How should asymptomatic infections of the new coronavirus be treated?

For COVID.

Almost all people infected with the virus need to be isolated**, but there are asymptomatic infections among those who are infected.

Novel coronavirus.

How should asymptomatic infections be carried out**? **The way for asymptomatic infections is probably isolation monitoring plus drugs**, and then regular nucleic acid testing.

to check if there is still a virus. In the early stage, it was probably through this kind of monitoring to determine whether the asymptomatic infected person is infectious or not, and whether he will have various clinical symptoms.

If the asymptomatic infected person is infectious, then it needs to be carried out**, the method is generally to kill the virus through drugs to **asymptomatic infection, because the asymptomatic infected person does not have any manifestations, and the body is also in a normal state, but it is infected by the virus, and the asymptomatic infected person of the new coronavirus in China also needs to go to the designated medical institution for isolation**, and cannot be at home **. According to the plan of isolation and monitoring in China, asymptomatic infections need to be isolated for 14 days, and if there is no clinical reaction during the isolation process, nucleic acid testing will be carried out again, and if the nucleic acid test is still positive, then isolation is still required**, until clinical manifestations appear, and a systematic all-round ** will be carried out.

If the nucleic acid test is negative after another 14 days of isolation**, then there is no need to ** again**, for how to carry out asymptomatic infections**, it is also necessary to rely on whether the infected population is infectious, and if it is infectious, it is necessary to have a blood routine.

The basic method for the determination of biochemical indicators and reactive proteins is to observe until the nucleic acid is negative, and then the isolation can be released. If the recurrence of the epidemic requires the use of antiviral drugs to deal with it, and asymptomatic infected people may also have a certain impact on the lungs, some **lung drugs may be selected in the process of isolation**.

Asymptomatic infection refers to the infected person without any clinical manifestations, in the face of this situation, it is necessary to go to the relevant designated hospital in time for some **, bed rest, and timely nutrition.

Seek medical attention in time, follow the doctor's instructions, take medications, recuperate for a period of time, the doctor observes your condition, and if you feel that it is almost enough, you can choose to be discharged.

This can be done by getting vaccinated and taking some medications. It is important to isolate these asymptomatic patients from those who are symptomatic.

As we all know, the new coronavirus infection is mainly affected by the lungs, and people infected with the new coronavirus usually experience symptoms such as poor breathing. At a press conference on the prevention and control of the new crown pneumonia epidemic, some experts pointed out that through relevant research results and the experience summarized by the medical treatment team, it is recommended that patients infected with the new crown virus choose to "sleep on their stomachs", which can make the patient's breathing smoother.

1. Experts say that sleeping on the stomach is an effective strategy for the new crown pneumonia, and the so-called sleeping on the stomach is "prone ventilation", which allows the patient to be ventilated in the way of lying on the stomach, which can better improve the oxygenation of acute respiratory distress syndrome and make the patient's breathing smoother. This **commonly used for ordinary and heavy**, has also become an adjunct to the new crown pneumonia.

2. According to experts, in fact, the human body's lung tissue is composed of many alveoli, about 60% of the lung tissue is close to the dorsal side of the human body, and there is a thin layer of lipoprotein in the alveoli that can reduce the tension of the alveoli. However, after the new coronavirus infection, the active substances on the surface of this layer will be destroyed, so that the gas cannot be evenly distributed in the alveoli, and the alveoli closer to the back side will be smaller under the action of gravity when lying on the back.

3. Sleeping on the stomach of patients infected with the new crown is mainly due to the action of gravity, and the water will go to a lower place, which is more conducive to drawing out the exudate in the alveoli of the dorsal test, thereby reducing the gravitational pressure of the heart and diaphragm on the dorsal lung tissue, promoting the uniform distribution of gas in the lung group, improving the exchange of qi and blood, taking away carbon dioxide, alleviating the symptoms of hypoxia, and protecting the lung tissue.

People infected with the new crown can choose to sleep on their stomachs, they can place two soft pillows on the chest or hip junction to better avoid abdominal compression, or they can put a soft pillow or U-shaped pillow on the head, and choose to sleep on their stomachs in the most comfortable posture of their stomachs. When sleeping on your stomach, if you feel uncomfortable or uncomfortable, it is best to tell your doctor in time so that you can take other ** solutions.

In addition, the duration of prone lying can be done gradually, and as the body slowly adjusts, it can be extended by more than 12 hours per day. Although sleeping on the stomach has an auxiliary effect on patients infected with the new crown, it is not suitable for all infected patients, such as those with unrelieved increased intracranial pressure, cerebral edema, spinal cord injury that has not been stabilized, clavicle fracture or facial fracture, severe burns, and severe arrhythmias, and it is not suitable to use prone ventilation.

