PETALING JAYA: Covid-19 self-test kits, which will soon hit the shelves after being allowed to be imported and sold in Malaysia, could become a game changer to help Malaysians live with the virus, say health experts. With these self-test devices, experts said active case detection could easily be done from the comfort of one’s own home. The kits can also be deployed for weekly workplace screening so that people may return to work and get the economy up and running.
