Rainy, cool weather may have prolonged peak flu season
The rainy weather may have caused the peak flu season to last a little longer than usual, say doctors.
The season usually runs from September to December, but patients are still turning up at clinics.
Dr Lim Chien Wei, cluster head of Healthway Medical Group, said the rainy and cool weather could have allowed viruses to survive longer.
Polyclinics saw an average of 3,158 patients with acute respiratory infections every day during the first week of this month, said the Health Ministry.
This was up from the 2,836 patients who were seen in the same period last year. The figure had not crossed the 3,000 mark since October last year.
Dr Michael Wong, a family physician at Raffles Medical, said he has seen an increase in the number of patients with symptoms such as cough and nasal congestion in recent weeks. He added that while a person cannot literally "catch a chill", the chill could be a factor in allowing viruses to spread.
"Staying indoors increases the proximity between people," Dr Wong said. "With the increased recycling of air indoors or in an air-conditioned environment, respiratory viruses have a higher incidence of spreading."
Dr Lim noted: "When adults and children start going back to work and school after the holidays, the spread of viruses can become more prevalent."
Singapore has two peak flu seasons a year, one from April to June, and the one winding down now.
Dr Lim said he sees about 20 per cent to 30 per cent more patients with a cold or flu during these periods.
While influenza and the common cold are caused by viruses, flu symptoms can be more severe and result in serious health problems such as pneumonia.
"Antibiotics are of no use against cold viruses and are often not prescribed unless there is also a bacterial infection," said Dr Wong.
Instead, treatment is typically aimed at helping to alleviate the symptoms. Those infected should drink plenty of fluids and practise proper hygiene to avoid spreading the illness to others.
