Another medically fragile child with respiratory illness at the Wanaque Center for Nursing and Rehabilitation died Saturday, bringing the total deaths among facility residents to nine, state officials said.
The facility, which includes a pediatric center, has been instructed not to admit new patients until the outbreak ends, the department said. A staff member at the facility also became ill as part of the outbreak but has since recovered.
According to health officials, the child had a confirmed case of adenovirus and became ill before October 22.
Those affected range in age from toddlers to young adults, with the vast majority under age 18.
Her mother says she was not made aware of the outbreak until Monday, the day before her daughter died and nearly three weeks after she was admitted to St. Joseph's Medical Center, NorthJersey.com reports.
"Unfortunately, the particular strain of adenovirus (#7) in this outbreak is affecting medically fragile children with severely compromised immune systems", Kirgan said.
On Tuesday the New Jersey Department of Health announced the death of six pediatric residents at the center and the infection of 12 additional residents.
The state Department of Health Communicable Disease Service has been on site monitoring the outbreak. The CDC is also investigating the outbreak.
The strain of adenovirus is associated with communal living arrangements, it said.
In a statement, the facility said it "promptly notified all appropriate government agencies when the virus was initially identified".
Most adenovirus infections are mild, with symptoms usually lasting about 10 days, according to the CDC.
This remains the last day when a patient showed new symptoms.
The bacterium can cause pneumonia or serious blood or wound infections.
The viruses typically spread from close personal contact such as touching or shaking hands, through the air by coughing and sneezing, and touching objects or surfaces that have the viruses on them before touching one's mouth, nose, or eyes.
Still, Schaffner doesn't think people need to be anxious about adenoviruses.
