Coronavirus Morning Recap – Nov 18: Certain levels of humidity in the home could protect you from Covid, Pfizer’s vaccine produces a strong response against BQ.1

Good morning. This is Jonathan Spira’s report. Here now the pandemic news from around the world on the 953 day of the pandemic.

Just one day after cleaning and turning on my home humidifiers, I read a study by MIT researchers suggesting that indoor relative humidity may have an effect on SARS-CoV-2 transmission.

The research, led by CA Verheyen at the Institute of Medical Engineering and Sciences and published earlier this week in the Journal of the Royal Society Interface, showed that when the indoor relative humidity of countries in the northern and southern hemispheres falls by below 40% in its coldest months, Covid cases and deaths are also up in these regions. It also found that, in more tropical regions, when indoor relative humidity exceeded 60%, there was also an increase in infections and deaths.

A “sweet spot” of 40% to 60% relative humidity, as the two researchers called it, is a bit outside of what most people find comfortable, which is a range of 30% to 50% relative humidity. .

Still, I was pleased to note that when I woke up, the relative humidity levels at home were at 40%.

In other news we cover today, Los Angeles is telling people to wear a mask, Pfizer-BioNTech’s new Covid booster produces a strong immune response against the emerging variant BQ.1, and Australians are seeing a dramatic increase in infections. new covid infections.


Pfizer-BioNTech said its new bivalent vaccine targeting the omicron BA.4 and BA.5 sublineages produced higher virus-neutralizing antibodies in older adults against the emerging BQ.1.1 subvariant than the partners’ original vaccine.

As Covid cases and hospitalizations across the country continue to rise, the Los Angeles County Health Department said the use of masks in indoor public spaces is once again “strongly recommended.”

In Texas, Governor Greg Abbott has banned immunization mandates in state public schools.


In Australia, health officials say “here we go again” after seeing an 80% increase in covid cases in some states over the previous week. They have urged the public to wear face masks indoors and on public transportation.

Health authorities in Manitoba, Canada’s fifth most populous province, said the threat level from Covid was “serious” for the third week in a row. The rating is based on the combined estimates and analysis of hospitalization and wastewater that form the Hazard Index in Canada.

Meanwhile, the Toronto Transit Commission said it would rehire some of the 367 workers it laid off for failing to comply with vaccine mandates earlier in the pandemic as it prepares to lift that policy on November 27. However, the agency said it will also change its employment contracts in an attempt to prevent conflicts from arising again, should the need for a vaccination mandate or other public health requirement for workers arise.

Chaoyang, Beijing’s largest district, urged residents to stay home over the weekend as Covid outbreaks in many Chinese people grew.


The European Center for Disease Prevention and Control said infections by some antibiotic-resistant pathogens known as superbugs have more than doubled in healthcare settings in Europe since the start of the pandemic. The news shows the broader impact of the pandemic on healthcare beyond SARS-CoV-2 cases.
