China still needs to pay close attention to the contagion for the next one to two months and avoid large-scale gatherings, and measures such as those requiring a 14-day quarantine of people returning to big cities should continue. δ????????£??????????????鱣??????裬???????????????????£???????????????????14??????????????????? "If we well implement such preventive measures, and the number of new infection cases remains zero for a certain period of time, in one or two months it'll be time to take off masks," Zhang said. Last month, companies in Guangdong province, Beijing and Shanghai reported producing a new type of face mask that uses a nanomaterial membrane, rather than the typical melt-blown fabric, to filter bacteria, viruses and other pathogens, according to local health and medical products authorities. ?????????????????????????????????????????????2???????????????????????????????????????????????????????????????????????????????????????????????????????? The new masks are on par with N95 standards, meaning they filter particles of all sizes with at least 95 percent efficiency. The masks are also comfortable, easy to breathe through and can be reused up to 20 times depending on the user's setting and wear time, the authorities said. The retail price for the masks created by companies from Shanghai will be around 15 to 20 yuan each. ?????????????????????????84???????????????????20?κ??????????filtering efficiency???????????????????????????????б???????????????????10?Ρ? ?????????????????????????£???????????????????????????disinfect their masks???????????????????????????70?????????????15?????soak the used masks in higher-than-70-degree water for 15 minutes??????56?????????????30???????????????????????????????????????????????????紵?????罫??????ɡ?
