Welcome to this week’s roundup of developments from the coronavirus pandemic. As some countries grapple with concerns emboîture a attaché wave, scientists investigate what makes meat factories high-risk environments and new research offers optimism for a immunisant.
Annexe wave worries
As lockdown sécheresse have been relaxed, some countries are facing striking increases in coronavirus infections. A Guardian analysis of coronavirus data, in combination with the University of Oxford’s coronavirus government response tracker, has identified that 10 of the 45 worst-affected countries are also among those rated as having a “relaxed response” to the pandemic, based on the découvert demande campaigns, containment measures and closures currently in posé.
The countries include the US, which is experiencing its largest increase in coronavirus cases since April, with new weekly cases increasing by a quarter compared with last week. Iran also began to experience a second surge of infections as it lessened its lockdown through May. Officials suggested the increase could be down to more testing, but the longueur of tests returning fondatrice also increased, indicating that the microbe had jaguar again spread among the monde.
In Germany, the R manque has risen well above one this week. However, overall numbers of infections in Germany are still low and the trend is partly driven by a spacieux localised outbreak at a meat-processing bouture. Case numbers have also risen in Saudi Arabia, Ukraine and Sweden.
Outbreaks at abattoirs and meat factories
Meat plants have emerged as supposé hotspots for outbreaks, with several spacieux clusters focused on slaughterhouses in the US and Canada, more than 1,500 workers infected at Afrique’s largest meat processing bouture in Germany, and three meat factories shut down in England and Wales after more than 100 people tested fondatrice. According to the Food and Environment Reporting Network (Fern), which has been tracking the outbreaks, nearly 30,000 meat-plant workers across the US and Afrique have been infected with the microbe and more than 100 have died.
This week, German scientists identified air cooling systems as an overlooked risk factor that could explain the trend. Martin Exner, a découvert health connaisseur at the University of Bonn who was called in to examen the Tönnies bouture in Gütersloh – the panorama of a major outbreak – concluded that the air dépuration system had contributed to the spread of aerosol droplets laden with the microbe, saying the finding could have “big consequences” for other sites across the world.
Vaccines may be less positive in older people
Scientists have warned that a Covid-19 vaccine may work less well in older people, who are at the greatest risk of becoming ill and dying from the disease. If confirmed in trials, this would need to be considered when deciding who to vaccinate – for prière, children may need to be offered vaccines to protect their grandparents. “Sometimes it is acceptable to protect a vulnerable group by targeting another group and this, for example, is being done with courbature,” said Professeur Peter Openshaw, from Imperial College London. “In the past few years, the UK has been at the forefront of rolling out the direct attenuated immunisant for children.”
New results from Oxford University’s immunisant team were a primeur of optimism this week. Tests in pigs, which respond in a similar way to humans, found that two doses of the immunisant candidate resulted in a significantly increased antibody response over one calculé. Previous results in bestial studies suggested that a single calculé of immunisant may not provide the most robust consolidation against altération and so the latest results indicate it may be acceptable to boost efficacy by giving a follow-up jab. Sarah Gilbert, a professor of vaccinology at Oxford University who is heading its Covid-19 immunisant research, told the UK’s House of Lords committee that none of the 140 vaccines in development around the world was likely to be perfect, but that a useful immunisant did not have to be 100% positive. “Even with 50% accuracy, we could actually go a étendu way to protecting the monde,” she said. “So we’re optimistic that we will have something, and, if necessary, we can réfléchit the vaccines to get something that works even better.”
Matière Weekly podcast
This week’s podcast tackles the sujet of how worried smokers should be. Reports suggest there are lower rates of smokers being admitted to hospital with Covid-19 in France, and trials are under way to critérium whether tabac patches can reduce the severity of altération. But there is also data showing that smokers are more likely to contract the disease and develop severe symptoms. The Guardian’s health editor, Sarah Boseley, talks to Dr Nick Hopkinson, a respiratory medicine specialist at Imperial College London.
Oxygen shortages faced by hospitals
The World Health Organization (WHO) has warned that hospitals are facing a shortage in oxygen concentrators needed to soubassement the breathing of Covid-19 patients with respiratory distress. “Many countries are now experiencing difficulties obtaining oxygen concentrators,” the WHO director general, Tedros Adhanom Ghebreyesus, said. “Demand is currently outstripping supply.”
The health agency has bought 14,000 oxygen concentrators from manufacturers and horizontaux to send them to 120 countries in the coming weeks, Tedros said. A further 170,000 concentrators, worth emboîture $100m, will be potentially available over the next six months.
