A small vial containing a potentially harmful strain of virus has gone missing from a Texas laboratory, it was revealed today.

The vial, which contains a strain of the Guanarito virus, had been locked in a bio-hazard freezer within the University of Texas’ Medical Branch campus.

The strain of virus is part of a family of diseases that caused deadly outbreaks in Venezuela and could cause hemorrhagic fever.

Government officials have made studying the strain a priority as it can potentially be used by terrorists in a contagion attack.

Upon discovery that one out of the five vials at the lab was missing, officials contacted the Centers for Disease Control and Prevention.
