The most harmless version of ARVI. The incubation period lasts an average of 3 days. Body temperature does not exceed subfebrile values (but, as a rule, does not increase at all, since the body does not undergo general intoxication). The disease manifests itself in the form of abundant serous and mucous discharge from the nose, sneezing and itching in the nasopharynx, nasal congestion. Sometimes there are symptoms such as tearing, irritation of the skin around the nostrils (due to the constant flow of mucus and skin contact with handkerchiefs, etc.), dry cough. Rhinovirus infection usually does not result in any serious complications.
MS (respiratory syncytial infection)
Also applies to mild diseases. The incubation period for MS can last from 2 to 7 days. Symptoms usually include subfebrile body temperature, sneezing, and nasal mucus discharge, tickling and coughing, sometimes a mild pain in the larynx. MS takes place within 10–12 days, but in some cases, this type of ARVI (particularly in older people) can be transformed into a chronic and prolonged form.
The incubation period of this type of ARVI lasts up to 10 days, then the symptoms appear sharply – the temperature rises to 38–39 0 С, and at first it goes up steadily, and then, after 5–6 days, decreases (however, the next wave of fever may occur ). In addition to the high temperature, patients complain of conjunctivitis, developing first on one eye, and after 2-3 days, exciting mucous membranes of the second. In addition, nasal congestion and serous-mucous discharge, swelling of lymph nodes in the neck, cough with sputum discharge, tingling, and dry throat, sometimes painful swallowing, hoarseness are observed. Sometimes, a patient might experience an increase in the size of the spleen and liver (revealed through a medical examination).
The most severe and dangerous infection from the group of acute respiratory viral infections. Its incubation period is from several hours to several days. The onset is acute and sudden: due to the intoxication of the body, the temperature rapidly rises to febrile values. Its symptoms include chills, aching joints, general weakness, dizziness, and headaches; in severe cases, the onset of the disease may be accompanied by symptoms of meningitis, nausea and vomiting. Then there are signs of lesions of the mucous membranes of the nose and throat: tickling and irritation in the throat, dry cough, slight discharge from the nose, sneezing, in some cases, nosebleeds are possible. A medical examination may also reveal tachycardia and muffled heart sounds. Improvement of the patient’s condition begins 3-4 days after the onset of the first symptoms: body temperature drops to normal, signs of viral intoxication become less noticeable. The flu may usually last for at least a week (sometimes up to two weeks).
The parainfluenza is similar in its manifestations to the flu, but its symptoms are more blurred, the incubation period is usually longer (2-7 days), serious complications are less likely. Symptoms include a jump in body temperature to febrile values, signs of intoxication, catarrhal symptoms – runny nose, tickling, and dry throat, severe pain, hoarse voice, etc. The patient’s condition may worsen for 3-4 days, after which a change in the course of the disease occurs, and the patient gradually recovers. A full recovery from parainfluenza may take an average of 7–10 days.
