COVID-19 has now begun to show newer symptoms and syndromes

COVID-19 isn't just a respiratory disease that has been ravaging the entire world. It hits the whole body, according to recent findings.

The most obvious symptoms of the infection are classic respiratory symptoms -- fever, pneumonia and acute respiratory distress syndrome. But the virus also seems to attack some organs directly.

The virus seems to affect thrombosis and to directly affect your blood vessels -- implying it can stand to affect the entire body.

CNN.com quoted an example of a patient who had been relatively fine for the first 10 days he was down with COVID-19 to further its research on the various side-effects and syndromes caused due to the deadly virus.

Just 38, he had mild pulmonary symptoms that he was just sitting at home with, and just had a little cough.

"Then he just woke up with both his legs numb and cold and so weak he couldn't walk," Dr Sean Wengerter, a vascular surgeon in Pomona, New York told CNN.

The young man had an aortic occlusion -- a big blood clot in the body's main artery, right above where it splits into two parts to run into each leg. Blood was not getting into the iliac arteries and his legs were being starved.

This was just one of the many examples that tell of the odd and frightening syndromes, including blood clots of all sizes throughout the body, kidney failure, heart inflammation and immune complications doctors are observing in people who have contracted coronavirus.

In some cases it's having severe effects on the patient's ability to breathe, and in others it seems to be associated with development of multi-system organ failure.

It's also associated with immune effects in children.

Another syndrome is the attack on the lining of the blood vessels, which in turn causes unnatural blood clotting.

There have been reported unusual strokes in younger patients, as well as pulmonary embolisms.

Pathologists are finding tiny blood clots in the smallest vessels.

One of the most frightening syndromes that might be linked with Covid-19 is "pediatric multisystem inflammatory syndrome.

It is characterised by persistent fever, inflammation, poor function in one or more organs, and other symptoms that resemble shock, a panel of pediatricians known as the International PICU-COVID-19 Collaboration says.

In some cases, children show shock and some have features of Kawasaki disease.

"It is even possible that the antibodies that children are making to SARS-CoV2 are creating an immune reaction in the body. Nobody knows," said Dr Jane Newburger, a cardiologist on the Boston Children's panel and an expert on Kawasaki disease.

Cytokine storm may also cause some of the lung damage and unusual blood clotting seen in adult patients.

One last symptom is known as "Covid toes." Patients are reporting red or purple swelling of their toes. It's possible the tiny blood clots associated with COVID-19 are causing it.
