B.1.617.2: an update

PHE released the latest epidemiological summary of the B.1.617.2 VOC (aka “the variant that was first identified in India”) a few days ago. Evidence is emerging rapidly, and the datasets are far from conclusive. But it now seems clear that B.1.617.2 is more transmissible, causes no more hospitalisation or mortality, and vaccine effectiveness is slightly reduced when compared with other variants.

The role of ventilation in preventing the transmission of SARS-CoV-2

I gave a talk at the Sussex Infection Prevention Development Week yesterday on ventilation and preventing the spread of SARS-CoV-2. I learnt a lot in putting together the talk, so thought I’d share my slides (here) and some of the key points. Ventilation is a crucial way to prevent the spread of SARS-CoV-2 (and other respiratory viruses), and I hope that improved ventilation in health and social care settings will be one of the good things to come out of this pandemic.

The role of IPC, vaccination, and OTC distribution in AMR

I had the privilege of chairing a session in the BSAC Spring Conference webinars yesterday about the role of IPC, vaccination, and OTC distribution in AMR. The session had a talk from Professor Andreas Voss on IPC as a cornerstone of successful stewardship, Dr Elizabeth Klemm on prevention through vaccination, and Dr Abdul Ghafur on community pharmacy and the challenge of over-the-counter (OTC) distribution.

A plea to stay away from work if you’re ill

I have a confession. A few years ago I came to work when I was ill. Not desperately ill – but clammy-stay-in-bed-didn’t-want-to-ride-my-bike ill. Ill enough to stay away from work. But I was really busy and had loads to do. Working from home wasn’t really an option back then – you know, in the days when meetings were mainly face-to-face. Sure, you could dial in. But people often forgot you were there and couldn’t really hear you properly when you said something. So, I came to work. It was just before Christmas. And my gift to my office-sharer was a really nasty respiratory virus for Christmas.

Early data on COVID-19 vaccine effectiveness in England

Results from the SIREN study published yesterday bring us some much-needed good news: the Pfizer/BioNTech vaccine is very effective in preventing symptomatic and asymptomatic SARS-CoV-2 infection in healthcare workers!

SARS-CoV-2 variant: an update

PHE have published a rapid epidemiological comparison of the SARS-CoV-2 variant (VOC 202012/01 aka B1.1.7) with ‘wild-type’ SARS-Cov-2 in this country. Most of the characteristics don’t look to be different – the variant is not associated with more hospitalizations or an increase in 28-day mortality. However, there does seem to be an increase in secondary attack rates of the variant compared with wild-type SARS-CoV-2.
