Corona virus remains in the lungs even after recovery

The new Novel Coronavirus disease affects the respiratory system, during which most patients experience a dry cough and fever with difficulty breathing.

That is, it affects the lungs the most, and now scientists have discovered that the virus may be present in the depths of the lungs of people recovering from code 19.

The study, published in the journal Cell Research, found that this may be the reason why some patients are re-diagnosed with the virus after recovery.

Scientists involved in the study, from China’s Army Medical University, said it was the first time that evidence of the virus had been found in the lungs of a patient who had three consecutive negative tests.

The results of the study were compiled from the postmortem of a 78-year-old patient who had contracted the corona virus and was treated.

After treatment, she recovered and had negative results in 3 tests, but died a day later due to sudden cardiac arrest.

The postmortem found no signs of the virus on vital organs such as the heart, liver and skin, but some types were discovered deep in the lungs.

The study came after repeated tests in several people who had recovered from the virus in South Korea and China confirmed it.

In fact, in some people the virus was confirmed 2 months after the initial negative test.

Much work is being done to develop immunity to the virus among infected people, as experts believe it is the key to opening up countries after the lockdown, but the World Health Organization warns that there is no evidence that Once infected with the virus, the infected person cannot become infected again.

Tim, who was involved in the Chinese study, said the results showed that coronavirus infections needed to be diagnosed immediately.

Earlier in March, a video of the lungs of a Corona virus patient at George Washington University Hospital in the United States was shared on YouTube, showing healthy lung tissues in blue and virus-infected tissues in yellow. ۔

Dr Keith Mortman, head of the hospital’s breast surgery department, said: “It’s amazing to see a combination of healthy and infected lung tissue. In fact, you don’t need a medical degree to understand that The damage to the lungs is not limited to one part, in fact it causes severe damage to both lungs.

“It can damage the lungs of people recovering from code 19 on a long-term basis,” he said.

Earlier, in mid-March, medical experts in Hawking Kong discovered that people recovering from the new novel corona virus could have weakened lungs and some people could have shortness of breath when walking fast.

According to the South China Morning Post, the Hong Kong Hospital Authority came to this conclusion after examining the initial patients recovering from coronavirus disease code 19.

Doctors found changes in the lung capacity of 2 to 3 out of 12 patients.

Dr. Owen Tsang Tak Yin, medical director of the hospital’s Infectious Diseases Center, told a news conference: “These people have shortness of breath when they walk a little faster, while some patients have 20 to 30 lung functions after complete recovery. The percentage may decrease.

He added that it was too early to determine the long-term effects of the disease, but a scan of the lungs of nine patients revealed a dust-like pattern on the glass, indicating organ damage.

He said further tests would be performed on these patients to determine the extent to which their lungs were functioning, while physiotherapy would be arranged to strengthen the lungs.

The doctor said that recovering patients can help their lungs to fully recover gradually through various exercises such as swimming.

A later study in China found that if the disease was more severe, patients would have a general accumulation of fluid in the lungs, which was similar to cases of pneumonia, and could be detected by a CT scan. There are white marks on the lungs, which the doctor calls ground glass.

Research at Tongji Hospital in Wuhan (the city where the virus began to spread) examined CT scans of the chests of hundreds of patients.

According to research published in the journal Radiology, the analysis revealed a ground glass infection, in which the airways in the lungs become filled with fluid while the tiny cells in the lungs (which exchange oxygen and carbon dioxide molecules with the blood), Is damaged.

These ground glasses appear as blurred drops on a CT scan, which changes shape as the disease worsens, as you can see in the small yellow arrows on the CT scan below.

This fluid is not only specific to the corona virus but is also found in a variety of infections and lung diseases, but its structure and distribution are specific to code 19.

The study involved more than a thousand patients and found that a CT scan of their chest was the most effective way to diagnose code 19 compared to lab tests.

Serious p of code 19 Complications appear as a result of pneumonia which results in difficulty breathing, lack of oxygen levels in the body and coughing, gradually the lungs are unable to absorb the right amount of oxygen from the bloodstream.
