Here's the scary part about working with dangerous viruses. There's always a fear of contracting it and dying from it. A young researcher from San Francisco has died after being infected by a highly virulent strain of meningococcal disease he was studying.

The US Centers for Disease Control and Prevention has announced that it suspects Richard Din, 25, became fatally infected with an agent from his own laboratory. A biopsy sample from Din is now being tested to confirm the news, reports the Guardian.

Din's research was focussed on developing a vaccine to protect against the incredibly dangerous bacterium called Neisseria meningitidis—a strain of bacteria that causes meningococcal disease, and leads to meningitis and bloodstream infections.

Dozens of people—including relatives, friends and co-workers—are being provided with antibiotics as a precaution. Din died less than a day after falling ill so lets hope this doesn't become an epidemic.  [The Guardian]
