Watch: From nose to toe, the Covid-19 virus attacks like no other ‘respiratory’ infection
The reports seemed to take doctors by surprise: The “respiratory” virus that causes Covid-19 made some patients nauseous. It left others unable to smell. In some, it caused acute kidney injury.
As the pandemic grew from an outbreak affecting thousands in Wuhan, China, to some 10 million cases and 500,000 deaths globally as of late June, the list of symptoms has also exploded. The Centers for Disease Control and Prevention constantly scrambled to update its list in an effort to help clinicians identify likely cases, a crucial diagnostic aid at a time when swab tests were in short supply and typically took (and still take) days to return results. The loss of a sense of smell made the list only in late April.
