they brought any sort of lumber they have. we're just trying to divert the water into the street. we have police department on scene shutting off -- closing off streets to traffic and water department on scene hopefully shutting down the water. >> reporter: several blocks around keith and key are all closed down. they expect they will be closed down for hours to come. the next step for the water public utilities commission is going to be digging up the pavement so they can check on that pipe and then repair it. they expect that will take at least four to six hours. in san francisco, tiffany wilson, abc 7 news. >> thank you, tiffany. it's known as the enterovirus, a respiratory infection spreading across the country. for the first time it's been detected in northern california. abc 7 news reporter laura anthony says doctors and parents are on high alert. >> we do have our first case. >> reporter: solano county health officials are the latest to confirm they, too, have had a case of enterovirus d-68 in a
