Acute respiratory disease is understood as an acute respiratory disease. As a rule, this is a whole group of diseases caused by various microbial agents, including viral ones, which are characterized by damage to the upper respiratory tract. Since it is not always possible to identify the pathogen and there is no urgent need for this, such a diagnosis is as correct as possible, which is why it can also be made with influenza.
Influenza and acute respiratory infections start out the same. That is why during this period, even in the case of the beginning of the flu, the doctor diagnoses acute respiratory infections. A runny nose, sneezing appears, the temperature rises, chills begin. If after 2-3 days the condition does not improve, then most likely it is the flu, since acute respiratory infections are characterized by a rapid onset of the disease and an equally quick recovery. The body copes much faster with microbial agents than viral ones. The temperature with acute respiratory infections very rarely rises above 38 ° C and lasts no more than 1-2 days, after which a short period of weakness sets in and on the 5-7 day the condition is fully restored. A mild course of influenza is often confused with acute respiratory infections, since symptomatic therapy is sufficient for treatment - rest, warm, abundant drink, taking vitamins.
If acute respiratory infections during the first few days do not go away, and the temperature continues to rise, reaching 39-40 ° C, muscle pain and severe headaches join, then we are talking about the flu. These are characteristic symptoms that make it possible to do without laboratory diagnostics. It is used only in extreme and severe cases, when it is necessary to identify the type of virus. If the body is weakened, then with the flu, the temperature rises rapidly, within several hours, immediately reaching high values.
It is important to distinguish between acute respiratory infections and influenza, since the latter requires the mandatory intake of antipyretic drugs in order to alleviate the condition, and with acute respiratory infections, a temperature raised to 38 ° C only helps to cope with the infection. In general, despite the similarity of symptoms, acute respiratory infections, acute respiratory viral infections, influenza, adenovirus infection, parainfluenza, have characteristic features that allow doctors to identify the type of disease without additional laboratory diagnostics. The main and most important difference between acute respiratory infections and influenza is the absence of complications. A healthy person easily tolerates acute respiratory infections, while the flu is often complicated by otitis media, pneumonia, neuritis and other infectious diseases. If you have been vaccinated against the influenza virus and symptoms of a cold have appeared, then most likely it is not the flu, but ARI or ARVI, since the vaccination is quite effective and reliably protects even during an epidemic.
At the first manifestations of any respiratory disease, you need to call a doctor at home or an ambulance, especially if the disease begins in children, weak people and people of mature age. It is recommended to exclude contact with healthy family members, which will reduce the likelihood of spreading the infection.
