Is a cold a reinfection with a cold virus or an attack of a cold virus in the body?

Getting cold only leads to low resistance, at this time, if the virus invades, it will be easy to catch a cold, the virus mutation ability is very strong, every cold is caused by the invasion of different viruses, so you will produce different kinds of antiviral antibodies.

Colds are not necessarily caused by viruses, some are caused by a cold or when the body is in a relatively hot environment and the internal environment is damaged. When the body's immune function declines, it is easier to lead to the invasion of cold viruses, affecting the normal work of immune cells, and causing cold symptoms. After catching a cold, you must pay attention to your own protection, avoid going to crowded places, and pay attention to washing your hands frequently.

70% and 80% of the common pathogens of upper respiratory tract infections are viruses, including parainfluenza virus, respiratory syncytial virus, adenovirus, rhinovirus, echovirus, coxsackievirus, and measles.

viruses and rubella viruses, etc.

Bacterial infections. Approximately 20% to 30% of the total, bacterial infections can be either directly or secondary to viral infections.

After that, hemolytic streptococcus was the most common, followed by Haemophilus influenzae, Streptococcus pneumoniae and Staphylococcus, and Gram-negative bacilli were rare.

Essential**. Take nasopharyngitis.

It is the manifestation of the "common cold": most of them are caused by rhinovirus, but they can also be caused by coronavirus, parainfluenza virus, respiratory syncytial virus, echovirus, coxsackievirus, etc.

Upper respiratory tract infections with pharyngitis as the main manifestation mainly include:

Acute viral pharyngitis: mainly caused by influenza virus and adenovirus.

Acute viral laryngitis: often caused by influenza virus, rhinovirus, parainfluenza virus, or adenovirus.

Herpangina.

Mainly caused by coxsackievirus A.

Pharyngeal conjunctival fever: mainly caused by adenovirus and coxsackievirus, it usually occurs in summer and spreads during swimming.

Pharyngeal-tonsillitis.

It is mainly caused by hemolytic streptococcus, but can also be caused by Haemophilus influenzae, Streptococcus pneumoniae, Staphylococcus, etc.

The common cold is generally caused by the upper respiratory tract bacterial or viral infection, most of which is caused by viral infection, so if this situation occurs, it is recommended to choose some antiviral **, the best is to show symptoms, and some antiviral drugs are the best. Drink plenty of boiled water, pay attention to rest, and regularly review the blood routine, and the condition will be improved.

The common cold is not a virus, and the common cold is divided into wind-heat cold and wind-cold cold. Viral colds are caused by illness. It is the cold caused by the poison that becomes the virus **. There is a viral infection in the blood. Neutrophils are high.

The common cold is the most common disease in acute upper respiratory tract viral infection, which is mostly self-limited, with a relatively high incidence and sporadic.

It occurs all over the world, can occur all year round, increases in winter and spring, and the pathogens that can cause it mainly include adenovirus, respiratory syncytial virus, influenza virus, parainfluenza virus, enterovirus, mainly through coughing and sneezing, transmitted by respiratory droplets, and is more likely to be infected in a densely populated environment.

The common cold is mostly caused by a viral infection. It is different from the flu. A cold or fire is the trigger.

Viruses that cause colds, such as rhinovirus, adenovirus, respiratory syncytial virus, coronavirus, coxsackievirus, influenza and parainfluenza viruses.

In addition, colds are self-limiting, and they can be healed by rest and nutrition supplementation, but for more severe colds, antiviral drugs should be used in a timely manner, which are some broad-spectrum antiviral drugs, such as ribavirin, oseltamivir, etc.

The common cold is indeed caused by this virus, so there is no specific medicine for colds, just symptomatic**Drink more warm water.

Most of the common cold is caused by a virus, so don't take antibiotics if you don't have complications.

The common cold (also called a cold) is caused by cold viruses, including adenoviruses (also called rhinoviruses) and some coronaviruses. Colds can only be caused by cold viruses, and nothing else can cause them.

This kind of cold is not caused by a virus, so there is no need for antiviral oral liquid, just take cold medicine, or sweating can relieve it.

In winter, when the weather is cold, many people will have symptoms such as nasal congestion, runny nose, and itchy throat. What is the difference between the three without antigen or nucleic acid testing? In this regard, experts said that the infection caused by the new crown virus is more transmissible and contagious.

The common cold is generally the first branch, and for people who do not have any underlying medical conditions and have normal immune function, the symptoms can be quickly relieved. Epidemic symptoms are more severe because it is associated with influenza virus infection, which may cause more severe systemic symptoms, such as fatigue and body aches. In addition to respiratory symptoms, the symptoms of this systemic infection, such as fatigue, body aches, sore throat, including subsequent cough and sputum production, are more severe than those of the flu.

You must pay attention to these when you are yang.

1. Don't mix all the drugs together, the properties of the medicine are different, adverse reactions may occur, you must know that in different environments and different physical states, the same medicine may have different effects.

2. Sleep more, the body can repair itself, the immune system is fully mobilized, the garbage bags in the house and the toilet should be changed, and the cough and phlegm should be wrapped up and then thrown away, so as to prevent the cycle from damaging the house environment and prevent pollution to the house and the home environment.

