Avian influenza is an infectious disease caused by the avian influenza virus, primarily affecting poultry but also capable of transmitting to humans. The main goals of treatment are to alleviate symptoms, accelerate recovery, and prevent disease progression.
Treatment typically includes antiviral medications, supportive therapy, and symptom management. Early intervention is crucial for improving prognosis.
The primary treatment options include antiviral drugs such as Oseltamivir and Zanamivir. These medications inhibit viral replication, reducing viral load.
Supportive therapy involves rest, hydration, and nutritional support to help the body fight the virus.
These drugs target the viral neuraminidase, preventing the release of new viral particles from infected cells, thereby reducing the spread of the virus within the body.
Treatment for avian influenza is indicated for patients with confirmed or suspected infection with the avian influenza virus, especially those whose symptoms have appeared within 48 hours.
High-risk groups such as pregnant women, young children, the elderly, and immunocompromised individuals should start treatment as early as possible.
Oseltamivir is usually administered orally, with a dose of 75 mg twice daily for adults and children, for a duration of 5 days.
Zanamivir requires inhalation, with a dose of 10 mg twice daily for adults and children, for 5 days.
Antiviral drugs can effectively reduce the severity of symptoms, shorten the course of illness, and lower the risk of complications.
Common side effects include nausea, headache, and diarrhea, which are usually mild and temporary.
Contraindicated in individuals allergic to the medication. Pregnant and breastfeeding women should use under medical supervision.
Dose adjustments are necessary for children and patients with renal impairment.
Antiviral medications may interact with other drugs such as probenecid. Patients should inform their healthcare provider of all medications they are taking.
Clinical trials have demonstrated that early use of antiviral drugs can significantly improve outcomes, reduce hospitalization rates, and decrease mortality.
If allergic to primary antiviral drugs, other options such as Peramivir can be considered.
The duration of treatment depends on the severity of the illness. Generally, mild cases recover gradually after 7 to 10 days of antiviral therapy, while severe cases may require longer hospitalization and supportive therapies such as mechanical ventilation.
What dietary precautions should patients take during treatment?Patients should focus on light, easily digestible foods, and increase intake of vitamin C and protein-rich foods such as fruits, vegetables, and lean meats to boost immunity. Avoid spicy, greasy, and high-sugar foods to prevent worsening symptoms.
What follow-up examinations are recommended after treatment?Patients should have regular follow-up visits, including lung function tests and blood work to assess recovery. Imaging studies may also be recommended to ensure there is no ongoing lung damage or infection.
What precautions should be taken when using antiviral drugs for avian influenza?Antiviral drugs like Oseltamivir and Zanamivir should be started within 48 hours of symptom onset to ensure efficacy. Patients must adhere strictly to prescribed dosages and avoid self-adjusting or discontinuing medication to prevent drug resistance and relapse.
How can patients prevent reinfection after recovering from avian influenza?Post-recovery, patients should maintain good hygiene practices such as frequent handwashing, avoiding contact with poultry and contaminated foods. Vaccination against seasonal influenza is also recommended to reduce the risk of other flu infections.
