The Thai government on Thursday announces new compulsory quarantine measure for arrivals from four countries and two territories in a bid to contain the spread of the coronavirus. The move came as the Thai postal service began disinfecting all packages received from overseas, although the World Health Organization has said it is safe to receive post from badly affected countries such as China. The quarantine announcement, published in the official Royal Gazette on Thursday, classified South Korea, China, Macao, Hong Kong, Italy and Iran as “dangerous communicable disease areas”.
