大流行性流感的威胁一直存在。当一种以前没有影响过人类的新型流感病毒出现、传播并导致人类疾病时，大流行可能会发生。

 流感病毒是不可预测的——我们永远无法确定下一次大流行在何时何地出现。但是，另一场流感大流行是必然的。在这个相互联系的世界中，问题不在于我们是否会再次爆发一场流行病，而在于何时发生。

 为了保护全球人民免受这一威胁，世界卫生组织发布了2019-2030年全球流感战略。这个新战略是最全面和影响最深远的流感世卫组织制定的战略。该战略概述了世界卫生组织、各国和合作伙伴共同努力为流感做好准备、预防和控制的框架。

 1. 另一场流感大流行将发生——这是一个什么时候的问题

我们知道在某个时候还会有另一场流感大流行。1918年，我们有最多的有记载的历史中的毁灭性传染病事件：1918年流感大流行。自 1918 年以来，又发生了三次流感大流行：1957 年、1968 年和 2009 年（H1N1）。风险从动物传播给人类并可能引起大流行的新型流感病毒这是真实的，这是一个警告，我们必须继续为下一次大流行做好准备。

 2. 流感已经是一个重大的健康挑战

每年,估计有1亿例,其中300万至500万为重症病例;其中29万至65万例与流感相关全球呼吸系统死亡。通过加强监测减少季节性流感的影响预防和控制有助于各国为大流行做好准备。

尽你的一份力量帮助预防流感，并接种年度流感疫苗。这是预防流感的有效方法。

 3. 我们比以往准备得更好，但仍然准备不足

虽然多年来有很多工作要做，为应对大疫情做准备，但仍有许多工作要做。重要的是，世界所有卫生系统都做好了预防和控制流感。

我们需要我们的卫生系统强大和健康。

3 Things to know about pandemic influenza

The threat of pandemic influenza is ever-present. A pandemic can arise when a new influenza virus that hasn't affected humans before emerges, spreads and causes illness in humans.

Influenza viruses are unpredictable – we can never be certain of when or from where the next pandemic will arise. However, another influenza pandemic is inevitable. In this interconnected world, the question is not if we will have another pandemic, but when.

To protect people across the globe from this threat, the WHO has released a Global Influenza Strategy for 2019-2030. The new strategy is the most comprehensive and far reaching influenza strategy that WHO has developed. The strategy outlines a framework for WHO, countries and partners to work together to prepare for, prevent, and control the influenza. 

1. Another influenza pandemic will happen – it’s a question of when

We know there will be another influenza pandemic at some point. In 1918, we had the most devastating infectious disease event in recorded history: the 1918 influenza pandemic. Since 1918 three influenza pandemics have occurred - in 1957, 1968 and 2009 (H1N1). The risk of a new influenza virus transmitting from animals to humans and potentially causing a pandemic is real and serves as a warning that we must continue to be prepared for the next pandemic.

2. Influenza is already a major health challenge

Seasonal influenza represents a year-round disease burden. Every year, there are an estimated 1 billion cases, of which 3 to 5 million are severe cases, with 290 000 to 650 000 influenza-related respiratory deaths worldwide. Reducing the impact of seasonal flu through better surveillance, prevention and control helps countries prepare for a pandemic.

Do your part to help prevent influenza and get your annual influenza shot. It is the most effective way to prevent the flu. 

3. We are better prepared than we have been – but still not prepared enough

While there has been much work over the years to prepare for a pandemic, there is still much work to be done. It is critical that all health systems across the world are ready to prevent and control influenza.

We need our health systems to be strong and healthy.
