Co-infection of Covid-19 and Influenza: How to distinguish?
Co-infection of Covid-19 and Influenza: How to distinguish? At the first China Health Technology Innovation and Development Conference held in Shenzhen, China’s top health expert Zhong Nanshan expressed his views on the latest research and judgment on the current COVID-19 epidemic.
During the prevention and control of the epidemic, 4 cases of influenza and COVID-19 have been detected, which also means that as the northern hemisphere enters winter, the emergence of influenza has once again increased the severity of the COVID-19 epidemic.
However, the current epidemic prevention and control measures can greatly shorten the flu season. Therefore, once a local case occurs, it is necessary to conduct national nucleic acid testing in certain areas. In addition, wearing masks can effectively prevent transmission, especially surgical masks or N95 masks. The diffusion of droplets and aerosols.
Not sure if it is flu or COVID-19?
After entering the autumn and winter seasons, due to the drop in temperature and dry weather, many infectious diseases began to occur frequently, such as flu and common cold.
These three types of diseases are somewhat similar in many symptoms, such as cough, fever, or fatigue. The symptoms of these diseases are very similar, so most people cannot distinguish between the three diseases.
Once the distinction is unclear, the corresponding treatment cannot be given, which will cause greater harm to the patient’s health and life.
Is there any difference between new coronavirus pneumonia, cold and flu?
What is the difference between new coronavirus pneumonia, cold and flu?
1. Novel coronavirus pneumonia
The cause of the new type of coronavirus pneumonia is only caused by infection with the new type of coronavirus. Once infected with the virus, patients will first show symptoms of fatigue, fever and dry cough.
Within 3 to 5 days after being infected with the new coronavirus lung, 50% of patients will have difficulty breathing, chest tightness, and suffocation. In addition, a small number of patients will experience diarrhea, sore throat, nasal congestion and runny nose.
When a patient with novel coronavirus pneumonia has a fever, the temperature will not be very high. Generally, low and moderate fever are the main ones, such as between 37.3 and 38.5.
If a severely ill patient develops, one week after the onset of illness, there will be very obvious hypoxemia and dyspnea, followed by systemic symptoms, such as metabolic acidosis, and multiple organ failures, which directly lead to death. .
2. the common cold
The common cold can occur all year round and is usually caused by infection with germs. If the patient’s body is over-fatigued, as well as lack of vitamin a, vitamin d, as well as cold, weakened immunity, it will lead to a cold.
After catching a cold, the patient will experience sneezing, watery nose, and a certain degree of nasal congestion. In the early stage, there will be slight dry and itchy pharynx. Generally, after 2 to 3 days of illness, the patient will have a sticky nose, a dull sense of taste, and a cough.
After suffering from a common cold, fever usually does not appear. If the fever is only a low-grade fever, it can be reduced by keeping warm or drinking some ginger syrup. As long as the physique is not very weak, it can usually heal itself within one week. .
Moreover, the common cold is hardly contagious.
Influenza is an acute respiratory infectious disease caused by infection with influenza virus, which is highly infectious.
After suffering from the flu, patients will quickly develop symptoms such as high fever, headache, fatigue, and body aches. Influenza patients can have a high fever of around 39-40 degrees, especially children.
There will be obvious symptoms of chills, chills, joint soreness, and sore throat during fever. If it is only a mild flu, it can be cured in 2 to 3 days; if it is a more severe flu, it can heal within 4 to 7 days after taking anti-fever and antiviral treatment.
How to distinguish the COVID-19, cold and flu?
Colds generally do not have a fever, and they can be cured by taking proper rest and keeping warm. The onset of influenza is rapid, high fever, accompanied by muscle aches, joint pains and headaches, and loss of appetite. Therefore, fever reduction and antiviral treatment are needed to heal.
In the first three days of the new coronavirus, only mild dry cough, fatigue, and low-grade fever will occur. Subsequently, within 5 to 7 days, it will quickly turn to pneumonia or severe pneumonia, causing the patient to have difficulty breathing, multiple functional failures, and a very high mortality rate.
For patients with the common cold and flu, a simple fever and antiviral treatment can be used to quickly cure them, with almost no harm to the patient’s life.
For patients with new coronavirus pneumonia, it is necessary to pass symptomatic and supportive treatment and isolation treatment to achieve a cure.
Therefore, the epidemic is not over yet, and prevention and control measures cannot be slackened.
Therefore, in addition to wearing a mask, washing hands frequently, and personal protection, you also need to keep the indoor air ventilated, and try not to gather in a sealed space for a long time.
Although current influenza vaccination has not been able to directly prevent the new coronavirus infection, influenza vaccination can effectively reduce the rate of influenza infection and reduce the incidence of severe cases, especially for key and high-risk populations. It is necessary to do a good job of vaccination before the flu season. .