The body temperature remained normal, and the rest of the symptoms were significantly reduced before returning to work and study. Older people with underlying medical conditions can rest for a few more days. If you really feel uncomfortable, you can also choose some targeted Chinese patent medicines.

1. Fever. Stay in bed, drink plenty of fluids, and eat light, easily digestible foods. In infectious fever, the fever itself is one of the manifestations of the body's immune system clearing the source of infection, and drugs such as antipyretics are usually not rushed unless there is a high fever and the patient is severely unwell.

Patients with high fever must be cooled, and the antipyretics of choice are acetaminophen and ibuprofen. (However, you can choose 1 kind of antipyretics, read the instructions carefully before use, and avoid repeating and overdosing; While taking acetaminophen, avoid drinking alcohol to prevent liver damage. ）

2. Cough. The symptoms are not particularly severe, so you don't need to take cough medicine. If the cough symptoms are very severe, and Layun has a tendency to have dyspnea or interferes with normal sleep and rest, cough suppressants can be appropriately taken for symptomatic treatment, including dextromethorphan hydrobromide tablets, dextromethorphan guaifenesin syrup, ambroxol hydrochloride tablets, acetylcysteine effervescent tablets, Lianhua Qingwen granules (capsules), Xuanlung Cough Mixture, Jingyin Granules, Phlegm Reqing Capsules, etc.

3. Decreased sense of smell or taste.

The incidence rate is not high, and most patients gradually recover their sense of smell and taste in about a week. This is not a symptom unique to the coronavirus, other respiratory viral infections can also occur. Brush your teeth twice a day to ensure oral hygiene.

If possible, olfactory training can be carried out according to the recommendations of the World Health Organization, including smelling lemons, roses, cloves and eucalyptus twice a day for 20 seconds each time. Try adding herbs and spices to your food, such as chili peppers, lemon juice, etc. However, caution is recommended for patients with concomitant diarrhea or plain gastrointestinal dysfunction.

1. Fever, usually cold fever will not re-heat after the human body returns to normal body temperature and the symptoms of anti-** fever appear, and the fever caused by the new coronavirus infection is recurrent and difficult to control with drugs.

In addition, there are a small number of people who have mild symptoms and no fever.

2. Dry cough, after the patient is infected with the new coronavirus, there will be symptoms of lung infection, among which dry cough is the most common, and some early patients will have slightly milder symptoms after taking antibiotics and other drugs by themselves, but the condition will worsen in a short time.

3. Fatigue, after the patient is infected with the new coronavirus, his respiratory system and digestive system are attacked by the virus, and his function decreases. At this time, the patient will have general weakness, and if no further medical intervention is carried out, it may lead to a variety of complications such as hypoxia, acute respiratory distress, sepsis, metabolic acidosis and other serious diseases.

4. Other atypical symptoms: such as digestive system symptoms: disturbed drinking, decreased appetite, lack of stool reputation, poor spirit, nausea and vomiting, diarrhea, etc. Neurological symptoms: such as headache. Cardiovascular symptoms: such as palpitation, chest tightness, etc.

Ophthalmic symptoms: such as conjunctivitis. However, there are also patients who only have mild muscle aches in the limbs or lower back, nasal congestion, runny nose and other cold symptoms.

Asymptomatic infection is a carrier of the new coronavirus. Asymptomatic infection refers to the absence of clinical symptoms such as fever, nasal congestion, runny nose, sore throat, cough, and chest tightness. , but the nucleic acid test result is positive.

Asymptomatic infected people have strong immunity and can not develop the disease for 14 days after being infected with the virus. If the virus is in their body for more than three weeks, there is a possibility of infection. If not detected and quarantined in time, there is a risk of community transmission.

First, there are current research results that show that the main source of infection is patients infected with the novel coronavirus. Asymptomatic or mild occult infection may also become a source of infection, because asymptomatic infection has relatively hidden clinical symptoms, making the infection in the novel coronavirus difficult to control and easy to cause the accumulation of the source of infection in the community. Second:

What if an asymptomatic infected person has symptoms of COVID? If you have symptoms of new crown pneumonia such as fever, cough, nasal congestion, runny nose, and chest tightness, you will become a confirmed case, indicating that the concentration of virus in the body will be very high, that is, you will become a carrier of new crown pneumonia. Therefore, asymptomatic infected people must be strictly isolated and observed.

