Secretary for Health Lo Chung-mau said the supply of paracetamol is stable but "[the possibility of] regulating the trading of these medicines will not be ruled out." He said the SAR has enough paracetamol for six months and will reserve them for the underprivileged. On Covid testing, Lo said people can pay for PCR tests at 85 community centers or take them at private hospitals and laboratories, with prices capped at HK$150. Meanwhile, deputy chief secretary for administration Warner Cheuk Wing-hing said the government will monitor parallel trading activities after the border reopens. The Immigration Department will set up a list of "suspected parallel importers" and may ban visitors with suspected purposes.
