Prevention of H1N1 influenza is primarily achieved by enhancing individual immunity and implementing effective protective measures, rather than relying on medications. However, in some cases, doctors may recommend the use of antiviral drugs for prevention, especially for high-risk individuals.

Influenza A is an acute respiratory infectious disease caused by the influenza A virus, and it is highly contagious. Receiving the influenza vaccine is one of the most effective methods to prevent Influenza A. The influenza vaccine can stimulate the human immune system to produce antibodies against the influenza A virus, thereby reducing the risk of infection.

It is recommended to receive the annual influenza vaccine each year to address the constantly evolving viral threats. Baloxavir marboxil is a new antiviral medication that exerts its effects by inhibiting the synthesis of influenza viral nucleic acid. For the prevention of Influenza A, baloxavir marboxil can be considered as a preventive medication option for specific populations, such as those at high risk of influenza complications.

Lianhua Qingwen capsules contain ingredients such as forsythia and honeysuckle, and have the functions of clearing heat and detoxifying, and ventilating the lungs to relieve heat. During an Influenza A outbreak, healthy individuals taking Lianhua Qingwen capsules may help enhance the body's antiviral capabilities and alleviate symptoms after infection.

Prevention of H1N1 influenza also requires attention to personal hygiene, such as frequent hand washing, maintaining indoor ventilation, and avoiding visits to crowded places.
