Hengitystärveläisten

Hengitystärveläisten, or respiratory tract infections, are illnesses that affect the breathing passages, including the nose, throat, lungs, and airways. They are typically caused by viruses, though bacteria can also be responsible. Common examples of respiratory tract infections include the common cold, influenza (flu), bronchitis, pneumonia, and sinusitis.

Symptoms can vary widely depending on the specific infection and its severity, but often include coughing, sneezing, sore throat, runny or stuffy nose, fever, and general malaise. More severe infections like pneumonia can lead to difficulty breathing and chest pain.

Transmission of respiratory tract infections usually occurs through airborne droplets produced when an infected person coughs, sneezes, or talks. These droplets can be inhaled by others or land on surfaces, which can then be touched and transferred to the eyes, nose, or mouth. Good hygiene practices, such as frequent handwashing, covering coughs and sneezes, and avoiding close contact with sick individuals, are crucial for preventing their spread.

Treatment for respiratory tract infections generally focuses on managing symptoms, as many viral infections resolve on their own. Rest, fluids, and over-the-counter medications for fever and pain relief are common recommendations. Antibiotics are only effective against bacterial infections and are not used for viral illnesses. In cases of severe infections or for individuals with underlying health conditions, medical attention is necessary to prevent complications.
