There are more than two hundred different colds that physicians combine with a simple abbreviation.
Acute respiratory viral infections (ARIs) include a multitude of (about two hundred) diseases with a similar symptomatology. This includes influenza, parainfluenza, adenovirus infection, respiratory syncytial viral disease, rhinovirus infection, but for most of us it is just "flu" and "ARI".
Acute respiratory viral infections (ARIs) include a multitude of (about 200) diseases with similar symptoms. This includes influenza, parainfluenza, adenovirus infection, respiratory syncytial viral disease, rhinovirus infection, but for most of us it is just "flu" and "ARI".
"Respiratory" means only that the cold-causing virus enters the body through the respiratory tract and precipitates on the mucous membranes of the nose, mouth. Establishing an accurate diagnosis will help to find the most effective treatment regimen and predict the complications specific to each particular type of ARI.
The prefix of the couple… (from the Greek Para - next to, next to, the poster) means "located next to what is called in the second part of the word", hence the parainfluenza - a disease very similar to the flu. Indeed, parainfluenza is an acute viral respiratory disease that is transmitted by airborne droplets. It is characterized by inflammation of the larynx, which is manifested by sore throat and dry cough. In some cases, especially in patients with chronic diseases, the parainfluenza is complicated by bronchitis and inflammation of the lungs. The reservoir of infection is a sick person. Unlike the flu - a seasonal phenomenon, paragripp seasonality does not have and affecting predominantly children. Stable immunity does not leave paragrips.
Treatment of the disease is symptomatic, hospitalization is not required. When complications (pneumonia, otitis, sinusitis) are used antibiotics and sulfanilamide (ie antimicrobial) drugs. In case of the most dangerous complication - false cereal with symptoms of partial or complete narrowing of the lumen of the larynx (laryngospasm), which leads to difficulty passing air while breathing, shows hospitalization.
Adenovirus infection affects the mucous of the upper respiratory tract, eyes, lymphoid tissue, occurs with moderate intoxication. As regional lymph nodes are involved in the process, in the future, the viruses enter the bloodstream and can spread throughout the body, that is, develops viruses, through which the pathogen precipitates in various organs and systems.
The disease begins acutely, with chills or tingling, moderate headache, myalgia and arthralgia, in rare cases - with pains in the epigastrium. Characteristic nasal congestion, pain in the eyes, abundant tears - developing conjunctivitis. Adenovirus infection should be differentiated with the group of acute respiratory infections, pneumonia, tuberculosis.
Respiratory-syncytial viral disease
This acute respiratory disease mainly affects the lower respiratory tract with moderately severe intoxication. The disease develops gradually. Often, the inflammatory process begins with the mucous membrane of the nose and pharynx, followed by trachea, bronchi, bronchioles and lungs. In the development of pneumonia, besides the virus, it is important to attach bacterial infection.
Depending on the affected parts of the respiratory tract, distinguish between nasopharyngitis, bronchitis, bronchiolitis, and pneumonia. The duration of the disease in mild forms is from five to seven days, with severe forms of the disease - up to three weeks or more.
Rhinovirus infection is an acute anthroponosis (that is, the agent can parasitic in the natural environment only in the human body), a viral disease with selective lesion of the nasal mucosa. Rhinoviruses are widespread, in the temperate climate it is recorded throughout the year, more often in spring and autumn. The main symptom of rhinovirus infection is the abundant rhinorrhea (discharge from the nose) in the absence or weakness of intoxication. Rhinoviruses cause up to 25-40% of all acute respiratory infections. Epidemics are usually local. Ill people of all age groups, often several times a year. Most often, the disease is registered in children under 5 years of age.
The means of specific antiviral therapy of rhinovirus infections are absent, and treatment is symptomatic.
Any respiratory infectious diseases bring a headache (in all senses), fraught with complications, take away forces and interfere with the joy of life. Therefore, the best remedy is prophylaxis, for which, during periods of unsuccessful epidemiological conditions, it is necessary:
- Wash hands as often as possible
- Limit contact with sick people
- Avoid places of a large crowd of people
- Use public transport as little as possible.
