According to Jurai Wongsawat, spokesperson for the Department of Disease Control, 49,065 cases were recorded between May 11 and 17, with another 12,524 new cases reported since May 18, The Nation reported.
The XEC subvariant, a recent offshoot of Omicron, is believed to be the primary cause of the spike, spreading seven times faster than seasonal influenza, according to Thailand’s Ministry of Public Health, the Bangkok Post reported.
However, fatality rates remain low, around 0.02%, thanks to widespread vaccination and access to antiviral treatments, Jurai noted.
Despite the mild severity for most patients, officials are urging the public to help protect vulnerable groups, including the elderly, those with chronic illnesses, pregnant women, and young children.
"People with respiratory symptoms should stay home, self-test, and seek medical care if they test positive," Jurai advised.
The current wave is expected to continue for another two to three months, but infection rates could decline sooner if people maintain strict personal hygiene and preventive behaviors.
While Thailand is rolling out free flu vaccinations for vulnerable populations between May and August, Covid-19 boosters will not be provided free of charge. High-risk individuals are encouraged to consult medical professionals regarding booster eligibility.
Bangkok currently leads the country in both Covid-19 and flu infections.
