An international research team has provided the first scientific evidence that deadly emerging diseases have risen steeply across the world, and has mapped the outbreaks’ main sources. They say new diseases originating from wild animals in poor nations are the greatest threat to humans.

Nonhospital health-care workers at substantial risk of exposure to bloodborne pathogens

In one of the largest studies of its kind, researchers from the Columbia University Mailman School of Public Health assessed the risk of exposure to bloodborne pathogens among non-hospital based registered nurses (RNs), and found that nearly one out of 10 of the more than 1100 nurse participants reported at least one needlestick injury in the previous 12 months.

Pathogens use previously undescribed mechanism to sabotage host immune system
