Flu or influenza is a viral infection that attacks the nose, throat, and lungs . Flu sufferers can experience fever, headache, runny nose, stuffy nose, and cough.
Many people think the flu is the same as the common cold . Although the symptoms are similar, the two conditions are caused by different types of viruses. Flu symptoms are more severe and attack suddenly, while the symptoms of the common cold tend to be mild and appear gradually.
Flu is a disease that is easily transmitted to other people, especially in the first 3-4 days after the patient is infected. In some cases, people with the flu can transmit the disease before symptoms appear.
Causes and Symptoms of the Flu
A person can catch the flu if he accidentally inhales the droplets of saliva in the air, which the sufferer expels when sneezing or coughing. In addition, touching the mouth or nose after handling objects that have been splashed by the patient's saliva can also be a means of transmitting the flu virus.
Symptoms of the flu include fever, runny nose, stuffy nose, and headache. Although the symptoms are the same as the common cold, flu symptoms are more severe and often strike suddenly.
Immediately see a doctor if the above symptoms do not improve after two weeks, or improve but then worsen. Emergency measures need to be taken if flu symptoms are accompanied by shortness of breath or loss of consciousness .
Flu Treatment and Prevention
Mild flu can be overcome by getting plenty of rest, eating healthy foods that contain vitamin C , and drinking lots of water. However, if the symptoms are severe, immediately go to the doctor to be given medication to speed up recovery and prevent complications.
The most effective way to prevent flu is to undergo influenza vaccination . In addition, you are also advised to diligently wash your hands and stay away from people with flu.
A cold that resolves and then recurs and worsens can be a sign of serious complications, such as pneumonia, heart problems, meningitis , or a viral infection of the brain. These complications can be more risky for pregnant women and people who have weak immune systems.
