If a girl has a fever, it is recommended to improve the examination to see what causes the fever, such as upper respiratory tract infections, lung infections or infections caused by the digestive system, urinary system or pelvic cavity of the uterus, etc. The drugs used for different infections are different. The more common upper respiratory tract infections are considered to be bacterial or viral, mixed infections, which can be clarified based on routine blood and related test indicators. If the routine blood results suggest bacterial infection, you can add antibiotics for treatment, such as the cephalosporin antibiotic cefixime tablets, and you can add antiviral drugs, such as oseltamivir or ribavirin, when the routine blood suggests viral infection.
