Please find attached the NJDOH vector-borne surveillance report for week 39.
- To date, there have been 28 WNV human cases reported in 11 counties. There are 8 confirmed cases (1 fatality) reported in Bergen (2), Burlington (1), Camden (2), Essex (1), Gloucester (1), and Somerset (1); 20 probable cases in Bergen (1), Burlington (5), Camden (3), Cumberland (1), Essex (3), Middlesex (1), Ocean (1), Monmouth (4), and Mercer (1) counties, awaiting confirmatory testing; and 3 asymptomatic viremic blood donors reported in Burlington and Monmouth (2) counties. In a typical year, there are 8 human WNV cases reported. Reports of human cases have increased starting on week 34.
- West Nile virus (WNV) has been detected in 14 mosquito pools so far this week and to date, 932 pools have tested positive for WNV. WNV activity this season has exceeded 5-year averages and has been detected in all counties except Salem but has been decreasing starting in week 35. WNV has also been detected in 6 birds.
- 25 pools have tested positive for EEE in southern N.J., which is higher than the same period in 2020, but is consistent with 5-year averages. The variety of mosquito species that have tested positive, however, is of concern. There have been no EEE human cases but 3 EEE positive horse cases reported in 2021.
- To date, 6 pools have tested positive for JCV and 1 human case was reported earlier this season in Sussex County.
