With the onset of the monsoon, the risk of several water-borne, mosquito-borne, and bacterial infections increases significantly due to stagnant water, flooding, poor sanitation, and contaminated food and water. Many of these diseases can start with mild symptoms similar to the flu, but if they're diagnosed early, you can get the appropriate medical care in time, avoiding serious complications. Early Symptoms Of Various Monsoon Diseases One of the important ways to prevent monsoon infections and diseases is to identify warning signs early, Dr. Amit Saraf, Director, Department of Internal Medicine, Jupiter Hospital, told HealthandMe. Leptospirosis Leptospirosis gained attention after its cases surged in Kerala recently. The infection has also been reported in Maharashtra, Gujarat, Tamil Nadu, and Karnataka. The bacterial infection typically spreads via contact with water or soil that has been contaminated by the urine of animals infected with leptospirosis, especially during floods. Initial signs and symptoms include: High fever Chills Intense muscle pain (especially in calves) Headache Red eyes Nausea Vomiting“Wearing protective footwear, avoiding wading in floodwaters, and covering any open wounds will help minimize the risk of infection,” Dr Saraf recommended. Typhoid Typhoid, a bacterial illness, is transmitted via contaminated food and water. Early symptoms include:High fever Headache Weakness Loss of appetite, Abdominal pain Constipation or diarrhea Body aches Dr. Saraf said: “It can cause serious gastrointestinal issues if not treated. Safe drinking water, good hand hygiene, and freshly cooked food are important preventive measures.” Cholera Cholera is a water-borne bacterial disease that commonly occurs during monsoons. It often begins with excessive watery stools, vomiting, leg cramps, and rapid dehydration. Dehydration can quickly become an immediate danger of cholera. The doctor said: “Prevention includes drinking clean water, eating hygienically prepared food, and practicing proper sanitation and handwashing.” Dengue Dengue is one of the most common viral diseases spread by Aedes mosquitoes. Often reported in various Indian states during the monsoon, dengue presents with flu-like symptoms. Dengue usually begins with high fever, severe headache, pain behind the eyes, extreme muscle and joint pain, nausea, skin rash, and fatigue. Malaria Malaria, a common monsoon disease, is spread by infected mosquitoes and characterized by the following symptoms:Recurrent fever Shivering or sweats Headache Muscle pain Weakness Nausea Vomiting Dr Saraf said, “Early diagnosis is important to prevent severe diseases. The best ways of preventing mosquito bites are by using mosquito repellents, mosquito nets, and the elimination of breeding sites.” ChikungunyaMosquito-borne viral diseases are reported to be the highest during the rainy season. One of them is Chikungunya. The infection is usually marked by sudden high fever and severe joint pain in the limbs. Other early symptoms may include headache, muscle pain, fatigue, and skin rash. “The infection is usually not deadly but can cause joint pain for weeks or months. Preventive measures include mosquito control and avoidance of mosquito bites,” the expert advises.Gastrointestinal InfectionsDuring the monsoon period, gastrointestinal infections are also more common as food and water sources are more likely to get contaminated. Early signs of gut infections may include diarrhea, vomiting, cramps, nausea, bloating, fever, and dehydration. The majority are due to bacteria, viruses, or parasites. The expert said that the risks can be minimized by maintaining food hygiene, drinking boiled or purified water, washing fruit and vegetables before cooking and consuming, and refraining from eating street foods and drinks.
