Chrípka

Chrípka, commonly known as influenza, is a contagious respiratory illness caused by influenza viruses. These viruses infect the nose, throat, and sometimes the lungs. While many symptoms overlap with the common cold, the flu typically comes on more suddenly and is more severe.

Symptoms of influenza can include fever, chills, muscle aches, cough, sore throat, runny or stuffy nose, headaches, and fatigue. Some people, particularly children, may experience vomiting and diarrhea. Most people recover within a few days to less than two weeks, but some individuals can develop complications, such as pneumonia, bronchitis, sinus infections, and ear infections. Influenza can also worsen chronic health problems like asthma or heart disease.

Influenza viruses spread mainly by droplets made when people with the flu cough, sneeze, or talk. Less often, a person might get influenza by touching a surface or object that has the virus on it and then touching their own mouth, nose, or eyes.

Prevention is key. The most effective way to prevent influenza is by getting vaccinated annually. Good hygiene practices, such as frequent handwashing with soap and water, covering coughs and sneezes, and avoiding close contact with sick people, also help reduce the spread. Antiviral drugs can be used to treat influenza, but they are most effective when started within 48 hours of symptom onset. They can reduce the severity of illness and prevent complications.
