How can we recognize respiratory infections?

• cough • sore throat • sneezing • headache • tired fatigue • sometimes occurs. Of the over 200 known viruses that can cause cold, rhinoviruses are the most common. In general, infections of the upper respiratory tract are divided according to the affected area. Respiratory viruses primarily affect the nose, throat (pharyngitis) and sinuses (). The main way of prevention is washing hands, possibly wearing a protective mask for a high degree of efficacy, eating fruits and vegetables. There is the possibility that the cold may sometimes evolve to a viral or bacterial origin.

Respiratory virosis normally starts with a feeling of tiredness and cold, sneezing, followed by the following days of nasal secretions and cough. Symptoms may occur within the first 16 hours of exposure, reaching the peak at 2-4 days of onset. They usually improve in 7-10 days, but in some cases they may persist for up to three weeks. Treatment has the role of relieving symptoms, but does not shorten or heal. Do not use antibiotics because they have no effect on viruses, and side effects are greater than the benefits.

Antibiotics are only used when bacterial superinfection is found. Treatments that help alleviate symptoms include simple analgesics and antipyretics, such as ibuprofen and paracetamol. In most cases, colds are mild and last for 3-7 days, although some people may continue to experience symptoms such as coughing, sneezing, up to 2 weeks. Some respiratory viruses can depress the immune system or damage the respiratory tract, facilitating the emergence of a new viral infection with another virus or bacterial infection, resulting in complications such as: • is the most common complication caused by the virus rule, much less of the superinfection . • Acute average otitis media: Medium ear inflammation.

• Lower respiratory tract infections: Acute bronchitis, pneumonia, exacerbations, bronchial hyperresponsiveness, convulsive cough. • Acute Bronchitis: Generated most commonly by respiratory syncytial virus, which affects children, the elderly and people with. • Pneumonia: fever, persistent cough, and typical changes in radiography. .
