood by bites from mosquitoes, and they create cyclical fever patterns accompanied by chills and vomiting.
Precautionary measures like sleeping under a mosquito net, applying repellents, and keeping the place clean and free from standing water can reduce risk to a large degree.
How to protect yourself:
Use insecticide-treated bed nets.
Spray mosquito repellents indoors and outdoors.
Stay indoors during peak mosquito hours.
Maintain proper drainage to avoid mosquito breeding.
Leptospirosis
Cause: Bacterial infection from water with animal urine
Symptoms: Fever, muscle pain, red eyes
Leptospirosis occurs when you come into contact with urine-tainted water from infected animals, especially in floods. It produces flu-like symptoms like fever, body pain, and conjunctivitis (red eyes). Avoid wading through floodwaters, practice good hygiene, and consult a doctor if symptoms appear.
How to protect yourself:
Do not walk through standing or contaminated water.
Use protective footwear in heavy rain or cleaning.
Practice hygiene and wash feet clean after exposure.
Keep rodents out of your home and environment.
Chikungunya
Cause: Viral infection transmitted by mosquitoes
Symptoms: Fever, severe pain in the joints
Chikungunya is dengue-like but distinguished by prolonged arthritis-like joint pain. It is transmitted by the same mosquitoes that transmit dengue and most often causes acute fever with blinding joint inflammation. Rest, fluids, and pain control assuage symptoms in the absence of antiviral medication.
How to protect yourself:
Prevent bites from mosquitoes through repellents and screens.
Eliminate breeding sites such as uncovered water tanks.
Wear arms and legs covers when stepping outside.
Clean water storage vessels regularly.
Typhoid Fever
Cause: Spread by contaminated food and water
Symptoms: Prolonged fever, weakness, pain in the abdomen, constipation
Typhoid is a life-threatening bacterial infection that is common during monsoons due to poor sanitation. It causes prolonged high fever, abdominal pain, and gastrointestinal issues like constipation.
Prevent typhoid by practicing food hygiene, drinking purified water, and taking the vaccine in risk-affected areas.
How to protect yourself:
Drink only purified or boiled water.
Avoid raw salads, street food, and unclean restaurants.
Wash hands with soap thoroughly before eating.
Vaccinate in exposed areas.
Cholera
Cause: Eating contaminated food or water containing Vibrio cholerae bacteria
Symptoms: Severe diarrhea, dehydration
Cholera is an acute diarrheal illness that can result in sudden dehydration and death if not treated. It usually results from water or food contaminated with the illness in dirty environments. Oral rehydration therapy promptly is crucial for recovery, alongside water safety and sanitation measures.
How to protect yourself:
Drink only filtered, clean, or boiled water at all times.
Keep yourself clean and dispose of waste safely.
Wash hands often, particularly after using the toilet.
Avoid consuming raw or undercooked food.
Hepatitis A
Cause: Viral infection via contaminated water or food
Symptoms: Jaundice, fatigue, nausea, pain in the abdomen
Hepatitis A is an infection of the liver caused primarily by drinking contaminated water or food. The symptoms include jaundice, weakness, and gastric disturbance. Vaccination and proper sanitation practices are the best ways to prevent infection.
How to protect yourself:
Avoid consuming food from dirty food stalls or hawkers.
Eat neatly cooked food and clean water.
Wash vegetables and fruits thoroughly.
Immunization is strongly advised in endemic areas.
Common Cold and Flu
Cause: Viral infection caused by the temperature and humidity
Symptoms: Sore throat, sneezing, cough, fever
Monsoon weather promotes the spread of respiratory viruses, and a greater number of people get colds and flu. The symptoms are typically mild but cause inconvenience.
Rest, excessive fluid intake, and proper hygiene measures, including frequent hand washing, allow for rapid recovery.
How to protect yourself:
Do not be in close contact with affected persons.
Strengthen your immunity through a balanced diet and fluids.
Cover mouth with tissues or the elbow while coughing/sneezing.
Keep your environment clean and dry.
Fungal Infections
Cause: Fungi that thrive in damp environments
Symptoms: Itchy scaly lesions on skin; athlete's foot; ringworm
The rainy season's humid weather is an ideal environment for fungal skin and nail infections. Fungal infections like athlete's foot and ringworm are common in this category. Keeping the skin dry, wearing loose clothing, and using antifungal creams or powder prevent and treat these infections.
How to protect yourself:
Dry the skin and dress in breathable clothes.
Immediately change out of wet clothing.
Apply antifungal powders or creams if susceptible to infection.
Avoid sharing towels, socks, or shoes.
Gastroenteritis
Cause: Bacterial or viral infection through contaminated food or water
Symptoms: Diarrhea, vomiting, stomach cramps
Gastroenteritis causes inflammation of the stomach and intestines and results in vomiting and diarrhea. It is usually picked up through unhygienic food preparation or drinking contaminated water. Proper food hygiene and hydration are needed to avoid the most serious complications.
How to protect yourself:
All food must be freshly prepared and cooked.
Don't consume exposed food from street vendors.
Keep food in clean, cover containers.
Keep drinking water clean and don't consume ice from unknown sources.

