Thailand has registered 745 new coronavirus cases, with a new death reported in Bangkok, where a semi-lockdown went into effect.

The Centre of Covid-19 Situation Administration said that the new infections bring the total number since last January to 8,439, while the death toll has climbed to 65, according to a report by AP.

Nearly all the infected workers were employed in fish markets and factories and are all housed in dormitories that have been closed off to the public since the recent outbreak began. Since the initial spike in late December, the virus has now been found in 54 of Thailand’s 73 provinces.
