A student in the West Genesee School District has been diagnosed with enterovirus-D68, the rare virus that can cause serious breathing problems in children. Dr. Christopher Brown, the district’s superintendent, notified parents today in a letter posted on the district’s website. ” … we will do everything possible to help keep you informed and prevent the spread of the virus,” Brown said in the letter. “We will wash and disinfect our facility, classrooms and materials regularly.” Enterovirus-D68, EV-D68 for short, has been sickening youngsters nationwide. The virus, which can cause respiratory illness, primarily affects children with asthma. Brown’s letter did not disclose the student’s age, school or condition. Upstate Golisano Children’s Hospital announced Friday it had admitted three Central New York children under age 10 who tested positive for EV-D68.The hospital said today it has seen a spike in the number of children being admitted for treatment of respiratory virus. Symptoms of the virus begin like a cold with runny nose, coughing, congestion, fever and body/muscle aches. Some children, particularly those who have asthma, may develop wheezing and breathing difficulties. In his letter, Brown said many of these symptoms could be indicators of a common cold. He advised parents to contact their doctors if they have concerns about their children. He said children should be free from fever and vomiting for 24 hours before returning to school.
