Low-wage dormitory-dwelling migrant workers in Singapore were disproportionately affected by coronavirus disease 2019 (COVID-19) infection. This was attributed to communal living in high-density and unhygienic dormitory settings and a lack of inclusive protection systems. However, little is known about the roles of social and geospatial networks in COVID-19 transmission. The study examined the networks of non-work-related activities among migrant workers to inform the development of lockdown exit strategies and future pandemic preparedness. ⋯ Social and geospatial networks of migrant workers should be considered in the implementation of lockdown exit strategies while addressing the improvement of living conditions and monitoring systems. Essential services, like remittance and grocery shopping at affordable prices, need to be provided near to dormitories to minimize excess gatherings.

A coronavirus disease (COVID-19) genome surveillance has been conducted at four international airports in Japan, revealing a potential imported COVID-19 risk from multiple countries. The quarantine surveillance based on genome sequencing can enhance sequencing efforts worldwide, as returning travelers may serve as excellent sentinels for the global pandemic.

Metropolitan wholesale markets are at high risk of coronavirus disease 2019 (COVID-19) spread as originally seen in Wuhan, China. We studied the metropolitan wholesale market-related resurgence of COVID-19 in Beijing, China, and highlight the importance of control strategies based on the temporospatial characteristics of wholesale markets.

Nearly a year into the COVID-19 pandemic, we still lack effective anti-SARS-CoV-2 drugs with substantial impact on mortality rates except for dexamethasone. As the search for effective antiviral agents continues, we aimed to review data on the potential of repurposing antiparasitic drugs against viruses in general, with an emphasis on coronaviruses. ⋯ As the search for an effective drug active against SARS-CoV-2 continues, we argue that pre-clinical research of possible antiviral effects of compounds that could have antiviral activity should be conducted. Clinical studies should be conducted when sufficient in vitro evidence exists, and drugs should be introduced into widespread clinical use only after being rigorously tested in RCTs. Such a search may prove beneficial in this pandemic or in outbreaks yet to come.
