A woman in the UK has been diagnosed with a tick-borne viral disease that has a 40% chance of killing those it infects.
Crimean-Congo haemorrhagic fever is a viral disease usually transmitted by ticks and livestock animals in countries where the disease is endemic.
Like Ebola, Crimean-Congo haemorrhagic fever (CCHF) has a high mortality rate and presents with similar symptoms at the start of infection, but unlike Ebola it does not spread easily from human to human.
