Fabian Ruiz is considered a doubt for Napoli’s next match against Roma after the midfielder reportedly contracted swine flu.
According to Il Mattino, the breathing problems linked to Fabian’s stint in hospital were caused by a bout of the H1N1 virus.
The newspaper writes that despite the Spaniard being discharged and no longer showing any symptoms, there is a risk that his illness could spread throughout the squad.
Carlo Tascini, an expert on infectious diseases, told Il Mattino: “The H1N1 virus is a real disease that has been around for over 10 years.
“It can cause cardiopulmonary complications and affects millions of people every year.”
The 22-year-old was ruled out of Napoli’s 4-2 win against Udinese last weekend with the flu, which was seemingly innocuous as he was then handed his first-ever Spain call-up.
