Types of diseases: ARVI, flu, colds
Autumn, winter and spring are the times when you most often catch a cold. It should be noted that there is no diagnosis of a cold. This collective concept most often includes infectious viral diseases that have identical symptoms and affect the upper respiratory tract. Official medicine calls such diseases ARVI (acute respiratory viral infections).
The causative agents of such diseases are pneumotropic viruses, of which there are more than 300 species (including adenoviruses, rhinoviruses, reoviruses and others).
ARVI symptoms:
- sneezing;
- runny nose;
- cough;
- pain in the head, eyes and throat;
- state of weakness.
Another seasonal disease of viral etiology is influenza. Today, there are about 2000 different variants of the influenza virus, differing in their antigenic spectrum. This disease can cause symptoms similar to ARVI, but the pathogen penetrates the blood faster. As a result, with influenza, muscle pain and fever may develop within the first day after infection.
For preventive therapy and treatment of infectious viral lesions, immunostimulants and antiviral drugs are used.
How do antiviral drugs affect the immune system?
Immunomodulators are a widely used antiviral drug for colds. They fight infection by stimulating the human immune system. The drugs do not invade cells, but cause their own interferons to act. Their use causes activation (a surge) of one’s own immunity, which helps fight infection.
But such medications should be taken with caution by those who have hereditary autoimmune diseases (only as prescribed by a doctor). But for children and people at high risk of such diseases, it is better to avoid them.
When antiviral drugs do not work as expected
Although most modern drugs have a broad spectrum of action, drugs against viruses usually cannot affect bacteria. This means that for bacterial sore throat, bronchitis and pneumonia, antiviral drugs will not have the desired effect.
However, in some cases, antiviral drugs (both expensive and budget) may be useless in the fight against viruses that are resistant (immune) to this drug. Moreover, these can be either strains that are immune in principle to the active substance, or in a specific case (they do not affect a specific person).
How do immunomodulators and antivirals work?
Immunomodulators are substances that affect the immune system. They are used for the nonspecific treatment of infections caused by viruses. The principle of action of such drugs is based on regulating the functioning of the immune system by activating immunocompetent cells. Immunomodulators for acute respiratory viral infections increase your own immunity, which helps the body cope with the infection and prevent possible complications.
Medicines that act directly on the virus itself and the mechanism of its replication (reproduction) are called antiviral. By introducing themselves into the structure of the virus, such substances disrupt cellular metabolic processes from the inside and lead to the death of viral cells.
When should you use an antiviral drug for influenza and acute respiratory viral infections, and do doctors recommend this?
Many people, under the influence of certain media, are sure that there is no point in taking medications for ARVI. After all, as the old proverb says, a cold goes away in a week without treatment, and in seven days with treatment. This means that this disease can be survived without medication. However, unfortunately, statistics speak of disappointing facts. According to the World Health Organization, up to 650 thousand people die annually from respiratory diseases associated with seasonal influenza infection.v Not everyone knows that influenza infection and colds can negatively affect the heart. This reduces the average life expectancy by several years.vi After a severe course of ARVI, serious damage to the respiratory system, including pneumonia, is often diagnosed. Also, after acute respiratory viral infections, diseases of the blood vessels and the central nervous system are often detected.
Therefore, the main argument in favor of taking anti-viral medications is the need to reduce the high risks that accompany influenza infection. The second reason is due to the fact that timely and adequate treatment shortens the duration of the disease and weakens its symptoms. If you take a good flu antiviral when you develop symptoms of influenza infection and colds, you may experience a shorter period of runny nose, headaches, and fever.
Pros and cons of antivirals
The use of antiviral drugs, like any treatment, has its positive and negative sides. Numerous clinical trials confirm the effective effects of such drugs for the treatment of viral diseases. But the lack of timely treatment for infections can lead to complications. That is why it is very important to start treatment on time to fight colds and flu.
Before seasonal epidemics of colds and flu, doctors recommend procedures to boost immunity and timely vaccination.