3. During the illness, it is necessary to keep eating, maintain nutritional intake, achieve less salt and less oil, light diet, control sugar and limit alcohol, and ensure sufficient boiled water or electrolyte water.

4. After the fever, it is necessary to pay more attention to the cold and keep warm, the body has experienced the battle of high temperature, although the body surface temperature is normal, but the temperature of the viscera and bone marrow is still slightly higher. The overall energy of the body is in a state of exhaustion, pay attention to protection to prevent secondary infection.

A cold can be a viral infection or a bacterial infection.

Among the common pathogens that cause colds, viruses account for about 70%-80%, including parainfluenza virus, adenovirus, echopathic rangkai virus, coxsackievirus, etc., and colds caused by viral infection are called viral infections. Symptoms such as nasal congestion, runny nose, sore throat, cough and so on can occur, most of which are mild and self-limited, and some patients with severe symptoms may need to be given anti-ascending virus drugs.

Bacteria account for about 20%-30% of the pathogens that cause colds, and common pathogenic bacteria can include hemolytic streptococcus, pneumoniae streptococcus, Haemophilus influenzae, etc. Colds caused by bacterial infections can cause symptoms such as high fever, chills, cough, sore throat, etc., which can be treated with antibacterial drugs with a smile.

Whether it is a cold caused by a viral infection or a cold caused by a bacterial infection, it should not be taken lightly, and it is recommended that it should be done as soon as possible**.

1. Viral infection is an acute upper respiratory tract infectious disease caused by a virus, including the common cold, epidemic infection, viral angina, etc. It is mainly transmitted through the nose through air, droplets, or hand contact. Epidemic is an acute respiratory infection caused by influenza disease, and the virus is present in the respiratory tract of patients.

It is transmitted by droplets when the patient coughs or sneezes. Due to its strong contagiousness and rapid transmission speed, the Kongzheng section is difficult to control and can easily cause an explosive epidemic.

2 The common cold is caused by rhinovirus, coronavirus and parainfluenza virus, which are present in the respiratory tract of patients and transmitted to others through droplets. The common cold is epidemic** The contagiousness is much weaker, and it is generally easy to get sick after being cold, rainy, and fatigued, so that it is easy to get sick. Epidemic ** outbreak is generally caused by influenza A and influenza B, and influenza is very contagious, so it generally appears in batches, and even causes an outbreak epidemic.

3. The main manifestations of the virus are sneezing, nasal congestion, runny nose, dry throat, sore throat, cough, hoarseness and other symptoms, and the whole body manifests headache, body aches and fatigue, with or without fever and other symptoms, and the transmission route is generally through sneezing, droplets, saliva, coughing, and talking to spread the virus into the air to infect others. Healthy people can also get sick from the virus due to the use of the patient's hair, basins, utensils, etc.

4. The main pathogen of the virus is the virus, and the virus has self-limiting characteristics, so the general common cold, the symptoms are mild, and you don't need to take medicine, as long as you rest more, drink more water, strengthen nutrition, pay attention to ventilation, and can also heal yourself, and the course of the disease is generally five to seven days. If the symptoms are more severe, the common cold and epidemic**, take antiviral** as soon as possible to shorten the course of the disease and reduce symptoms such as general malaise.

1. Viral infection is an acute upper respiratory tract infectious disease caused by a virus, including the common cold, epidemic infection, viral angina, etc., which is mainly transmitted through the nasal cavity through air, droplets or hand contact.

Epidemic is an acute respiratory infection caused by influenza virus, the virus exists in the respiratory tract of the patient, and is transmitted by droplets when the patient coughs and sneezes.

The common cold is caused by rhinovirus, coronavirus, and parainfluenza virus. The common cold is much weaker and more infectious, and it is often individual, and it is easy to get sick when the body's resistance is reduced.

2. The virus can heal itself, so you don't need to worry too much.

Most of the clinical manifestations of this cold symptom are swelling of the nasal mucosa, resulting in nasal congestion, runny nose, cough, spitting, headache, itching in the throat or a painful feeling, if it is an epidemic, it is mainly manifested as general weakness, muscle soreness in the limbs, nausea and other symptoms, no matter which kind of cold can be healed by itself, drink more water, pay attention to rest, measure body temperature twice a day, avoid staying up late, eat more fresh vegetables and fruits, which will help the body recover.

3. Viral infection is mainly an acute upper respiratory tract infectious disease caused by a virus, which is self-limiting. If the patient has a mild cold, the cold patient can not need infusion**, if the patient has poor mental condition, poor appetite, fatigue, nausea, vomiting, diarrhea and other symptoms, can consider infusion, antiviral rehydration**.

4. If there are no complications caused by the virus, the common viral infection caused by the cold, generally three to seven days can recover on its own, itself is a self-limiting, infectious disease with the elderly, drink more water during the cold, maintain the temperature and humidity of the indoor air, do not eat chili, seafood, fried, pickled and smoked food, eat more vitamin-rich fruits and vegetables. And we should establish confidence in defeating the disease, and control the daily water intake at about one to two liters, which can effectively promote the body's metabolism and help restore function.
