Influenza is caused by the influenza virus, so the use of antibiotics is often ineffective in treatment. Abuse of antibiotics can also cause infections of drug-resistant strains. In addition, the use of antibiotics may also cause certain side effects and worsen the condition. Therefore, in the early stages of contracting influenza, symptomatic treatment can be carried out according to routine therapy. If the high fever persists for several days, the cough worsens, and pus or blood sputum is produced, and the peripheral blood white blood cells are elevated during a hospital examination, it may be due to the concurrent infection of other bacteria or mycoplasma. In this case, antibiotics can be used under the guidance of a doctor.
There are several types of patients who can use antibiotics preventively: infants and young children, elderly and frail individuals, those with infectious underlying diseases or susceptible to infection factors, and patients who have been treated with immunosuppressive agents for a long time. But it is not easy to prevent the use of antibiotics for too long.
The pathogen of respiratory infections is often Gram positive cocci, while the pathogen of gastrointestinal and urinary tract infections is often Gram negative bacilli. So, when using antibiotics, different antibiotics should also be given to different pathogens.
