The World Well being Group (WHO) rapidly responded to a group of researchers’ essay revealed early this week (7/6/20) urging public well being authorities to acknowledge that SARS-CoV-2 can unfold by the use of small droplets that float within the air (“aerosol transmission” or “airborne transmission”), reports Dyani Lewis for Nature (7/8/20). The WHO stated on 7/7/20 that “it’s going to subject new pointers about transmission in settings with shut contact and poor air flow,” Lewis’s story states. After which on 7/9/20, the company acknowledged in an online post that aerosol or airborne transmission takes place not solely in hospital settings but additionally in different indoor settings, a number of media retailers reported [it seems like Apoorva Mandavilli at The New York Instances broke the news; right here is also coverage by Hilary Brueck at Enterprise Insider]. The influential company’s transfer holds implications for security suggestions worldwide associated to the brand new coronavirus, together with considerations about: the effectiveness of indoor-air air flow, filtration, and disinfection; whether or not material face-masks must be worn by the general public, significantly indoors; and whether or not well being care staff treating COVID-19 sufferers ought to put on tight-fitting N95 respirator masks, not simply looser-fitting surgical masks. Lewis’s story options some intriguing nuggets, together with the main points of disputes about aerosols proof and descriptions of case research that present “circumstantial proof” of aerosol transmission for SARS-CoV-2.

At Science journal, Jennifer Couzin-Frankel, Gretchen Vogel, and Meagan Weiland summarize limited findings and patterns seen to date within the effectiveness of methods for limiting the unfold of SARS-CoV-2 in re-opened colleges (7/7/20). What works to maintain each schoolchildren and the bigger group secure? “A mixture of preserving scholar teams small and requiring masks and a few social distancing,” the story states. On prime of that, kids hardly ever unfold the virus, analysis reveals, though some preliminary findings recommend that older kids contaminated with the virus are extra contagious than are youthful ones, based on the story. The story inventories the virus-safety insurance policies of many faculties and nations worldwide on subjects equivalent to permitting kids to play collectively, mask-wearing, and methods to reply when kids take a look at optimistic for the virus. Knowledge from European nations recommend that re-opened colleges should not inflicting vital will increase in SARS-CoV-2 circumstances within the wider communities, the story states, however “it’s arduous to make certain,” as a result of colleges re-reopened similtaneously different public sectors.

Marlene Cimons on the Washington Put up (7/3/20) requested 5 public well being and infectious illnesses researchers, together with Dr. Anthony Fauci, director of the U.S. Nationwide Allergy and Infectious Ailments Institute, about their private practices to cut back their threat of SARS-CoV-2 an infection. Their replies in her story here are very helpful. Subjects lined embody mask-wearing in public; whether or not they let others inside the house or socialize with others; visits to barbers or hair salons (nope); buying habits (all of them go to the grocery retailer however put on masks and keep distant from others); mail-opening habits; indoor restaurant eating; journey by air, bus or subway (most of them wouldn’t achieve this or haven’t achieved so, or solely would for an emergency); gymnasium visiting (near universally, they might not or don’t, apart from a pair saying outside swimming could be OK); routine physician and dentist visits; and whether or not they would let kids return to high school.

Physicians with Texas Medical Affiliation’s COVID-19 Job Drive and the affiliation’s Committee on Infectious Ailments tweeted a graph on 7/3/20 that ranks their estimates of the an infection threat ranges related to varied actions. Lowest: opening mail, restaurant takeout, pumping gasoline, enjoying tennis, going tenting. Highest: consuming at a buffet, understanding at a gymnasium, going to an amusement park, going to a movie show, attending a big music live performance, going to a sports activities stadium, attending a spiritual service with > 500 individuals current, and going to a bar.

The headline of this mythbusting 7/1/20 Wired story by Gilad Edelman cuts to the chase: “‘Covid events’ should not a factor.” Studying this story made me happier.

Jonathan Lambert at Science Information has written a crisp overview of the primary six months of the COVID-19 pandemic within the U.S. A graph close to the highest of the story clearly reveals how poorly the U.S. is faring in reported case counts in contrast with different areas and nations previously month. “We’re beginning to see the epidemiological impression of releasing social distancing measures with out essentially having different management measures in place across the nation,” says a Johns Hopkins Heart for Well being Safety skilled quoted within the story. These measures embody a adequate variety of contact tracers (staff paid to trace down those that have interacted with individuals who lately take a look at optimistic for the virus). The U.S. presently employs a couple of third of the quantity that some consultants estimate are wanted to successfully management the unfold of the virus, the story suggests. The story notes the difficulties posed by the nation’s decentralized, underfunded public well being system, but additionally supplies hope by describing profitable contact tracing efforts in a county in Maryland (7/1/20).
