Ahmedabad: With the monsoon finally arriving in the city, many Amdavadis have begun experiencing the effects of the seasonal transition, with city-based physicians reporting a rise in patients suffering from fever, cough and viral infections in their OPDs.One of the most common complaints doctors are encountering is prolonged fatigue and weakness even after the fever subsides. Experts said the period is marked by fluctuating temperatures and the proliferation of viruses and bacteria, making people with weaker immunity particularly vulnerable.Dr Pragnesh Vachharajani, a city-based physician, said that after an intense summer during which temperatures remained above 40 degrees celsius, a significant drop was recorded last week. “The transition period is marked by hotter days and cooler nights. This time, night temperatures did not fall much earlier, but last week saw a decline in both maximum and minimum temperatures. Many patients fell ill as their bodies struggled to cope with the fluctuation,” he said.Physicians said the most common pattern involves three days of high-grade fever accompanied by headache and body ache, followed by persistent fatigue.“For the past 10 days or so, cases of viral infections have increased, often presenting with fever, dry cough and general discomfort,” said Dr Pravin Garg, a city-based physician. “We advise patients to take plenty of fluids and adequate rest. Most cases are not serious and usually resolve with rest at home and appropriate medication.” He advised patients against self-medication.“One should also avoid outside food and use room-temperature water whenever possible. Air-conditioners can affect people in two ways. First, they contribute to fluctuations in body temperature, and second, they often keep the virus circulating within the same environment. As a result, if one person is infected, the chances of others contracting the infection become higher,” added Dr Vachharajani.
