Atypical flu. What is the danger of an asymptomatic course and how to recognize it?

Influenza - stands alone in the families of ARVI. Despite the fact that this infection is viral and respiratory, it is quite noticeably different from those pathogens that lead to the development of standard colds. Indeed, in terms of its consequences and complications, it is more formidable.

Influenza usually proceeds quite hard, delivers a lot of unpleasant minutes and sensations to a person, it happens that it is delayed. Moreover, as noted by doctors, there are also atypical forms of such a disease.

“Atypical flu is usually understood as having several options. One of them is asymptomatic, that is, when there is a carrier, but there are no manifestations. This poses a danger to others. There is also an akatarral option, when any symptoms are noted, except for those that everyone expects according to the standard scheme, that is, not respiratory. There may also be a lightning-fast option, ”says therapist, endocrinologist, cardiologist Tatyana Romanenko.

The classic flu, and as Tatyana Romanenko notes, there is no concept of “atypical” in the official medical classification, it is characterized by headache, high fever, and joint pain. The same thing that is meant by atypical, often completely different diseases. “This is often the name for other infections that cause disorders of the gastrointestinal tract system - diarrhea, vomiting, etc. That is, for the most part, we mean rotavirus, noravirus, ”the therapist notes. But there are still options when the flu flows like the flu, but without a fever. Then the rest of the symptoms for a person are somewhat leveled and become less serious, even at a subconscious level.

Determining the atypical form of influenza, as well as with any other non-standard pathologies, is, in particular, quite difficult because of this. By the way, the absence of elevated body temperature is called one of the main signs in the atypical course of the flu. Accordingly, many may perceive symptoms such as weakness and muscle aches as normal overwork, continue to go to work and, accordingly, infect others. People also put themselves in danger in such a situation, since it is impossible to endure such a formidable disease on their feet.

Disease therapy

Despite the fact that the course of the flu may be slightly atypical, it is worth contacting a doctor at the first sign of illness. After all, the treatment of influenza, even with non-standard symptoms in the early stages, is more effective. For example, if this is the so-called intestinal flu, then it is important to have time to prevent dehydration. If it is a flu without fever, it is necessary to quickly deal with the pathogen in order to exclude complications and the addition of a secondary infection.

The treatment itself for the treatment of an atypical course of the disease will be according to the situation. With a blurred clinical picture of classic influenza, we will talk about therapy as in the usual course of the disease. If we are talking about disorders affecting the gastrointestinal tract, then the doctor will prescribe a separate treatment.


It is important to understand that any flu - be it classic or atypical - can be fraught with serious complications. “If the classic flu drags on in its course, then such a complication as viral pneumonia can occur, it is already atypical. Also, against the background of a weakened immunity, bacterial flora can join, and this is already such a complication as atypical viral-bacterial pneumonia. In general, the relationship between influenza and respiratory pathologies is a classic, ”says Tatiana Romanenko.

By the way, as the specialist notes, it is atypical pneumonia that should be given special attention. After all, pneumonia is the most common complication of the flu. And if a viral pathology proceeds, for example, without fever, a person continues to carry it on his feet, he risks even more prolonging the course of the disease and leading to such a terrible complication.

The share of SARS accounts for a small number of the total statistics of pneumonia, but this does not make them less formidable. The classic influenza complication is characterized by high fever, cough, shortness of breath, the presence of purulent sputum and changes in blood counts towards an increase in leukocytes. “This is not the case with SARS. First, the current is not typical, it is erased. The temperature may not be high, the cough is not pronounced, there may be no changes in the blood tests. Most often, changes are detected only on CT. The situation is aggravated by the fact that there is no specific therapy for SARS, ”notes Tatyana Romanenko.

In order to prevent the situation when the disease becomes too difficult, and in order to recover, you will have to spend much more time, effort and money, you should be attentive to yourself.

And in a dangerous period of time for ARVI, do not ignore any ailments in the body.


It is worth taking care of prevention so as not to pick up either the classic flu or the atypical one. The advice is pretty standard - strengthening the immune system, getting healthy sleep, proper nutrition, moderate exercise, walking in the fresh air, and personal hygiene. Also, doctors say, it is worth taking care of prevention in the form of getting a flu vaccine. They take into account all current strains and are able to protect against infection with high efficiency.

There are contraindications, it is necessary to consult a doctor
