The highly transmissible BA.4 and BA.5 sub-variants of Omicron are keeping people alert to a possible outbreak, but Covid-19 may not be the most serious concern as the economy ambles forward.
The new viral strains come as most people are vaccinated, with 76.4% of the 70 million inhabitants of Thailand inoculated with two doses of vaccine and 42.6% receiving more than two shots as of June 30, according to the Public Health Ministry.
