Can a cold caused by a virus cause a fever, what to do if you have a viral flu fever

Viral or bacterial colds can also cause fever,,, I had a fever and slight body aches, but there were no other symptoms. ”

Don't use your own medicine,,, your situation is not necessarily a cold, because you have no other cold symptoms, it is recommended that you go to the local regular hospital to find out**, and then use antipyretics and **disease medicine,,, it is strongly recommended that you go to the local regular hospital to find out**, and then use antipyretics and **disease medicine, fever, slight body aches", because these are symptoms because of fever. These can only mean that you have a fever, and you can't see the real ** of your current fever, so you can't diagnose the drug, it is strongly recommended that you go to the local regular hospital to find out**, and then use antipyretic drugs and **disease medicine,

Yes. And the doctor will prescribe a list of saline. It is best to go to the hospital for diagnosis and follow the doctor's advice. Blindly taking medicine by yourself is not only not easy to get better, but also easy to delay the condition.

The cold is also an acute infectious rhinitis, commonly known as the "cold". It is caused by respiratory viruses, of which coronaviruses and rhinoviruses are the main pathogenic viruses. The virus is excreted and spread from respiratory secretions, and infection is easily induced when the body's immunity is weakened, such as cold, malnutrition, excessive fatigue, excessive smoking and alcohol, systemic diseases and chronic diseases of the nose itself affect the smooth flow of the respiratory tract.

Bacterial infections secondary to a cold attack. At the beginning of the cold, there is a feeling of dryness and itching, sneezing, general malaise or low-grade fever in the nose, and then gradually nasal congestion, loss of sense of smell, a large amount of clear nasal discharge, nasal mucosal congestion, edema, and a large amount of watery or purulent discharge. In the absence of complications, the course of the disease is about 7-10 days.

Because the virus lives in the cells of the human body, there is no medicine in the world that can directly kill the cold virus, and the effective way is to rely on the human immune system. Therefore, colds should be mainly supported, with special attention to rest, drinking plenty of water, and eating lightly. This gives the immune system adequate physical support.

A cold can trigger a bacterial infection, but you should never use medication**. After the body's immune system kills the virus, most infections heal automatically. Blind medications** can increase bacterial resistance and prevent the body's immune system from functioning properly.

Is the phlegm yellow? Cough or not? If you have yellow phlegm and cough, it is recommended to take some double coptis, then you go to the hospital to check it, take a chest X-ray, and do a blood test.

Fever and cold are a minor illness that often occurs in life. Many patients are bothered by its symptoms. Because the degree of impact of fever and cold on the body is relatively obvious.

In addition, some patients who have no experience in prevention will be in a hurry, so many people want to know what to do if they have a viral fever and cold?

The first thing to do when you have symptoms of a viral fever and cold is to go to the hospital for a check-up. In addition, you should also pay more attention to all aspects of your life and do not go to more dense public places. In addition, it is necessary to keep indoor air circulation, which can easily aggravate the condition if the air is not well circulated.

If you have a viral fever or cold, you can use medicine, and if necessary, you can go to the hospital for an intravenous drip. Patients should consult their doctor when taking medication and do not blindly take it by themselves.

What are the symptoms of a viral fever cold.

Viral fevers and colds usually develop very quickly. And the disease tends to last longer than a common fever and cold. In addition, the drugs used for viral fever and cold are significantly different from ordinary ones.

Therefore, when you find that you have a viral fever and cold, then you must go to the hospital for examination. Don't blindly use drugs by yourself**, there have been serious consequences in the past.

No matter what the disease, as long as you have a cold and feel unwell, you should go to the hospital as soon as possible**. Don't take chances, thinking that you can get over with one shoulder. In normal times, we should pay attention to a good living habits, so that we can avoid the invasion of many diseases.

It is best to exercise properly and eat plenty of fresh vegetables and fruits.

Generally we know that if we are infected with the virus, we will have a fever later. The main reason is that the virus will invade our body in the future. At this time, some of our body's immune cells will attack it.

If such a tool is used, a part of the immune cells will lose their lives during the attack, and if this inflammation occurs, it will cause a certain fever. In addition, if our body has a self-defense ability, it will put our body in a state of fever and fever.

After the arrival of the new crown epidemic, "temperature measurement" is an easy way for many people to initially determine whether they are infected with the virus, because fever is a key symptom of various infections.

Most people probably attribute this change to the immune system, thinking that a feeling of fever, chills, or malaise means that the immune system automatically turned on its defenses.

This is not the case, and behind all this is the brain's command. More specifically, the nervous system is constantly "docking" with the immune system, and when it confirms that the body is infected, it coordinates a series of behavioral and physiological changes, including the appearance of symptoms that are not very comfortable with us.

