Two more planes full of sick people land in the United States bringing the zombie apocalypse one step closer

Both of todays flights were on American Airlines: one from Munich and another from Paris. They landed at Philadelphia International Airport with about a dozen people in total on board who felt sick, according to a statement from the airport. That in itself is not that unusual because of the dry air and the prevalence of cat dander on planes, Allen Parmet, an aerospace medicine expert, told The Verge in an interview yesterday: Its actually pretty common to have somebody coughing in a plane.But to be safe, all passengers on the two flights totaling about 250 plus crew were held for a medical review and the CDC was notified, the Philadelphia International Airport said in a statement. No one was running a fever, so they will be released, the CDC said. The people who were sick on the flight should hear back about their test results in 24 hours.
