In November 2018 a case was reported in Sussex of a mutated flu virus. The flu quickly spread quickly and violently ,within a month over 4 million people had contracted some form of the virus. Hospitals round the country could not cope with the sudden increase in patients and there was no cure they could find. When the victims of the disease began to die, the English Government called for a national emergency.
By then, strands of the disease had travelled across the globe and there were cases being reported in France, Italy, Germany and certain states in the USA. The disease travelled quickly and quarantine was in most cases useless, it was most contagious before the victim began to even show the symptoms.
The symptoms were obvious, coughing up blood, vomiting, diarrhoea, headaches, dizziness, loss of sight and eventually the inability to stand and the victim fell into a coma, followed by death.
Doctors around the world were completely baffled and things began to very quickly deteriorate.
