Three British citizens were brought back to the UK from Sierra Leone to be medically assessed after coming into close proximity with two individuals with Lassa fever. 

Public Health England stated that the three citizens will be given the required treatment if necessary- getting in contact with 15 others who were noted to have been in proximity to the Dutch Lassa fever.

Dr Jake Dunning of Public Health England, stated that the fever is not very contagious between people, so the public risk remains low.
