Two people in China are being treated for plague, authorities said Tuesday. It's the second time the disease, the same one that caused the Black Death, one of the deadliest pandemics in human history, has been detected in the region.
The number of plague cases in Madagascar has almost doubled over the last five days and medical experts project the situation will worsen, with 1,000 cases expected every month if funds aren't rapidly provided, the United Nations said Thursday.
The plague was spreading nearly 3,000 years before previously thought, scientists say after finding traces of the disease in the teeth of ancient people -- a discovery that could provide clues to how dangerous diseases evolve.
The plague has killed a second person in the state of Colorado this year. Pueblo County announced Wednesday that an adult there had died of the disease, which was likely spread by fleas from a dead animal.
The head of the World Health Organization is warning about an 'alarming' plague outbreak in Madagascar that could worsen, particularly as fleas that transmit the disease to humans have developed immunity to insecticide.
An international team of scientists has discovered that two of the most devastating pandemics in human history -- the Plague of Justinian and the Black Death -- were caused by strains of the same bacterium.
