CNN —The oldest known plague victims date back to around 5,000 years ago in Europe. Genetic time travelGenetic information about pathogens can be preserved in human DNA, allowing scientists to time travel to find out about ancient diseases and how they evolved. (It’s also not possible to know for sure whether the people studied died of the plague — only that they were infected.) Karl-Göran SjögrenNonetheless, the study authors said their findings did not necessarily suggest a swift and deadly plague epidemic. Instead, the team found evidence of three distinct infection events, plus different variants of the bacterium that causes plague.

☆ Which diseases can pets transmit to their owners?

CNN: What types of diseases can household pets like cats and dogs transmit to humans? Dr. Leana Wen: Just as humans can transmit diseases to other humans, animals can transmit diseases to others in their own species. Sometimes, animals can transmit diseases to other species, and that includes humans with whom pets have had close contact. These diseases spread when a person is bitten by an infected tick that has fed off an infected animal. It’s not known how the man who died from Alaskapox contracted it, but a possible route is an infected animal biting the individual or exposure of an infected animal to an existing break in the man’s skin.

☆ Plague: Oldest known cases in Britain uncovered in mass burial

CNN —A team of researchers excavating mass burial sites in England have detected the DNA of the bacteria that caused the plague in human skeletal remains — and they are the oldest known cases of the disease in Great Britain. The bacterial DNA is thousands of years more ancient than the oldest strain uncovered prior to this latest finding. When it comes to the disease, there is a lot that scientists still don’t know — including how it spread, Swali said. And science may never truly know the severity of the plague 4,000 years ago when it came to humans, Roberts said. And while there are historical records of plague outbreaks, ancient DNA could potentially give us a look even further back, Swali said.

As we shifted to indoor city life, outbreaks and pandemics whipped through society with alarming regularity. But technological changes have allowed us, in the developed world at least, to prevent many such pandemics. In the developed world, they are cheap, ubiquitous and mundane. Yet these technologies fight a whole host of outbreaks without our needing to know each pathogen’s name. Epidemics like cholera still occur in the developing world, but this ‌‌is a matter of a lack of global political will, not a lack of technological way.

☆ The Black Death permanently altered the human immune system, study says, leaving a vulnerability that persists 670 years later

The Black Death which ravaged Europe 670 years ago may still be harming humans today a study found. A scientist holds up a tooth from human remains buried in the 1300s. The Black Death, one of the greater killers in human history, was the perfect model to look at, Lee said. In just five years between 1346 and 1350, the Black Death, a pandemic caused by the bacteria Yersinia Pestis, killed tens to hundreds of millions of people, many before they were old enough to have children.

☆ Cele mai letale pandemii din istoria umanităţii

De-a lungul istoriei pojarul a provocat moartea a 200 de milioane de persoane ca urmare a inflamaţiei pulmonare sau a meningelui. Aşa-numita "gripa spaniolă" din 1918 a provocat tot atâţia morţi ca Primul Război Mondial, iar unii experţi asigură că acest conflict mondial s-a încheiat din cauza epidemiei. Infecţia cu virusul imunodeficienţei umane (HIV) a fost raportată pentru prima dată în anul 1981 în Statele Unite. Până în prezent, SIDA a provocat moartea a 25 de milioane de persoane şi rămâne un mare risc pentru societate. A fost cea de-a treia pandemie de gripă din secolul XX şi s-a declanşat în 1968, când a provocat moartea a aproape un milion de oameni.
