They can range from flu-like symptoms to sepsis.Infection can usually be treated effectively with antibiotics and is recommended for a minimum of three weeks.But there can be long-term side effects include amputation from gangrene, heart attack, and kidney failure.The faster the infection is diagnosed the better the chance of survival. About 30 percent of all those infected die.Source: CDCThis then progressed to his kidneys and liver shutting down and blood clotting in his blood vessels, starting to rot his skin away.These horrific effects then tragically led to a cardiac arrest.The deadly infection he contracted is most often triggered by bites, according to doctors.Medics were surprised it happened after licking alone, as the bug is rare and, according to one study in the Netherlands, affects only one in every 1.5million people.It is fatal in around 28 to 31 per cent of cases.The man did not even have an open wound to begin with, which they said could have explained the more serious illness.The team, led by Dr Naomi Mader, wrote: "Pet owners with flu-like symptoms should urgently seek medical advice when their symptoms exceed those of a simple viral infection, which in this case were (breathing problems and rash)."Physicians confronted with such patients should ask about contact with dogs and cats."We pay for your stories!
