Why Some Malaria Cases Take Longer to Diagnose in Bangkok

Bangkok, ThailandSun Aug 23 2026

A recent study in Bangkok revealed that more than half of people with P. vivax malaria didn't get diagnosed quickly enough. Researchers looked back at 384 cases from 2010 to 2024 at a special hospital for tropical diseases. They found 58.3% of patients waited more than four days from when symptoms started before getting the right diagnosis. This delay matters because early treatment can prevent serious problems.

The main reason people waited so long was that they didn't go to a doctor soon enough. Nearly 74% waited over three days before seeking care. Even when they did see a doctor, mistakes happened - 25.5% were given the wrong diagnosis initially. Only about 14% had delays in getting the correct medical test results. This shows the problem starts before patients even reach the hospital.

Certain groups faced higher risks. People aged 45-54 were nearly three times more likely to have delayed diagnosis. Office workers and business people had almost five times the risk compared to others. Those who had never had malaria before were more than twice as likely to be misdiagnosed. Getting the wrong diagnosis at the first visit made delays even more likely.

The findings suggest that in cities where malaria is rare, doctors might miss the signs. The study recommends that any person with fever should be tested for malaria if they've traveled to areas where the disease exists. This could help catch cases earlier and prevent complications.
