The One COVID Symptom Everyone Gets Most

  The One COVID Symptom Everyone Gets Most A new study joins earlier research in suggesting that one symptom of coronavirus (COVID-19) is most common: Fever.In a study published Nov. 9 in The Journal of Emergency Medicine, scientists looked at nearly 12,000 people who were tested for COVID-19 at emergency rooms around New York City. In that group, the most common symptoms that accompanied a positive COVID test were: fever (74%), shortness of breath (68%), and cough (65%).

One of the most mysterious—and alarming—consequences of COVID-19 is the neurological damage the virus can cause. Some of those infected with the novel coronavirus have reported a wide variety of brain-based symptoms, from headaches and dizziness to delirium and depression. Doctors like Dr. Mary Fowkes, a neuropathologist at Mount Sinai Hospital in Manhattan, have discovered "significant" blood clots in the brain.

These Scary COVID Symptoms Seem Neverending, Says Study

  These Scary COVID Symptoms Seem Neverending, Says Study Many of COVID-19 survivors are experiencing hardship months after being released from the hospitals—with many of them struggling to return to “normal.”Dr. Vineet Chopra of the University of Michigan Health System led a team of researchers following 1648 individuals who were hospitalized with the virus. Of them, they focused on 488 Covid-19 patients who were treated and released from the hospital between March 16 and July 1, and available for a follow-up 60-day postdischarge telephone survey.

A route to the brain

Originally, scientists theorized that the novel coronavirus attacked the brain directly. Some studies have suggested that may not be so, that COVID-19 affects certain neurons instead of the brain itself.

New research published Monday in the journal Neuroscience posits a potential pathway for the virus to the brain: Through the nose.

Analyzing autopsies of people who died of COVID-19, researchers in Berlin found that the virus was evident in nerve endings deep in the nasal passages, "where the throat meets the nasal cavity, and where odor receptors and perceptual cells converge," the New York Times says.

From there, the virus can invade the nervous system via nasal tissue that is in close connection with the body's neurological network, the scientists posit.

The virus may be "able to use the olfactory mucosa as a port of entry into the brain," said Dr. Frank Heppner, a neuropathologist at the Charité-Universitätsmedizin in Berlin and a co-author of the study.

Several studies have found that the coronavirus can have long-term neurological effects. An August study published in the Lancet found that 55% of people diagnosed with coronavirus reported neurological symptoms three months after their diagnosis, including confusion, brain fog, an inability to focus, personality changes, insomnia and loss of taste and/or smell.

In July, researchers at the University College of London said the coronavirus could cause "an epidemic of brain damage," referring to a similar phenomenon that occurred after the 1918 flu pandemic, which was also caused by a coronavirus.
