Compared with when the epidemic began three years ago, the number of infected people now has much fewer severe cases than at the beginning. Many people infected now have mild symptoms, and some are asymptomatic. Although severe cases are much less common than before, they still exist. So how to judge? How long does it usually take after infection to appear? Although there are more and more people with Yang now, and many people are receiving treatment at home, they still cannot relax their vigilance and pay attention to severe cases.
Many people will have a fever after being positive. If there is no fever, does it mean that the condition is milder?
After becoming positive, the greetings between many people and friends became: "Do you have a fever? How high is the fever?" Whether you have a fever has become the criterion for many people to judge the severity of their symptoms. Does a high fever mean it is serious? Doesn't it mean it's not serious if it doesn't have a fever?
In fact, whether there is a fever is not the only criterion for judging the severity. Some people have better immunity and resistance . The symptoms after infection may be milder, and there is no fever, or the fever is not very high, and they do not need to take antipyretics, while some people have high fever. Generally speaking, although many people have a fever, it will return to normal in two or three days.
Compared with fever, everyone may also pay attention to the case of no fever, especially the elderly. Shu Huaqing, head of the Department of Critical Care Medicine at the West Campus of Union Hospital Affiliated to Huazhong University of Science and Technology, said that some elderly people do not have fever or cough, but they quietly become seriously ill.
But is there really no warning when it develops into a serious disease? No, it’s just that it hasn’t been noticed and taken seriously by patients. So, what warning signals does the body send out when the infection develops into severe disease? Which groups of people should pay more attention to?
According to the "Home Treatment Guidelines for People Infected with New Coronavirus " released in December, if the following situations occur, it may be an early warning of serious or critical illness, and you should seek medical treatment in time:
Your body temperature has been consistently higher than 38.5 for more than 3 days (and after drug treatment), your underlying diseases have significantly worsened, and you have difficulty breathing or shortness of breath.
For children , if persists in not eating, has difficulty feeding, lethargy, continues diarrhea and vomiting, it may be an early warning. For pregnant women, if they experience dizziness, palpitation, suffocation of breath, abnormal fetal movement, etc., they should also pay attention to it and seek medical examination in time.
For elderly people, people who have not been vaccinated against the new crown vaccine, and people with cardiovascular system and other diseases , the risk of developing severe disease after infection is relatively higher, and more attention is needed.
Among them, many elderly people are old and have varying degrees of cardiovascular disease. Their hypoxic response is relatively slow. If listlessness and loss of appetite occur, attention should be paid to it, as this may be a turning point in the progression of the disease.
After the elderly are infected, it is important to do the following two things:
The first thing is that if an elderly person in the family is infected, be sure to pay close attention and monitor some indicators , such as blood oxygen and heart rate . Seek medical attention in time when abnormalities occur, and do not take it lightly and think that it will be fine.
The second thing is that during the infection period, the elderly should pay special attention to appropriate and strengthen nutrition in their daily diet. Many elderly people usually eat too lightly and are already deficient in nutrients. If they do not pay attention to supplements at this time, their resistance will be easier to decline, and the probability of severe illness may be greater.
Many infectious diseases and intensivists have discovered that neglecting nutrition is a common feature of critically ill patients. They generally suffer from malnutrition problems.
hopes that elderly friends can avoid dietary misunderstandings, avoid absolute taboos, and keep up with nutrition, so that they can have a better physique to defeat the virus .Remind everyone not to eat any eggs or meat. They are a major source of good nutrition. For example, eggs contain high-quality protein. Timely and appropriate supplementation can help strengthen immunity and resistance. During this period, the elderly should treat rice as medicine.
Generally speaking, after being infected with new coronavirus , severe symptoms will develop. How long does it usually take after infection?
Professor Wang Guangfa, director of the Department of Respiratory and Critical Care Medicine at Peking University First Hospital, said that severe illness generally occurs within 5-7 days of infection.
Therefore, I would like to remind everyone not to relax, and do not think that it will not appear again after it has not appeared in the past few days. During the infection, you should rest more, and if you need to take medication, you should take it scientifically and standardizedly under the guidance of a doctor. Even if the test result turns negative a few days later, you still need to pay attention, because at this time the immune system is still disordered and has not returned to normal, and it takes time for the body to recover.
Young people should also pay attention after infection. Although young people have better physical fitness and are not at high risk of severe illness, there is a disease that is more common in young and middle-aged people, which is viral myocarditis .
Therefore, I would also like to remind some young friends to prevent this disease. During the infection period and after recovery, it is recommended that everyone pay attention to rest, do not stay up late, and do not rush to engage in high-intensity exercise. Don't overestimate your physical condition. If you experience any discomfort such as abnormal breathing or abnormal heartbeat, seek medical treatment in time when necessary. Don't just carry on.
In general, although the seriousness rate of the new coronavirus is much less than before, we still cannot underestimate it, and we cannot overestimate ourselves, especially for people with a relatively high risk of infection, we must pay more attention to it. During the infection, in addition to fever, sore throat, nasal congestion and other discomforts, the above-mentioned physical manifestations may be signs of severe illness and should be paid more attention to. Although many people with mild infection will get better in 5-7 days, this does not mean that the battle is over. After turning negative, you need to continue to maintain good living habits and continue prevention.
