What is the cause of a low grade fever that persists for a week after a cold and cough? Hurry, hurry

The cold hasn't healed yet. Cough and low-grade fever are signs that the cold has not been cured. In fact, now the cold can be cured quickly by itself, and there is no need for medication at all.

Three factors directly determine whether the human body will catch a cold and have a fever:1whether the virus has entered the body; 2.The amount of virus that enters the human body is large; 3.The virus that enters the human body has a certain virulence.

So what about these viruses that enter the body from **? - Nose. The air we breathe is filled with viruses, bacteria, and fungi.

When we breathe, the virus enters the nasal passages with the air flow and is captured by mucus. If the nose is properly detoxified, the virus can be transported to the nasopharynx within 15 to 30 minutes, and then slid into the stomach to be digested, keeping the amount of virus in the nasal cavity within a certain range. However, if the inducing factors such as cold, rain, excessive fatigue, etc., the nasal detoxification ability is reduced, the time for the virus to stay in the nasal cavity increases, and the virus can multiply the number of viruses with pathogenic ability, and the nasal cavity itself cannot cope with it, and a large number of viruses will invade the human body and cause disease.

This is more pronounced in patients with rhinitis and in people who are in their menstrual period such as menstruation and pregnancy.

At this time, the nasal cavity becomes the base camp for the virus to invade the human body. The virus continues to multiply in the nasal cavity and enter the body fluids through the nasal mucosa, and spread to the whole body with the body fluids, and the symptoms of the corresponding parts are gradually manifested. If the number of viruses invading the human body is too large and the virus has a certain degree of virulence, the human body temperature will begin to rise, which is more conducive to the human immune system to kill the virus.

If the amount of virus that enters the body is not very large, it shows symptoms of a common cold without fever. (But due to drug abuse, colds and fevers are becoming more common.) ）

Therefore, the most important thing to bring the body temperature down is to reduce the amount of virus that enters the body. Once you've found this, the solution is simple. Buy yourself a nasal wash pot and wash your nose with warm salt water.

Wash when you have nasal mucus, so that you can continuously reduce the virus in the nasal passages, so that less virus has a chance to enter the body, and finally reduce the amount of virus in the nasal passages to a safe range. At the same time, drink plenty of water and constantly dilute the virus that has entered the body to reduce symptoms. The virus that enters the body loses the replenishment of the new virus, and the weakened effect of the immune system is quickly eliminated.

At this point, the disease is cured.

In this way, after catching a cold, it is reduced to nasal washing in the morning and evening, which can slowly regulate nasal tissues, and **rhinitis.

And the best way to ensure a healthy life is not to take no medicine to treat the disease after getting sick, but to do a good job of prevention. Thorough cleaning of the nasal passages with warm salt water in the morning and evening can reduce the amount of virus in the nasal passages and prevent illness from occurring in the presence of precipitating factors. During influenza-prone periods, a nasal wash can also wash away possible influenza viruses and avoid influenza infection.

Since the pathogenic principle of various influenzas and colds is the same, this method is suitable for all kinds of influenza and colds.

First of all, don't be in a hurry. It means that your cold is not completely healed.

This year's cold is time-consuming and troublesome.

Other tests showed no other diseases.

As long as you still treat it like a cold: take medicine, rest, drink plenty of fluids, boost your nutrition, and keep warm.

The body will recover gradually. It takes time to heal a disease, and it takes a process.

May you get back to health soon!

The cough does not stop after a cold, and it can even last for two or three months, so it should be noted that these four reasons may be the same.

Low-grade fever can occur for many reasons. The main cause is infectious low-grade fever. This is the most common in life, accounting for about 40%, and among all infectious low-grade fevers, tuberculosis bacteria infection is the most.

Tuberculosis infection is characterized by low-grade fever in the afternoon, which may also be accompanied by cough, fatigue, and sweating at night or after waking up. Long-term low-grade fever caused by chronic biliary tract infection, chronic urinary tract infection, chronic pelvic inflammatory disease, chronic otitis media, chronic sinusitis, subacute endocarditis and viruses is also common.

It is recommended to go to the hospital as soon as possible for examination and diagnosis.

