Sneak attack: how Covid-19 invades the heart, brain, veins and liver
Scientists are learning the contagion moves beyond the lungs, deep into the vascular system and even the brain
We think of Covid-19 as a respiratory virus, one that simply attacks the lungs. But scientists are now wondering if it is much more than that, with a stream of medical papers being published over the past few weeks that suggests the contagion can get deep into our vascular system and even our brains.
“We are seeing a range of illness; some people develop blood clots, others heart attacks or kidney failure,” said Dr Ajay Shah, a consultant cardiologist at King’s College Hospital, London. “There are still many unknowns, but the amount of research effort that is going on to understand exactly what is happening to patients with Covid is absolutely phenomenal.”
So how does the virus attack?..
