Health officials have revealed a fresh case of the plague has been discovered in the US, leading to fears of an outbreak. The Wyoming State Veterinary Lab confirmed the Black Death had infected a stray cat in Campbell County. Roughly seven people are infected across the US each year. The news comes shortly after Daily Star Online revealed a terrifying measles epidemic was gripping Europe. Health officials confirmed 17 new cases in Poland in a fresh outbreak – sparking a nationwide warning. The latest outbreak has hit Poland’s capital city Warsaw, with the country’s health minister urging people to vaccinate themselves. Dr Alexia Harrist, of the Wyoming Department of Health, said: “Plague is a serious bacterial infection that can kill pets and people if it’s not treated with antibiotics.” The disease can be transmitted to humans from sick animals and by fleas coming from infected animals. Six people have been exposed in Wyoming since 1978 with the last case investigated in 2008. It is believed the latest spread is due to parents failing to get their children vaccinated. The news comes as Europe battles an epidemic that has reached record highs – with 41,000 cases of measles in the first six months of 2018. At least 40 people have died from the highly contagious virus, reports the World Health Organisation (WHO). WHO say the spike in cases, and fatalities, is higher than any other figure reported throughout a 12-month period so far this decade.
