The native people of Mexico experienced an epidemic disease in the wake of European conquest (Figure 1), beginning with the smallpox epidemic of 1519 to 1520 when 5 million to 8 million people perished. The catastrophic epidemics that began in 1545 and 1576 subsequently killed an additional 7 million to 17 million people in the highlands of Mexico (1–3). Recent epidemiologic research suggests that the events in 1545 and 1576, associated with a high death rate and referred to as cocoliztli (Nahuatl for “pest”), may have been due to indigenous hemorrhagic fevers (4,5). Tree-ring evidence, allowing reconstructions of the levels precipitation, indicate that the worst drought to afflict North America in the past 500 years also occurred in the mid-16th century, when severe drought extended at times from Mexico to the boreal forest and from the Pacific to Atlantic coasts (6). These droughts appear to have interacted with ecologic and sociologic conditions, magnifying the human impact of infectious disease in 16th-century Mexico. The epidemic of cocoliztli from1545 to 1548 killed an estimated 5 million to 15 million people, or up to 80% of the native population of Mexico (Figure 1). In ab

Congolese health officials and their international partners expect the fight against Ebola to drag on well into next year. The biggest worry is that, unchecked, the epidemic could reach Goma, the regional capital. “If it hits Goma, we’re done for,” said Dr. Jean-Christophe Shako, the director of a local Ebola response team whose tasks require negotiating with the militia so that health workers can enter their territories and have their safety guaranteed. The city sits on a busy border with Rwanda and has an international airport that could disperse the disease globally.
The question is at the heart of investigations by Congress and federal agencies into whether an American gun manufacturer is entangled in the shadowy world of arms smuggling and wildlife poaching.
Fake news threatens our democracy. Fake medical news threatens our lives.
If Russia does not cease its alleged violations of the INF Treaty within 60 days, Washington will withdraw from the treaty. Credible evidence for those alleged violations is as absent today, as sound proof of the alleged Iraqi weapons of mass destruction were in the run-up to the invasion of Iraq. The western debate is still ignoring solid Russian evidence that the USA is violating the INF Treaty with the installation of NATO’s missile defense systems in Romania and Poland. Yesterday, NATO foreign ministers blamed Russia for the abrogation of the treaty. Berlin seeks to avoid the installation of US medium-range missiles in Europe, because they would restrict the EU’s planned military autonomy. Government advisors are suggesting other armament measures against Russia.
