Introduction

Influenza B refers to type B influenza. Generally, the choice between Arbidol and Oseltamivir for treating influenza B depends on the patient's age. Arbidol is suitable for adults aged 18 to 65 years, while Oseltamivir can be used in adults and children aged 1 year and older. It is recommended to select the medication under a doctor's guidance to ensure safe and effective treatment.

　　Influenza B refers to type B influenza. Arbidol is a broad-spectrum antiviral medication available in various formulations including tablets and capsules. Oseltamivir, on the other hand, is a neuraminidase inhibitor available in multiple formulations such as granules and capsules. Generally speaking, the choice between arbidol and oseltamivir for treating type B influenza depends on the patient's age. Arbidol is suitable for adults aged 18 to 65 years, while oseltamivir is suitable for both adults and children aged 1 year and older. It is recommended to choose the medication under a doctor's guidance. A detailed explanation is as follows:

　　

　　Arbidol primarily works by blocking the fusion of the viral lipid membrane with the host cell membrane, thereby effectively inhibiting the virus from entering the cell for replication. This mechanism interrupts the viral transmission chain at its source, reducing viral replication within the body, ultimately achieving therapeutic effects against type B influenza. It is generally suitable for adults aged 18 to 65 years.

　　Oseltamivir is primarily used to treat influenza caused by influenza A and B viruses. If a patient is diagnosed with type B influenza and begins treatment within 48 hours of symptom onset, oseltamivir can effectively alleviate symptoms and shorten the duration of illness. Oseltamivir has a broad age range of applicability and is suitable for treating both adults and children aged 1 year and older with influenza A or B.

　　During flu season, it is recommended to take preventive measures such as receiving a flu vaccine and maintaining good personal hygiene habits to reduce the risk of infection.

If no intact tablets are found in the vomit, and vomiting is mild (only one episode without persistent nausea), and the medication was taken to treat influenza (especially within 48 hours of symptom onset), the drug may have been partially absorbed but insufficiently.

Can avian influenza be transmitted to humans?

Under normal circumstances, avian influenza can be transmitted to humans, but the probability is low. Its transmissibility is closely related to factors such as transmission routes, viral mutations, and human exposure risks.
