The new coronavirus began to spread from animals to humans at the end of last year. So far, there have been more than 2 million confirmed cases worldwide.
Although many of these patients have recovered, there are signs that some patients may take a long time to completely return to normal.
How long it takes for the body to recover after being infected with a new crown depends on many factors. First of all, it depends on how heavy your illness is. Second, we must also consider age, gender, and whether there are other health problems, because if a person has a basic disease, it will increase the risk of serious illness.
In addition, it also depends on the treatment you receive. The more invasive the treatment, the longer it takes, and the longer the body needs to recover.
The severity of symptoms also affects the time required for recovery
What if it is only mild?
Most patients infected with the new coronavirus will have the main symptoms of fever and cough. But it may also be accompanied by body pain, fatigue, sore throat, and headache.
It is usually dry cough at first, but some people may eventually cough up sputum with lung cells killed by the virus.
If this is the case, just rest in bed, drink plenty of water and take paracetamol analgesics.
Mild patients should get better soon. It usually takes less than a week to reduce the fever, but the cough may continue for some time.
According to a study by the World Health Organization WHO on Chinese data, it can recover in an average of two weeks.
What if the illness is more serious?
Some people will have more severe symptoms. It usually gets worse about 7 to 10 days after onset.
Moreover, this shift will happen suddenly. Difficulty breathing will occur, and the lungs will become inflamed.
This is because the body's immune system attempts to fight the virus, but sometimes the immune system responds excessively, which can cause damage to other parts of the body.
Some people will need hospitalized oxygen therapy for this.
British family doctor Jarvis explained that if shortness of breath occurs, it will take a long time to slowly improve. This is because your body needs to recover from injury and inflammation. This process may take up to two to eight weeks.
Even so, there may be a long time when the body still feels tired.
France provides rehabilitation services for new crown patients
What is the impact of intensive care on rehabilitation?
According to WHO estimates, one in every 20 patients needs to be admitted to the intensive care unit for treatment, including the use of a ventilator after anesthesia.
Regardless of the disease, as long as the intensive care treatment requires a long period of rehabilitation to recover.
After coming out of the intensive care unit, patients still need to observe in the general ward for a period of time before being discharged home.
Intensive care expert Pittard said that it usually takes 12 to 18 months for such patients to completely return to normal.
In addition, long-term hospitalization in a hospital bed can cause muscle loss. The patient will be very weak, and muscle recovery will take time. Some people even need physical therapy to help them "learn".
Not only that, patients who have undergone intensive care treatment have the possibility of developing mental and psychological problems.
Tuos, an intensive care nurse therapist in Cardiff, Wales, explained that post-viral fatigue syndrome has a huge impact on the late recovery of new crown patients.
Reports from China and Italy show that many patients with severe illnesses have generalized weakness, including shortness of breath with a little effort. It is also accompanied by persistent coughing and breathing problems. It also requires a lot of sleep.
Tuos said that some patients take a long time to recover, which may be several months or even longer.
Of course, it cannot be generalized. Some people have received treatment in the intensive care unit, but the relative time is relatively short; others require ventilator treatment for up to several weeks, and naturally recover differently.
Will the new coronavirus have long-term health effects?
We are not sure whether the new coronavirus will have a long-term impact, because we lack data in this regard. But we can refer to other situations.
Some patients suffer from acute respiratory distress syndrome (Ards) during their illness, which means that their immune system reacts excessively during the fight against the new crown disease, causing damage to the lungs.
Tuos said that data in this area shows that even after 5 years, people still have persistent physical and psychological discomfort.
Dr. Kiel of Warwick Medical School said that people also need psychological support to help them recover. He said that it is conceivable that when patients have difficulty breathing, doctors need to use a ventilator to rescue them.
The doctor will tell the patient, "We are going to put you on a ventilator. We will give you anesthesia to let you sleep. Do you want to say goodbye to your family?"
It is not surprising that some critically ill patients later develop post-traumatic stress disorder (PTSD), which will cause severe psychological trauma to many people.
Even some mild patients have the possibility of long-term health problems, such as fatigue.
