From the very first grammatical case of the novel coronavirus reported inChina , doc knew the computer virus targeted the lungs . But now , doctors are seeing patient with severe symptoms who are develop other damage around the eubstance — from the kidney to the heart .
" While the lungs are kind of taking the brunt of it , because our unsusceptibility is so low to coronavirus , it ’s actually able-bodied to move around and distribute throughout our whole body , " pronounce Dr. Eric Cioe - Peña , an emergency room physician and the film director of global health at Northwell Health in New York who is also co - orchestrate a coronavirus treatment hospital at the South Beach psychiatric facility on Staten Island .
The coronavirus enters the body through therespiratory pamphlet — through the mouth or nose and into the lung — so to infect a person it needs to bond to an enzyme detect on the Earth’s surface of respiratory electric cell , Cioe - Peña said .

But once the coronavirus is in reality in the organic structure , it can get into the bloodstream , and from the blood stream , SARS - CoV-2 can travel to , and intrude on , other organ . " Once it ’s in thehuman body , it does n’t have a problem get into different types of cell , " Cioe - Peña told Live Science . That is " unfortunate because it causes all these other organ trouble . "
In treating severe COVID-19 patient in the emergency room , Cioe - Peña has seen patient develop viral myocarditis , or contagion of the bosom muscle . When one of his patients with COVID-19 undergoes sudden cardiac death , or a sudden death induce by warmheartedness problems , it ’s typically from infections around the heart , he added .
warmness trouble have been report in COVID-19 patient before . More than 1 in 5 affected role developed heart damage as a result of COVID-19 in Wuhan , China , one little study publish March 27 in the journalJAMA Cardiologysuggested .
SARS - CoV-2 can infiltrate both the bosom and the lung , because they each contain cells continue with the surface proteins have it off as angiotensin - converting enzyme 2 ( ACE2 ) , which serve as the gateway for the virus to enter cellular phone , Live Science antecedently reported .
Other organs also moderate this enzyme . The GI ( GI ) tract , for example , has many of these gateway — and its thought that the computer virus might be getting into other organ in a similar way .
Some patients who do n’t have respiratory symptoms instead experience Gb - pathway symptom , which means that the virus has infiltrated their small intestine and sometimes large intestines , Cioe - Peña said .
" And then we see elevated liver enzymes a bunch , " sometimes in modest cases , suggesting that SARS - CoV-2 is invading liver cell , he pronounce . When liver cellular telephone die , they slop their enzymes into the blood stream , he summate . But the liver is " fantastically good at regenerating , so there ’s believably no foresighted - term damage , " to the liver from the computer virus , he said .
Sometimes affected role also grow kidney loser , he said .
While some electronic organ equipment casualty is a effect of the virus straight off invade mobile phone , theimmune systemcauses much of the rest , Cioe - Peña tell . Cytokine storms — in which an army of resistant cells are released into the blood stream and then assault respectable tissues throughout the body — cause severe lung injury and can also cause multi - organ organisation failure , Cioe - Peña say . It ’s " an overwhelming response that essentially kind of shuts down our consistence . "
It ’s not unclouded why some people have such an elevated immune response compare with others , but some multitude could be genetically prostrate to it , Dr. Erin Michos , the associate director of preventive cardiology at Johns Hopkins School of Medicinepreviously told Live Science .
Such cytokine storm can even affect the brain , and some COVID-19 patients may have cytokine storms in the head , according to a previous Live Science report . What ’s more , loss of olfactory perception and appreciation have recently been added to the listing of possiblesymptoms of COVID-19 , which could suggest that the coronavirus might be able to encroach upon the nervous system and the part of the brain responsible for for the sense of olfaction , Live Science previously report .
Because there ’s currently no cure or specific treatment for the coronavirus , treatment at the hospital involves supportive maintenance for the affect organs .
It ’s not all bad news program . " In very , very severe cases , there ’s likely some lasting damage , " Cioe - Peña articulate . But " we ’ve picture grounds of people that have complete recovery . " The liver and kidney in picky can shut out down and then derive right back on and go back to normal .
Even with multifocal pneumonia , or pneumonia that affects more than one part of the lung , " we see a lot of people ’s chest of drawers 10 - rays and lung CAT scan give to normal , " he added . So for most people , " the Hammond organ are going to recover , as long as you survive the contagion . " That ’s even honest in patients with equipment casualty to the heart — an organ that ’s not as competent at regenerate as others . affected role who have myocarditis have a very high rate of mortality rate , Cioe - Peña said . But " most masses with essence equipment casualty from myocarditis fully recover , assume they survive . "
None of this is peculiarly surprising . In many computer virus , " we see a pot of organ liaison , " Cioe - Peña say . Any new virus that hops to humans , " can kind of go rampant in the trunk , " because our resistant scheme has n’t seen anything similar , he added . Once individuals develop some resistance to it , the multi - organ involvement will be less coarse , he tell .
It ’s still unsung how much immunity people who have recovered from the computer virus will have . But even if they do n’t gain full granting immunity , surviving the contagion once will likely mean someone has a less grave infection with less multi - organ affair the second time around , he said .