Summer sets the trap: Doctors call for pre-monsoon malaria vigilance
As summer sets in, doctors warn that heat, stagnant water and increased outdoor exposure are driving malaria risks higher. With the WHO flagging seasonal shifts and behavioural patterns as key contributors, timely prevention and awareness can help avert pre-monsoon outbreaks. read more As temperatures rise across India, health experts are raising alarms over malaria transmission during summer, an often-overlooked seasonal danger. While monsoon months are traditionally linked to vector-borne diseases, medical experts say that summer lays the groundwork for intensified malaria outbreaks, creating perfect conditions for the Anopheles mosquito, the vector of the Plasmodium parasite. Firstpost talked with Dr Satish Koul, Senior Director & Unit Head, Internal Medicine, Fortis Memorial Research Institute (Gurugram) and Dr Tushar Tayal, Consultant, Internal Medicine, CK Birla Hospital, Gurugram to understand how summer conditions increase malaria risk and what people can do to protect themselves. STORY CONTINUES BELOW THIS AD 'The summer heat, combined with pre-monsoon showers, speeds up the parasite's development inside mosquitoes. It also increases outdoor exposure and water accumulation—both major contributors to malaria risk.' How summer creates a perfect storm According to the World Health Organisation (WHO), malaria is a preventable and treatable disease, but still poses a grave threat, especially in tropical and subtropical regions. The rising summer temperatures (especially between 20–30°C) are ideal for both mosquito survival and the Plasmodium parasite's incubation. Dr Tayal said 'Improper drainage, stagnant water in coolers, gutters, and discarded containers—all typical during Indian summers—become prime mosquito breeding sites, especially in areas with poor sanitation.' Adding to the risk is human behaviour—greater outdoor activity during evenings and early mornings coincides with peak Anopheles mosquito biting times. In regions where people lack access to bed nets, mosquito repellents, or screened housing, exposure increases dramatically. High-risk populations and delayed diagnosis Children, pregnant women, the elderly, and those with chronic illnesses or compromised immunity are particularly vulnerable. Dr Koul pointed out that heat-related dehydration and fatigue can further impair the body's immune response, making infections more severe. What complicates detection is that early malaria symptoms—fever, body aches, chills—closely mimic heat exhaustion and viral fevers. In rural or underserved communities, this often leads to delayed treatment or reliance on self-medication, heightening the risk of complications and community-level spread. Seasonal mobility and travel risk Summer holidays often see increased travel to forested or rural areas—many of which are malaria-endemic zones. According to Dr Tayal, 'Travel to such locations without prophylaxis or awareness increases the chances of contracting the disease. Migrant labour movement can also contribute to new outbreaks.' Clinical advice for prevention Both experts stress proactive prevention as key. Recommendations include: Eliminating stagnant water from all containers weekly. Using insecticide-treated bed nets and mosquito repellents consistently. Wearing protective clothing in the evenings and early mornings. Seeking medical attention promptly for any unexplained fever or flu-like symptoms. STORY CONTINUES BELOW THIS AD Consulting a physician for antimalarial prophylaxis if traveling to endemic areas. Climate Change and Future Outlook Climate change adds another layer of complexity. With rising temperatures and unpredictable rainfall, malaria zones may expand and transmission seasons may lengthen. As such, community awareness, infrastructure improvements, and preventive care must be at the forefront of India's malaria strategy. As the summer heat intensifies, experts warn that tackling malaria requires not just monsoon vigilance but year-round, seasonally adaptive public health action.

Unmaintained open sites in twin cities pose danger to public health
Hubballi: Open sites in twin cities of Hubballi-Dharwad have emerged as a major concern for public health and safety. These neglected plots have turned into breeding grounds for mosquitoes and shelters for stray animals. The unchecked growth of wild vegetation in these areas has led to the formation of mini-jungles within residential zones, posing difficulties for safe movement. As per Hubballi-Dharwad Municipal Corporation (HDMC) records, there are 1,30,000 open sites in the city, many of which are contributing to hygiene and security issues in localities. The uncontrolled growth of vegetation in these sites has created mini-jungles within residential areas, making it difficult for residents to move safely around their neighbourhoods. HDMC has begun taking measures to address this issue following the directive from district minister Santosh Lad. The civic body will now issue formal notices to site owners, requiring them to clear and maintain their properties. The owners will have a week to comply with these notices. The HDMC has outlined a three-step enforcement plan. Firstly, owners who fail to respond to initial notices will face substantial monetary penalties. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Forget Furosemide, Use This Household Item To Help Drain Edema Fluid WellnessGuide Learn more Undo Secondly, if the sites remain uncleaned despite the fines, the authorities will undertake the cleaning work and charge the expenses to the owners. Finally, in cases of continued non-compliance, the municipal corporation has been authorised to acquire these plots. Local residents have welcomed this initiative, as these neglected sites have been causing various problems, including increased incidents of dengue and Chikungunya. The presence of stray animals has also led to safety concerns, particularly for children and elderly residents in these areas. The municipal authorities have started mapping these sites and creating a database of property owners. They will also conduct regular inspections to ensure sustained compliance with cleanliness standards. This systematic approach aims to transform these problematic spaces into well-maintained areas that contribute positively to the urban landscape of the twin cities. Ashok Kumar, a resident of Gokul Road, said the open plots have become overgrown with vegetation, transforming residential areas into breeding grounds for mosquitoes and providing refuge for stray dogs, cattle, and pigs. The authorities should initiate stern action against the owners of the land. Rudresh Ghali, commissioner, HDMC, mentioned that district minister Santosh Lad recently gave instructions for strict action against open sites. He stated that they will begin proceedings against open sites and have instructed all zonal officials to gather information about open site owners and send them notices. He also indicated that if owners do not comply, they will conduct an extensive open sites cleaning operation, with the expenses being recovered from site owners during property tax collection.
