Patients at high risk for influenza: children less than 2 years of age; elderly people 65 years or older; people with chronic diseases such as bronchial asthma, cardiovascular disease (excluding simple hypertension), renal, hepatic’ hematologic, metabolic (including diabetes), or neurologic and neurodevelopmental disorders; immunosuppressive diseases (medications or HIV); pregnant women or within 2 weeks of giving birth; people less than 19 years of age, long-term use of aspirin; people who are excessively obese; people living in institutions such as nursing homes. In other words, we usually have colds, including influenza, there are no specific medications, just rest and symptomatic treatment (such as antipyretics, painkillers – components of cold medicines), and should not use drugs indiscriminately. However, when influenza is suspected and by the above risk factors, more attention is paid and early (within 48 hours preferably) oral antiviral drugs, such as, Tamiflu (oseltamivir), etc. are taken. Patients who are not at high risk as mentioned above can also be considered for application, especially within 48 hours of onset, which should be more serious and patients can consider antiviral therapy if they are willing to accept it. So, you can’t take a cold lightly, but you can’t have a cold and use drugs indiscriminately!
