A 64-year-old grandfather in Muncie, Indiana, has been in a coma for 19 days after having a heart attack caused by West Nile earlier this month.
Danny Duncan, from Delaware County, went to the emergency room three weeks ago fearing a heart condition – but doctors diagnosed him with the mosquito-borne virus.
Three days later he suffered a cardiac arrest and is now in a coma, on life support, being fed through a tube.
His is one of two West Nile cases reported this week.
On Tuesday, health officials in Pittsburgh warned that an elderly woman was hospitalized with the disease in mid-August. She has since recovered.
Officials in both states where the new cases were reported are urging residents to be cautious while spending time outdoors and reminding them that the mosquito season will not end until October.