Tuberculosis infection is suspected and does not necessarily have a lesion. You need to go to the hospital to do a tuberculosis test.

Virus infection throat or lungs, if not the physique is very weak, it has always been so, most of the symptoms of the virus **, now the symptoms of the flu are not the same, some runny nose, sneezing, some headache, dizziness, some persistent low-grade fever, muscle aches, etc., but it is best to go to the hospital for examination, so as to confirm the diagnosis, in short, you should take anti-inflammatory drugs or injections to reduce inflammation.

High fever**.

1?Infectious diseases.

It is caused by bacterial, viral, protozoan infection, which is the most common cause. Such as colds, pneumonia, bronchitis, malaria, etc.

2?Non-infectious diseases.

Heat stroke, tumors, immune diseases such as lupus erythematosus, rheumatoid, etc. It is recommended that you go to a regular hospital as soon as possible to do relevant examinations, find out**, and treat the symptoms**, so as not to delay the condition.

Problem Analysis:

Hello, when there is a patient's persistent ** and cough, the infusion is caused by an acute respiratory infection. Symptoms of a comorbid gastric infection. It is advisable to actively treat the symptoms of anti-infective infusion**. A cephalosporin infusion may be used**.

Suggestions: It is recommended to pay attention to hygiene, pay attention to warmth, blood routine examination, chest X-ray examination, etc.

The source of tuberculosis infection is mainly the return of smear-positive tuberculosis excreted patients. With a source of infection, TB bacteria must also pass through a certain route before they can be transmitted to others. Tuberculosis patients mainly spread microfoams containing tuberculosis bacteria into the air through coughing or sneezing, and healthy people can be infected by tuberculosis bacteria by inhaling microfoams containing tuberculosis bacteria.

The degree of tuberculosis infection is mainly affected by factors such as the amount of bacteria excreted by tuberculosis patients, cough symptoms, and the closeness of contact. Children with TB in their parents, such as grandparents, are more susceptible to TB infection.

After a healthy person is infected with tuberculosis bacteria, tuberculosis does not necessarily occur, and whether tuberculosis occurs is mainly affected by two factors, that is, it is affected by the virulence of tuberculosis bacteria and the level of body resistance. After the human body is infected with tuberculosis bacteria for the first time, the vast majority of people usually do not have any symptoms, are not blind or hungry, and do not develop tuberculosis. But TB can occur at any time of the year when a small number of people infected with TB bacteria have reduced resistance.

The probability of developing tuberculosis is about 10%.

The first thing to do to prevent or reduce the occurrence of tuberculosis is not to be infected by tuberculosis bacteria, and tuberculosis will not occur without tuberculosis infection. Therefore, it is important to postpone the age of infection with TB bacteria. How do I know if I have a tuberculosis infection?

The tuberculin pure protein derivative (PPD) is mainly used for the first test, and the first reaction results are used to judge.

Analysis: Hello, it is considered to be a cough caused by mycoplasma infection, which is generally dry cough, proximal cough, long cough, and other symptoms are mild.

Guidance: Infection can be controlled with azithromycin or cephalosporins, antiviral oral solution can be prescribed, and nebulized inhalation** can also be carried out to humidify the respiratory tract and reduce the production of airway sputum.

Then take a blood test to check whether mycoplasma is infected, generally speaking, most viral infections are self-limited, and they will heal after a week, your symptoms are very similar to Mycoplasma pneumoniae infection, if the test is confirmed to be positive for mycoplasma, you can take three courses of oral azithromycin continuously, take it for four days and stop for three days for a course of treatment.

Inflammation of the upper respiratory tract, continue** until symptoms disappear.

Problem analysis: Hello: cough is not an independent disease, resulting in cough specific ** many classifications, generally common in the respiratory system **, accompanied by low-grade fever needs to be combined with blood routine and chest X-ray examination to diagnose whether there is a lung infection**.

Suggestions: The occurrence of the above clinical symptoms should focus on the respiratory infection, and it is recommended to perform routine blood and chest X-ray for differential diagnosis. Perform after the specific cough is identified**. Good luck soon**!
