The virus is thought to spread mainly from person-to-person ... through respiratory droplets produced when an infected person coughs or sneezes.
A key issue for epidemiologists is helping policy makers decide the main objectives of mitigation—e.g., minimising morbidity and associated mortality, avoiding an epidemic peak that overwhelms health-care services, keeping the effects on the economy within manageable levels, and flattening the epidemic curve to wait for vaccine development and manufacture on scale and antiviral drug therapies.
As COVID-19 infections continue to escalate in the new year, some patients have been reporting a strange new symptom: night sweats. Commonly associated with other conditions like the flu, anxiety, or even cancer, night sweats were less commonly associated with COVID before the Omicron variant began to rapidly spread worldwide.
Night sweats are one of the symptoms of COVID-19.
The COVID-19 survivors showed multiple changes, including markers of tissue damage in areas linked to the brain’s olfactory centre. It’s not clear why this was the case, but one possibility is lack of input [...] Early in the pandemic, a study showed3 that the virus attacks cells in the nose, called sustentacular cells, that provide nutrients and support to odour-sensing neurons [...] compared with those who had been infected with the original virus, people who had contracted the Alpha variant — the first variant of concern to arise — were 50% as likely to have chemosensory disruption. This probability fell to 44% for the later Delta variant, and to 17% for the latest variant, Omicron.
For most people, smell, taste and chemesthesis recover within weeks. In a study published last July8, 72% of people with COVID-19 who had olfactory dysfunction reported that they recovered their sense of smell after a month, as did 84% of people with taste dysfunction.
There is strong evidence of brain-related abnormalities in COVID-19
The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales ... The main way the disease spreads is through respiratory droplets expelled by someone who is coughing.
