San Lazaro Hospital Medical Director Dr. Rontgene Solante on Wednesday, Aug. 14 called for immediate medical intervention for individuals who waded in floodwaters, as the facility reported an increase in moderate to severe leptospirosis cases following the widespread flooding last month.

In a televised briefing, Solante said the hospital had admitted 149 leptospirosis cases in the past week and a half, a significant increase from the two or three cases per month seen in previous months.

Most patients were exposed to floodwaters during the July 24 flooding, with symptoms typically appearing about two weeks later, he added.

He said the patients’ ages range from 19 to 69, showing that the disease affects people of all ages. 

Solante also pointed out that more than 60 percent of the cases are moderate to severe, with severe cases being more common.

He added that eight patients, aged 28 to 45, have died, mainly due to complications such as renal failure and pulmonary hemorrhage.

Solante said the increase in leptospirosis cases is not only due to people wading through floodwaters but also because many swam in them. 

He explained that the leptospirosis bacteria entered the body through the mouth, nose, or eyes of those who swam in floodwaters, which increased their risk of developing moderate to severe leptospirosis.

“All of them initially show fever, which is followed by body aches, headaches, and calf pain within two to three days. Some patients also experience reddening of the eyes. However, many patients notice a decrease in urine output as symptoms persist, often only seeking hospital care when they can no longer urinate. By then, they are frequently jaundiced and may have difficulty breathing upon arrival at the hospital,” the infectious disease expert said in Filipino.

Solante reiterated that leptospirosis is treatable with antibiotics.

However, he observed that none of the patients at San Lazaro Hospital had received prophylaxis.

“Preventive measures include avoiding wading in floodwaters if possible. If you must wade through floodwaters, wearing protective gear such as boots is essential. If exposure cannot be avoided, seek prompt care at a health center, where leptospirosis prophylaxis is available and can be very effective and life-saving,” he said.

Solante added that the hospital has addressed the recent surge in leptospirosis cases by opening a new ward dedicated exclusively to these patients, separate from those with other infectious diseases. 

He also said that they are still able to accommodate leptospirosis patients.
