While global figures vary, it is thought that about 14 per cent of people who catch covid-19 end up with lasting symptoms – which is some 25 million people worldwide. For some, symptoms have persisted for over a year. #LongCovid
One puzzling feature is that those most prone to #LongCovid aren’t those most likely to get sick from the initial infection. Women are 30 per cent more likely to get it than men, and 35 to 69-year-olds are the age group most often affected, according to the @ONS.
One report suggests people with #LongCovid can be divided into four groups: those experiencing the after-effects of ventilation in intensive care; those with organ damage caused by the virus; those with post-viral fatigue syndrome; and a miscellaneous group with varying symptoms.

All life on Earth depends on nitrogen, but because of human activity, the nitrogen cycle is now dangerously out of whack. Here are five ways that nitrogen pollution is harming our planet. (Thread...) Image
1. Rain can wash nitrates into watercourses and oceans. This nitrogen-based pollution feeds algal blooms that suck up oxygen as they decompose, choking aquatic life. Image
2. Cars and power plants emit nitrogen oxides, which are one of the principal precursors to a type of air pollution called particulate matter. These tiny particles can be breathed into our lungs, where they cause tissue damage associated with a range of health problems. Image
