Emerging during the Crusades, it had its first impact in Europe in 1489, in Spain. [178][179] Their ability to spread efficiently enough to cause a pandemic is limited, however, as transmission of these viruses requires close contact with the infected vector, and the vector has only a short time before death or serious illness.

There have been a number of particularly significant epidemics that deserve mention above the "mere" destruction of cities: Encounters between European explorers and populations in the rest of the world often introduced epidemics of extraordinary virulence. Comments on pandemic.

According to Peter Daszak, the chair of the group who produced the report, "there is no great mystery about the cause of the Covid-19 pandemic, or of any modern pandemic. [21], Historically, measures of pandemic severity were based on the case fatality rate. Dengue Fever: Dengue is spread by several species of female mosquitoes of the Aedes type, principally A. aegypti. The "exponential rise" in consumption and trade of commodities such as meat, palm oil, and metals, largely facilitated by developed nations, and a growing human population, are the primary drivers of this destruction.

[189] Regular influenza viruses establish infection by attaching to receptors in the throat and lungs, but the avian influenza virus can attach only to receptors located deep in the lungs of humans, requiring close, prolonged contact with infected patients, and thus limiting person-to-person transmission. This warrants monitoring and reporting of suspicious cases of atypical pneumonia. The recommended distance from other people is six feet, a practice more commonly called social distancing. [186], In October 2005, cases of the avian flu (the deadly strain H5N1) were identified in Turkey. Fact Sheet: Tuberculosis in the United States.