In a study published this week in the top academic journal Nature**, scientists found a special group of brain cells for the first time through experiments on mice: a handful of nerve cells that manipulate a series of symptoms such as fever, chills, and loss of appetite after sensing changes in immune status due to infection.

Professor Catherine Dulac of Harvard University is the corresponding author, and Professor Zhuang Xiaowei, a well-known Chinese scientist, also participated in the study.

This special group of neurons is located in the hypothalamus, a key brain region "famous" for regulating important functions such as body temperature, eating, drinking, and endocrine activity. The researchers first managed to get the lab mice with a fever due to a bacterial infection, then searched their brains for nerve cells that were activated at this time, and finally noticed neurons located in the ventromedial preoptic region (VMPO) of the hypothalamus.

To confirm the function of these cells, the researchers used chemogenetics and optogenetics to precisely control the population of about 1,000 neurons, manipulating them to transmit signals. It was found that VMPO neurons are essential for producing symptoms such as fever. Activating these cells led to increased body temperatures, chills, and decreased appetite – a set of symptoms that are very similar to those that often occur in humans after infection.

In addition, the researchers confirmed that this group of nerve cells projects into 12 brain regions, including some brain regions known to control thirst, pain sensitivity and social interaction, in other words, some other symptoms that are common after infection may also be influenced by this group of nerve cells.

In this article, the researchers go a step further to reveal how these nerve cells sense the body's immune status. They found that these nerve cells had an excellent geographical location: right next to the blood-brain barrier.

The blood-brain barrier separates the brain from circulating blood, meaning that this is where the brain and immune system communicate with each other.

The researchers pointed out that the cells that make up the blood-brain barrier can release immune signals, and the neighboring hypothalamic VMPO neurons are equipped with some receptors to receive immune signals, so the cells of the blood-brain barrier trigger nerve cells that control symptoms such as fever through a mechanism called "paracrine signaling".

It's your immune system fighting the virus.

Viral infection fever is not unprovoked, so what causes viral infection fever?

Viral infection fever is a fever symptom caused by the body's immune system resisting viral infection, and a variety of viral infections can cause fever symptoms, such as varicella-zoster virus, influenza virus, measles virus, mumps virus, etc. Fever in viral infection is caused by the action of a pyrogen, which causes the adjustment point of the thermoregulatory center to move upward, causing the regulation of body temperature to rise, resulting in the appearance of fever symptoms. Moderate heat in the human body can increase the production of antibodies, promote lymphocyte turnover, improve the chemotaxis and phagocytic ability of granulocytes, and a certain high temperature can extinguish microorganisms that are sensitive to heat, but too high temperature will cause rapid consumption and body damage.

It is important to know that if there is no concurrent bacterial infection, the course of the disease is about 7-10 days. Drink plenty of water and rest more, and you can heal yourself. Taking anti-cold medicines and symptomatic medications can shorten the duration of the disease and reduce symptoms such as fever, headache, nasal congestion, runny nose, and body aches.

Viral infections can be transmitted to others, so is a viral infection fever contagious?

Viral fever refers to the febrile reaction of the human body due to viral infection, viral infection depends on the specific situation, in fact, the vast majority of infectious diseases are caused by viral infection, most viral infections may lead to transmission, especially respiratory tract infectious diseases, such as the often said flu, influenza A, influenza B, or now more adenovirus infections are caused by viral infections in the respiratory tract, this disease is transmitted through the respiratory tract, which is more likely to lead to infection More careful.

Other viral infections may also cause fever, such as acute HIV infection or acute hepatitis A infection, acute hepatitis B virus infection and other conditions may cause fever, the above diseases are blood-borne diseases, not through the respiratory tract or contact transmission, mainly through blood-borne contact, because the blood and body fluids contain a large number of viral pathogens, for such patients after infection if contact with their blood and body fluids will also lead to transmission.

Both influenza and viruses can cause respiratory infections, and the symptoms are similar. However, there are some differences between the flu and contracting a virus.

First, the flu is more likely to cause severe symptoms. Influenza viruses can cause severe damage to the respiratory system and may even lead to respiratory failure, so influenza viruses usually cause more severe symptoms. Ordinary viruses usually do not cause such severe symptoms.

Second, influenza viruses are more contagious. Influenza viruses are more easily transmitted through the air than ordinary infectious viruses, so the flu spreads more easily among people.

Finally, influenza viruses are more likely to cause epidemics. Influenza viruses can spread rapidly through the population, leading to flu epidemics. It is not so easy to get infected with ordinary viruses.

Cause an epidemic. In short, if you do not do antigens, you can start from the severity of symptoms, infectiousness and epidemic to distinguish between influenza and infected viruses.

However, if you want to accurately distinguish between the flu and the virus, it is best to determine it through testing. Tests can be done by testing samples such as blood, nasal discharge, saliva, or throat swabs to determine the type of virus.
