The Department of Disease Control (DDC) expects the Covid-19 caseload to rise after the Songkran Festival because of people's activities during the festival and their travel.
The DDC said the number of cases after Songkran may be higher than after the New Year when measures against Covid-19 were relaxed.
It said between April 9-15, 435 new infections were admitted into hospitals for treatment, an average of 62 per day or 2.5 times higher than the previous week.
During the period, there were two fatalities.
The DDC said most of those admitted for treatment in hospitals during this time are not in a serious condition because they had previously been vaccinated or had the disease.
After Songkran, people are advised to keep themselves under observation for at least seven days and avoid close contact with the elderly or people with chronic diseases.