Like any medicine, antiviral drugs may have contraindications, which is a significant disadvantage for therapy. However, the correct selection of the remedy will avoid side symptoms and speed up recovery.
ANTIVIRAL DRUGS FOR COLDS: SYSTEM REQUIREMENTS
So, you or your child feel that ARVI or influenza is already “knocking on the door”, and the symptoms of the disease are increasingly “taking hold”: a sore throat, an “itch” in the nose, a fever, a body ache and a headache. .
Of course, the main property that proper treatment should have is its antiviral nature. If the source of the disease is viruses, then treatment aimed primarily at eliminating the cause of the disease will be effective.
Of course, effective treatment is treatment that will help cope with the symptoms of the disease, because it is they that cause the main “life inconveniences”.
Another necessary attribute of effective treatment: it must certainly have a positive effect on the body’s own immunity.
And the argument, although not entirely medical, is important in our time: it is extremely desirable that the treatment be inexpensive.
Can I run to the pharmacy? In no case!
The first and only correct action for symptoms of ARVI and influenza is to consult a doctor. Only a doctor can establish the correct diagnosis, and for this, in addition to examining the patient, he may require additional tests. And only after this the doctor decides which treatment will be effective in this particular case.
Perhaps the doctor will recommend Ergoferon as a treatment. This modern antiviral drug is designed specifically to combat various types of ARVI and influenza viruses. At the same time, the drug can help relieve inflammation, weaken all the main symptoms of a cold and strengthen the body's immunity.
When treating colds in children, the drug is approved for use from the age of 6 months. And during periods of a “seasonal surge” of colds, it can be taken as a means of prevention.

PREVENTION OF ARVI AND FLU: EFFECTIVE REMEDIES. AND INEXPENSIVE!
Yes, finding an effective antiviral drug for colds is important. But perhaps even more important is to make sure that you have to look for it as little as possible. But the means to protect yourself and your loved ones from colds are literally “within walking distance”!
Fresh air product. Take it daily, come to the appointment dressed appropriately for the weather. It is best taken in combination with properly selected physical activity.
“full sleep” remedy. A chronically sleep-deprived, overtired child is a “target” for ARVI and influenza.
Means “proper, varied nutrition.” Supplies the immune system with essential vitamins and microelements.
Hardening procedures: a contrast shower not only has a tonic effect, but also properly “trains” the internal thermoregulation system.
Occupational and rest hygiene: regular ventilation of premises, wet cleaning.
And one more remedy, completely inexpensive and, at the same time, extremely effective - just a good mood. Take it in the treatment of ARVI and influenza, and, of course, as a means of preventing them!
How to choose a drug
In order to correctly choose effective drugs whose antiviral properties will help cure influenza or ARVI, you need to accurately diagnose the disease. After this, you should make sure that there are no contraindications for using the product. It is also important to remember that different medications are used at different stages of a cold.
Take special care when choosing antiviral drugs and then you can help your body overcome a cold in the shortest possible time.

Antiviral drugs for influenza: main mechanisms of action
By introducing themselves into the cells of the respiratory tract, viruses cause damage to structures that perform barrier functions. Antiviral for flu and colds blocks some stages of viral infection:
- At the stage of infection and penetration into the cell, the drug blocks viral activity. The medicine can slow down or prevent the process of bringing viral particles closer to the cell membrane.
- At the second stage, if the virus does become close to the cell, the viral genome is copied. By using anti-viral drugs, the replication of viral DNA and RNA is blocked.
- During the synthesis of viral proteins and at all stages of virus assembly, various drugs are used: interferon-based, protease inhibitors and structural protein inhibitors.
- When the virus comes out and tries to invade other cells, it can be defeated with drugs based on neuraminidase inhibitors and antibodies.
The incubation period of the influenza virus in the body is on average three days. In order to choose the right treatment and antiviral for influenza and ARVI with minimal side effects, it is important not to confuse these diseases.iv
