The Health Ministry warned the public that passengers on flights to and from Kiev are at risk of catching the measles, in a statement issued on Monday. Many Israelis travel to Ukraine during this season to visit the town of Uman, where Rebbe Nachman of Breslov is buried.On September 12, a passenger suspected of having the measles arrived in Israel from Kiev via Amsterdam having flown on Ukraine International Airlines flight PS1010 and KLM Royal Dutch Airlines flight KL461, the statement read. On that same date, a passenger arrived on UIA flight 779 and is suspected of having measles as well.Measles is one of the most serious infectious diseases. It is highly contagious and can be transmitted airborne from coughs and sneezes. Symptoms typically appear seven to 14 days after a person is infected and can include high fever, coughing, runny nose, red or watery eyes and sometimes Koplik spots – tiny white spots which can appear in the mouth two or three days after the onset of symptoms. Complications are common – from diarrhea to pneumonia, bronchitis and brain inflammation.
