Generally, seasonal flu is a remnant of a strain of the flu virus that once caused a pandemic.

But to understand the true biologic sense of the power of microbes, we must never forget that we are the ones trying to anticipate and respond to their evolution, not the other way around.

As another example, in many healthcare settings, up to 35 percent of nurses are the parents of school-age children, and up to 20 percent of those would have to stay home with their children because they have no childcare alternatives. So, closing schools can have the effect of losing 20 percent of our vital nursing workforce in a time of medical crisis, before we even consider those that we will lose to illness itself.

The CDC and three other research groups submitted a paper for publication in the journal Science detailing how they had reconstructed the 1918 H1N1 influenza virus, using virus genes that had been identified in lung samples of patients who died during the 1918 pandemic.

In any pandemic, effective leadership is critical, and the first responsibility of the president or the head of any nation is to offer accurate and up-to-date information, provided by public health experts, not agenda-oriented political operatives.

The battle lines are well drawn: the microbes’ genetic simplicity and evolutionary swiftness against our intellect, creativity, and collective social and political will. We cannot overwhelm the pathogens, because they so vastly outnumber and outmaneuver us. Our survival depends on outsmarting them.

Like Abraham Lincoln, I am a firm believer in the people. If given the truth, they can be depended upon to meet any national crisis. The great point is to bring them the real facts.

In a 2015 TED Talk, Bill Gates asserted, “If anything kills over 10 million people in the next few decades, it’s most likely to be a highly infectious virus rather than a war. Not missiles, but microbes.

En Monrovia, la gente llevaba a sus familiares enfermos para que los curaran en la iglesia. Hasta cuarenta pastores murieron tras contraer el virus por haber atendido a sus congregantes aquejados.

Irónicamente, el modo en que hemos organizado el mundo para mejorar la eficiencia, el desarrollo económico y nuestro estilo de vida - los esfuerzos generalmente útiles para transformar el planeta en una aldea global- nos ha hecho más susceptibles que en 1918 a los efectos de las enfermedades infecciosas.
