Mysuru: The city is witnessing a noticeable surge in cases of viral gastroenteritis over the past few weeks, with health experts attributing the spike to intense summer heat and rising temperatures across the region.

According to A K Satheesh Rao, senior consultant in medical gastroenterology and hepatology, the early onset and severity of summer this year have significantly impacted digestive health among residents.

15–20 per cent rise in cases reported

Doctors in Mysuru have observed a 15–20 per cent increase in patients presenting with gastrointestinal issues. Common symptoms include frequent vomiting, abdominal discomfort, diarrhoea, and rapid dehydration.

“Prolonged spells of heat and high temperatures are taking a toll on people’s digestive systems. We are also seeing a worrying rise in dehydration cases,” Dr Rao said.

While seasonal increases in such illnesses are not unusual during summer, medical professionals note that the intensity and frequency of cases this year are higher than expected.

Viral gastroenteritis on the rise

A majority of the recent cases have been diagnosed as Viral gastroenteritis, a contagious intestinal infection that spreads primarily through contaminated food and water.

Doctors warn that the infection can spread quickly, especially in conditions where hygiene practices are compromised or safe drinking water is not ensured. Children and elderly individuals are particularly vulnerable to complications arising from dehydration.

Health experts stress that timely medical attention is crucial in severe cases to prevent complications such as electrolyte imbalance and extreme dehydration.

Heat and hygiene key factors

The current spike has been linked to multiple factors, including extreme heat, improper food storage, and consumption of contaminated water. With temperatures soaring earlier than usual this year, perishable food items are more likely to spoil quickly, increasing the risk of infection.

Additionally, inadequate hydration during hot weather can weaken the body’s resistance, making individuals more susceptible to infections.

Preventive measures advised

Doctors have emphasised simple yet effective preventive measures to reduce the risk of infection. These include:

  • Drinking clean, filtered, or boiled and cooled water
  • Avoiding street food and consuming freshly prepared home-cooked meals
  • Maintaining proper hand hygiene, especially before eating
  • Storing water and food safely to prevent contamination
  • Staying adequately hydrated throughout the day

“Basic precautions like safe water consumption and hygiene can go a long way in preventing such infections,” Dr Rao noted.

Conclusion

With Mysuru experiencing an early and intense summer, health experts are urging residents to remain cautious and adopt preventive practices to avoid gastrointestinal illnesses. While the current surge in viral gastroenteritis is manageable, increased awareness and timely intervention will be key to preventing further spread and complications.
