Lassa

UK officials are checking for any possible cases of Lassa fever after a traveller to England, who has since returned to Nigeria, is known to have been infected.

Not long after, he was sent to Sierra Leone to help investigate an outbreak of Lassa fever, a virulent hemorrhagic virus.

Other scientists had discovered that this gene was critical for the Lassa virus to enter cells.

They are also testing EVEscape on understudied viruses such as Lassa and Nipah, two pathogens of pandemic potential for which relatively little information exists.

But when Garry and his colleagues studied the blood of Lassa survivors, they discovered something even better: potent antibodies capable of blocking the virus from entering cells.
