The new Omicron subvariant CH.1.1, which has been detected in 67 countries including Thailand, can evade immunity produced by some vaccines but its rate of transmission is low, the Department of Medical Sciences said.

The department has only diagnosed around 300 patients so far, as the majority of cases at the moment, about 80%, are caused by the BN.1 subvariant of the novel coronavirus.

People travelling to China, India, Nepal and Myanmar must take an RT-PCR test before arrival. Based on 2,022 cases recorded between Jan 8 and Feb 3, the department found a decline in positive test results from 10% to 1% among Thai people, with a corresponding drop among Chinese tourists from 7% to 2%.

In the week from Jan 28 to Feb 3, 94 people — 87 Thais and seven foreigners — tested positive for Covid-19 during initial examinations.

The BA.2.75 subvariant was detected in 82 cases, followed by BA.4/BA.5 in 8 cases and others in the remaining four cases.

Meanwhile, a source from the Department of Disease Control said that the cabinet will receive 1.5 million doses of vaccines donated by South Korea and France, which are expected to arrive shortly.

The department will set up a committee to clarify which groups should receive the newer jab.