At present, most of the Hong Laofan after the new coronavirus infection is mild or asymptomatic, but there are still a small number of infected people, including the elderly, especially the elderly who have not been vaccinated, and those with serious underlying diseases, who can be severely ill, or have aggravated the underlying diseases caused by modification.

The ninth edition of China's diagnosis and treatment protocol recommends the application of antiviral** to people at high risk of severe disease to alleviate symptoms, shorten the course of disease, and reduce the risk of severe disease and death.

There are three antiviral drugs before the hail, among which the new crown monoclonal antibody, which needs to be given intravenously and can only be used in hospitals. The other two small molecule oral antivirals are nirmatrelvir ritonavir combination and azvudine.

Nirmatrelvir ritonavir mixture can effectively reduce the risk of severe disease, the indication population is mild and ordinary, special attention should be paid to the interaction between drugs when using, such as the elderly and people with underlying diseases often take a variety of drugs orally, such as the use of simvastatin, lovastatin, amiodarone, etc. nirmatrelvir can not be used, and some drugs are relatively contraindicated, so it is recommended to use them under the guidance of a doctor.

Azvudine should not be used during pregnancy and lactation, and patients with moderate to severe liver and kidney impairment should also be used with caution, so it also needs to be used under the guidance of a doctor.

Antiviral drugs.

Can it be used for prophylactic purposes**.

Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital:

The elderly, especially those with underlying diseases and who have not been vaccinated, belong to the high-risk group, and should be detected and intervened early in the face of the epidemic. Some oral anti-coronavirus small molecule drugs can be used as soon as possible after the onset of illness or infection is clearly diagnosed, usually within 5 days.

This kind of anti-coronavirus small molecule drugs have the problem of interaction with many other drugs, and there will be some***, so it is important to use them under the guidance of a doctor. In addition, studies have shown that these drugs cannot be used for prophylaxis** and are not effective in patients with severe disease.

With antibiotics ** Covid is not very reliable. Antibiotics are ineffective against viral infectious diseases, and blind or inappropriate use of antibiotic drugs should be avoided when the new coronavirus is infected, especially the combination of broad-spectrum antibiotic drugs, so as not to cause dysbiosis, reduce one's own immunity or cause antibiotic resistance.

1. At present, the new coronavirus infection is usually dominated by asymptomatic and mild patients, and the main aspect is symptomatic**, such as ibuprofen sustained-release capsules, acetaminophen tablets and other antipyretic and analgesic drugs can be used when the fever is exceeded, and antitussive and expectorant drugs such as dextromethorphan hydrobromide tablets and bromhexine hydrochloride tablets can be taken to help alleviate the symptoms of cough and sputum.

At the same time, drink plenty of water, take reasonable rest, and generally do not need to use anti-infective drugs, and the condition will recover. If symptoms persist or worsen, you need to see a doctor.

2. If the patient infected with the new coronavirus is rechecked with blood routine, C-reactive protein and procalcitonin, and there are clear laboratory indicators to determine that the patient has bacterial infection, in this case, antibiotics can be used for antibacterial treatment. Antibiotics should not be misused without a laboratory diagnosis.

3. Novel coronavirus**, the first thing is symptomatic support**, generally** includes bed rest, ensuring that the patient has sufficient calories and maintains hydration

Electrolyte balance, timely monitoring of vital signs. Antiviral drugs can be used appropriately, including chloroquine phosphate tablets, arbidol hydrochloride tablets, ribavirin tablets, lopinavir ritonavir tablets, etc., and these antiviral drugs are not recommended to use more than three pulses at the same time.

Traditional Chinese medicine can be used for syndrome differentiation and treatment, and its effect is better, such as Lianhua Qingwen Capsule, Qingxuan Cough Granules, etc. On the basis of symptomatic, it is necessary to actively prevent the emergence of various complications, and to maintain a stable state of organ function, mainly to support.

4. Antibiotics, also known as antimicrobial drugs, refer to drugs for infectious diseases caused by pathogenic microorganisms such as bacteria, mycoplasma, chlamydia, rickettsia, spirochetes, fungi, etc., which have an inhibitory or killing effect on pathogenic bacteria, but generally have no effect on viruses.

The causative agent of the new coronavirus is a viral infection, and antibiotics have no killing effect on the new coronavirus. At present, there is no specific antiviral drug for the new coronavirus, and the main aspect is symptomatic and supportive. Most people with mild COVID-19 infection only need to take symptomatic treatment** and take relevant drugs to relieve their symptoms, and generally do not need to take antibiotics.
