COVID-19 symptoms

Blood clots. Purple toes. Kidney damage. Heart inflammation.

While COVID-19 is widely known as a respiratory illness, its roster of mysterious symptoms is pointing researchers to a surprising possibility—what if COVID-19 only begins as a respiratory infection, but ultimately becomes one that infects the blood vessels?

A Lancet paper published in April found that SARS-CoV-2 can launch vicious attacks on the lining of blood vessels.

Critically ill children have been ending up in intensive care units with shock-like symptoms in recent weeks, adding yet another mysterious layer to the coronavirus pandemic.

New York health officials began issuing alerts on May 4, describing young patients, ages 2-15, with inflammation in multiple organ systems and features of Kawasaki disease, a childhood illness of unclear origin. They raised the count to 64 suspected cases on May 6.

A few days earlier, officials in the United Kingdom notified doctors of similar cases there, also describing them as having features similar to Kawasaki disease and toxic shock syndrome. Several of the children had tested positive for COVID-19.

New research suggests that loss of smell as a symptom of COVID-19 may indicate a mild case of the disease.

A new study has found that loss of smell, which is a reported symptom of COVID-19, may indicate that a person will experience a milder case of the disease.

The research, which features in the International Forum of Allergy & Rhinology, may be valuable in allowing clinicians to identify which COVID-19 patients require hospitalization and which may be able to self-treat the disease at home.

How does the body respond when the SARS-CoV-2 virus infects it? Which physiological processes help or hinder us in getting rid of the virus, and which processes ensure that we have a mild form of COVID-19, the disease that the virus causes? In this Special Feature, we investigate.

The more we learn about COVID-19, the more we have to question our assumptions about it.

Early on in the COVID-19 pandemic, our information about the disease came from clinical case reports of COVID-19 and what we knew about influenza pandemics and the severe acute respiratory syndrome (SARS) resulting from SARS-CoV.

Clinicians are charting gruesome carnage in COVID-19 patients that extends far beyond the lungs, according to The Washington Post. Damage includes:

• Heart inflammation
• Acute kidney disease
• Neurological malfunction
• Intestinal damage
• Liver problems
  

A new study looking at the data of people who tested positive for COVID-19 backs up recent claims that the loss of the senses of smell and taste can be a symptom of the disease.

New research from the UC San Diego Health provides evidence that the loss of smell and taste can be a symptom of COVID-19.

Earlier this month, preliminary findings in a preprint started making headlines because they suggested that the list of possible COVID-19 symptoms should include the loss of smell and taste.
