Three in five long COVID patients have organ damage a year after infection

From this first set of scans, we found 331 participants (62%) had organ damage. Impairment of the liver, pancreas, heart and kidneys were most common (affecting 29%, 20%, 19% and 15% of participants respectively). These 331 participants were followed up six months later with a further MRI scan.

We found that three in five of the original study participants (59%) had impairment in at least one organ a year after infection, while just over one in four (27%) had impairment in two or more organs. So, for the vast majority of participants who had organ damage at six months, it was sustained until at least 12 months.

While in some cases participants with organ damage were no longer experiencing symptoms, organ impairment was associated with a higher likelihood of persistent symptoms and reduced function at 12 months.

Yes, masks reduce the risk of spreading COVID, despite a review saying they don’t

An updated Cochrane Review published last week is the latest to suggest face masks don’t work in the community.

However there are problems with the review’s methodology and its underpinning assumptions about transmission. Well-designed real-world studies during the pandemic showed any mask reduces the risk of COVID transmission by 50–80%, with the highest protection offered by N95 respirators.

Most long COVID cases had mild initial infections, UW study finds

Study found that a staggering 90% of people living with long COVID initially experienced only mild illness with COVID-19. After developing long COVID, however, the typical person experienced symptoms including fatigue, shortness of breath and cognitive problems such as brain fog – or a combination of these – that affected daily functioning. These symptoms had an impact on health as severe as the long-term effects of traumatic brain injury. Our study also found that women have twice the risk of men and four times the risk of children for developing long COVID.

China could face a catastrophic COVID surge as it lifts restrictions – here’s how it might play out

Given the low level of immunity in China, a major surge would likely see large numbers of hospitalisations and might lead to a dramatic death toll. If we assume, say, 70% of the Chinese population becomes infected over the coming months, then if 0.1% of those infected die (a conservative estimate ), a back-of-the-envelope calculation suggests we’d see around one million deaths.
