What are respiratory tract infections?
They are infections caused mainly by virus (90%) that can attack any part of your respiratory system.
Respiratory tract infections probably will happen during your whole life (in childhood they occur 6 to 12 times per year).
The most common infections are cold, flu, tonsillitis, sinusitis, pharyngitis and also otitis.
How is possible to know when there is a respiratory tract infection?
Usually there are sneezing, cough, lachrymation, fever, sickness, sore throat, and pain in the body. The initial symptoms are very similar regardless of the infection location and its cause - viral or bacterial - what can make diagnosis difficult.
Most times, diagnosis can be done by a doctor that will consider symptoms and signs the patient shows.
Sometimes, some tests may be necessary, but many of them will not present immediate results or they will not be instantly available.
These difficulties can lead to the use of antibiotics.
What are the main risks involved when using antibiotics?
Antibiotics are a great conquest of science and they allow treatment of infections that can put your health at great risk. However, we can observe that actually there is a tendency towards the excessive and precipitate use of antibiotics, many times due to the patient and his/her family insecurity when treating an infection.
So far we saw that many times respiratory tract infections are caused by virus. In this situation, the use of antibiotics is not helpful, since they can have several harmful consequences, such as:
• Adverse reactions
• Allergies
• Development of bacterial resistance
• Unnecessary increase of treatment costs
