What is the reason for pneumonia symptoms after turning negative
?
Li Tong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital, once said that many people still have symptoms of cough and chest tightness two weeks after being infected with the new coronavirus. When they go to the hospital for examination, they are found to have pneumonia. There are two situations:
Some people have related pneumonia before, but they did not find it because they did not do CT. For young people with normal immunity , a little pneumonia can recover on their own.
Another reason is that after being infected with the new coronavirus, the defense ability of respiratory has declined, or because they did not have a good rest, their immunity is low and secondary bacterial infection occurs. In this case, symptoms of chest tightness, shortness of breath, worsening cough, and even fever may occur after 7 to 10 days.
After checking blood routine and taking chest CT, the doctor’s comprehensive judgment showed that if the original pneumonia is in the recovery period, you can continue to rest without treatment. If it is a secondary bacterial infection, antibiotic needs to be added to consolidate the treatment. Most people will recover quickly, so there is no need to worry too much.
What is "white lung"?
Does having pneumonia mean "white lung"?
Recently, the National Health Commission responded to the phenomenon of "white lungs" discovered in patients infected with the new coronavirus during medical treatment. Jiao Yahui, director of the Department of Medical Affairs of the National Health Commission, said that generally speaking, when lung inflammation is relatively severe and there is a lot of exudation, that is, the white image area reaches 70%-80%, which is colloquially called "white lung" in clinical practice.
The so-called "white lung" currently appearing has nothing to do with the original strain or vaccination. The existing mature expert consensus and treatment plan are mainly prone position ventilation and oxygen therapy, and strengthen the treatment of the cause of the original disease. A considerable number of patients with "white lung" can improve.
Compared with the original strain,
, does Omicron cause a lower proportion of pneumonia?
Ma Xiaochun, director of the Department of Critical Care Medicine at the First Affiliated Hospital of China Medical University, said that after the emergence of the Omicron strain , the overall pneumonia rate was significantly reduced compared with the original strain. Cases encountered before delta , including the original strain, had a higher overall incidence of pneumonia, and there were many patients who could not stop the progression of the disease with current intervention methods. Generally speaking, the disease progression of most patients infected with the Omicron strain can be stopped.
He Yingli, director of the Department of Infectious Diseases at the First Affiliated Hospital of Xi'an Jiaotong University, said that infections caused by Omicron cause relatively mild lung lesions, but may cause lung lesions in some high-risk and vulnerable groups. Before the epidemic of and new coronavirus , some patients with "white lung" were admitted every year. Non-new coronaviruses may also cause "white lung", and many patients can recover well after treatment.
Is pneumonia in the elderly caused by the new coronavirus
or is it a co-infection with underlying conditions?
Li Tong once said that some time ago, patients were mainly young people, but now the peak of infection in the elderly has begun to appear. Many of these elderly people have underlying diseases. They are prone to develop pneumonia after infection. The symptoms are usually obvious about a week after the onset of the disease and require hospitalization. There are several factors for the occurrence of pneumonia:
First, the elderly are relatively old. Most of the severe cases now are elderly people over 80 years old.
Second, the vast majority of patients have underlying diseases, such as hypertension , diabetes , and cardiovascular and cerebrovascular diseases . There are also some people who are complicated by bacterial infection in the later stage. The lung lesions are not the typical symptoms of viral pneumonia , but also mixed with the manifestations of bacterial pneumonia .
What symptoms do the elderly have?
Should we be more vigilant?
The immunity of the elderly is relatively poor, especially those who have not received the vaccine . Early symptoms include itchy throat, dry cough, and fever. The fever temperature may not be as high as that of young people. The peak body temperature will subside after three or four days.
But in the elderly, pneumonia often occurs on the fourth or fifth day when the virus reaches the lungs.At this time, some elderly people will experience chest tightness and shortness of breath, especially after activities. If the symptoms are ignored, the elderly will develop obvious hypoxia on the sixth or seventh day, and even experience shortness of breath and stuffiness when sitting quietly.
Doctor’s Tip: On the fourth or fifth day of infection, be sure to observe whether the elderly have shortness of breath, dizziness after activity, memory loss, sleepiness, confusion, or unsteady walking. If asthma occurs, seek medical attention immediately.
