As the monsoon season rages over portions of Asia, Africa, and tropical America, bringing relief from summer heat, it also opens the floodgates literally to a range of health issues. Foremost among them are waterborne diseases that peak during this time and constitute a major threat to public health, particularly in such nations as India where monsoon cycles are intense and clean water access infrastructure is patchy at best.Waterborne infections that peak during monsoons, their symptoms, how they are spread, and above all, how to avoid them. If you live in a flood area or just want to ensure the well-being of your loved ones during the rains, this is your go-to monsoon health manual.Link Between Monsoons and Waterborne IllnessesMonsoons, which are characterized by heavy rains, tend to flood drainage systems, commingle sewage with fresh water, and cause water supply contamination. Poor sanitation, when coupled with high humidity, becomes a breeding ground for viruses, parasites, and bacteria. Drinking, bathing, or exposure to such polluted water transmits numerous diseases, the majority of which are associated with the gastrointestinal tract, liver, or skin.1. CholeraCaused by the bacterium Vibrio cholerae, cholera is an epidemic disease that is characterized by profuse watery diarrhea and dehydration. Left untreated, it is even lethal, especially for children and the elderly. Tainted drinking water is the major offender.Use only purified water—ideally filtered through RO (reverse osmosis), UV, or multi-stage filtration systems. Boiling water before drinking is still one of the cheapest and best methods.2. DysenteryDysentery, mistakenly referred to as stomach flu, is a severe bacterial infection due to Shigella or E. coli. It causes bloody diarrhea, cramps, nausea, and dehydration. Unhygienic food or water intake and poor sanitation are the leading causes.Dysentery is still one of the foremost causes of death among children under the age of five in low-income countries.3. TyphoidCaused by Salmonella Typhi, typhoid fever is bacterial in nature and is transmitted by contaminated food and water. It has symptoms that include continuous high fever, weakness, constipation or diarrhea, and pain in the stomach.Typhoid, according to WHO, infects 11–20 million people worldwide every year. It can be prevented by vaccination and drinking clean water.4. GiardiaThis lesser known parasitic infection is caused by Giardia lamblia. When ingested, the parasite can live in the human intestine for years and cause bloating, gas, greasy stools, and heavy weight loss.Giardia is prevalent even in industrialized countries with wilderness activity, swimming pools, or day care centers as potential sources.5. Hepatitis AHepatitis A, which is an infection of the liver by a virus, is very infectious and transmitted through eating contaminated food and water. It presents itself with jaundice, weakness, nausea, and fever.Vaccination is effective for several years. Safe food and water hygiene must be practiced.6. Viral GastroenteritisCommonly referred to as the "stomach flu," viral gastroenteritis runs amok during monsoons. It infects the stomach and intestines, causing vomiting, diarrhea, and abdominal cramps. Norovirus and rotavirus are common culprits.Infants and children are particularly susceptible. Get them vaccinated and give them plenty of fluids to avoid dehydration.7. Skin InfectionsSkin is predisposed to fungal infections (such as athlete's foot or ringworm) and bacterial infections (such as impetigo) in monsoons due to high humidity and persistent dampness. Wet clothing or the use of dirty towels can make things worse.Shower every day, wear loose cotton clothes, and dry the skin well, particularly in creases and folds.8. LeptospirosisSpread by contact with contaminated water through urine of animals, leptospirosis is contracted after wading through floodwater. It results in symptoms such as fever, muscle pains, and vomiting. Severe infection may cause kidney injury or meningitis.Do not walk in standing water or puddles when it rains. Wearing waterproof shoes is advisable. Consult a doctor at the earliest sign of symptoms.9. AmoebiasisInduced by the Entamoeba histolytica parasite, amoebiasis is transmitted via contaminated food or water. It causes abdominal pain, loose stools, and tiredness. Although most of the time self-limiting, chronic infections can cause damage to the intestines.Always eat food from clean sources, and wash vegetables thoroughly.10. Snake BitesAlthough not waterborne, snake bites increase during the monsoon as snakes are washed out of their burrows into human settlements. The danger is particularly risked in rural and farm areas.Avoid going barefoot through dense undergrowth or flooded fields. Wear long pants and boots.How To Prevention Getting Sick in Monsoon?Drink Boiled or Purified Water: This is the best method of destroying waterborne pathogens. Install reliable water purification systems and never drink unverified water.Practice Strict Hand Hygiene: Wash hands always after using the bathroom and before eating or cooking. Handwashing with soap can cut diarrheal disease risk by as much as 48%, says The Lancet.Keep Surroundings Clean: Drain standing water to avoid breeding mosquitoes (responsible for dengue and malaria), and wash your water storage vessels regularly.Consume Fresh and Well-Cooked Food: Wash fruits and vegetables thoroughly, use cooked meats, and avoid eating street food during rainy days.Maintain Adequate Sanitation: Use well-built toilets and refrain from open defecation to minimize source water contamination.Vaccinate Children: Make routine vaccinations current, particularly for hepatitis A, typhoid, and flu, which provide immunity against monsoon-borne illnesses.While monsoons have the charm of rainy afternoons and emerald greenery surrounding them, they also bring with them grave health issues if measures aren't adopted. The aforementioned waterborne illnesses not only affect individual health but also weigh heavily on public health services worldwide.
