New In This Update
To date, 1 test was positive, 24 were negative and 23 are pending.
New Jersey's first WNV positive case of the season is a 72-year old Bergenfield woman. Testing on serum and spinal fluid samples completed Aug. 29 by the New Jersey Department of Health and Senior Services laboratories were consistent with the WNV diagnosis. Final confirmation of this case will be made by the federal Centers for Disease Control and Prevention (CDC) within a few weeks. The patient was admitted to Holy Name Hospital in Teaneck at the end of July with symptoms consistent with WNV infection, including a fever greater than 100 degrees, muscle weakness and malaise. While her mental status has improved, she continues to experience weakness in her legs and is receiving rehabilitative therapy.
Human testing for WNV is being conducted at the New Jersey Department of Health and Senior Services' Public Health and Environmental Laboratory in Trenton and at public health labs in other states. Testing results are sent to the CDC for confirmation.
Doctors of patients with symptoms that do not meet WNV testing criteria have the option of sending samples of their patients' blood to private laboratories for analysis using the St. Louis Encephalitis (SLE) screening test. Since SLE and WNV are closely related viruses, a WNV case will most likely react to a SLE test. The department has not been notified of any positive SLE tests to date
