Coronavirus: Testing sewage an 'easy win' - BBC News

Coronavirus: Testing sewage an 'easy win' - BBC News



Sewage-based surveillance suggestion

Testing wastewater samples for the coronavirus could help local authorities to identify and tackle COVID-19 outbreaks sooner, scientists say. Studies in the United Kingdom suggest that this approach could help to detect infection spikes up to ten days earlier than existing medical-based tests. “By sampling wastewater at different parts of the sewerage network, we can gradually narrow an outbreak down to smaller geographical areas, enabling public-health officials to quickly target interventions,” says pollution scientist Andrew Singer. “It seems obvious that we should be doing this.”

One U.K. trial is transforming COVID-19 treatment. Why haven’t others delivered more results?

https://www.sciencemag.org/news/2020/07/one-uk-trial-transforming-covid-19-treatment-why-haven-t-others-delivered-more-results?utm_source=Nature+Briefing&utm_campaign=e9079e5ba2-briefing-dy-20200703&utm_medium=email&utm_term=0_c9dfd39373-e9079e5ba2-44992633

The trial transforming COVID-19 treatment

The United Kingdom’s large-scale trial Recovery (Randomised Evaluation of COVID-19 Therapy) stands out among the dozens of ongoing clinical studies that aim to test potential treatments for coronavirus infection. Involving more than 12,000 participants from hundreds of hospitals, the effort has delivered widely accepted verdicts on the potential of several antiviral drugs, and provided insights that have changed how physicians around the world consider treating COVID-19. Meanwhile, other large-scale initiatives have struggled to recruit participants and been slow to deliver results.

A guide to R — the pandemic’s misunderstood metric

A guide to R — the pandemic’s misunderstood metric



A guide to R — the misunderstood metric

Researchers are worried that politicians might be focusing too much on a single metric when assessing the severity of coronavirus outbreaks. The reproduction number — known as R — is the average number of people each person with a disease goes on to infect. But it is an imprecise estimate that relies on assumptions, and too much attention to it could obscure the importance of other measures, such as trends in numbers of new infections, deaths and hospital admissions. “Epidemiologists are quite keen on downplaying R, but the politicians seem to have embraced it with enthusiasm,” says infectious-disease expert Mark Woolhouse. “We’re concerned that we’ve created a monster.”

United States buys nearly all the remdesivir

The US Health Department has announced that it is buying almost all of the next three months’ production of the antiviral drug remdesivir from US company Gilead. Clinical trials suggest that the drug can speed up recovery from coronavirus infection in people with severe COVID-19, although it is still unknown whether the treatment can increase survival rates. Critics say the move undermines international efforts to fight the pandemic. "It so clearly signals an unwillingness to co-operate with other countries and the chilling effect this has on international agreements about intellectual-property rights,” says science-policy researcher Ohid Yaqub.

The Pandemic

Ahmedabad-based pharma firm Zydus Cadila expects to complete the first two phases of human clinical trials for its Covid-19 vaccine candidate, ‘ZyCov-D’, in the next three months, according to its chairman. The trials will begin this month in over 1,000 patients across multiple sites.

The JEE (Main) and the National Eligibility cum Entrance Test (NEET) have been delayed further by a month due to the unabated rise in coronavirus cases. The JEE Main will now be held over six days between September 1 and September 6. NEET, meant for undergraduate medical programmes, will be held on September 13. JEE (Advanced) will be held on September 27. 

In order to ease the pressure on hospitals amid a Covid spike, the Karnataka government on Friday approved introduction of home isolation, provided the houses of asymptomatic patients have a room for isolation with an attached bathroom. “Only those who are asymptomatic or mildly symptomatic shall be allowed to be in isolation at home,” according to the SOPs released by the health department.
