In 2001, 2 horses (illness onset Nov) from Rockingham Co (SW, on coast), 83 of 889 birds (first one found May 11, most from southern NH) and 3 positive mosquito pools (Rockingham and Strafford Co, both in SW NH) tested WNV-positive.
In 2000, there were 7 WNV-positive birds of 405 tested.
[New Hampshire Dept of Health and Human Services West Nile Virus Page: http://www.dhhs.state.nh.us/DHHS/BCDCS/West+Nile+Virus/default.htm] - New Jersey: (Updated Sept 23 2002) WNV has been detected in 20 of 21 counties in NJ. As of Sept 23, 4 human cases had been reported by the NJ Dept of Health and Senior Services while CDC reported 3 cases:
1) 77-year-old man from Ewing, Mercer Co (hospitalized Aug 21; ann Sept 5)
2) 62-year-old man from Mercerville, Mercer Co (hospitalized Sept 1; ann Sept 6)
3) 39-year-old man from Trenton, Mercer Co (onset Aug 26; hospitalized Sept 2; ann Sept 13)
4) 53-year-old man from Jersey City, Hudson Co (onset Sept 2; hospitalized Sept 17; ann Sept 23) As of Sept 17 2002, 294 of 5952 mosquito pools in 19 counties, 13 horses and 706 WNV-positive birds in 20 counties tested WNV-positive. The first birds were collected between Apr 16-May 3 2002.
Black bears in NW New Jersey, tested in Feb and Mar 2002 as part of a neutralizing antibody serosurvery, tested positive in 3 of 51 samples (Rutgers University).
In 2001, WNV was detected in all NJ counties (compared to 20 of 21 NJ counties in 2000). The first announcements were May 7 in crows, June 8 in mosquito pools and Aug 8 in sentinel chickens. In sum, WNV was detected in 1,073 crows (of 1,553 birds tested, mostly crows), 357 mosquito pools (of 4,937 tested) and 31 sentinel chickens (Monmouth Co) in 2001. Although mosquitoes were expected to be active in NJ until early Nov, the Oct 11 mosquito surveillance results included no WNV-positive mosquito pools.
In 2001, there were 12 confirmed human cases (1 fatality) of the 102 humans tested, as compared to 6 human cases (1 fatality) in 2000. The first person in 2001 was hospitalized late July. The fatality was a 45 year old man from Carteret (likely bitten late July/early Aug; hospitalized Aug 21; developed complications, died Oct 4; ann Nov 14) [More].
2001 human cases in NJ:
1) 72-year-old woman from Bergenfield (Bergen Co--NE NJ, near NYC; hospitalized late July, ann Aug 29).
2) 72-year old man from Camden City (Camden Co, hospitalized Aug 23; ann Sept 19)
3) 66-year old man from Edison Township (Middlesex, hospitalized Aug 31; ann Sept 19)
4) 78-year old woman from Westfield Township (Union; hospitalized Sept 5; ann Sept 19).
5) 72-year old man from Newark (Essex Co, northern NJ; likely bitten mid-Aug with onset of illness late Aug; ann Oct 12.
6) 38-year old woman from Pennsauken (Camden Co, southern NJ; likely bitten mid-Aug, with onset of illness late Aug; ann Oct 12). Other cases involving people in their 30s, 40s and early 50s had been reported in CT, NY and FL.
7) 45-year-old Carteret man died Oct 4 (ann Nov 14).
8) 75 year-old Harrison (Hudson Co) woman (most likely infected late July/early Aug; hospitalized mid-Aug; ann Dec 5). Her case presented some twists on the typical investigation: Preliminary infectious disease tests were negative and the patient was then tested and treated for her chronic heart condition. Subsequent tests showed WNV infection, but were inconclusive as to whether the infection was during this season or from the previous season. CDC later confirmed that the infection was from the 2001 season on the basis of an increase in antibody production from the initial to a convalescent serum, as is consistent with a more recent infection [More].
9) 41-year old man from Pennsauken, Camden Co (confirmed WNV-positive by CDC Feb 8 2002). Husband of the 38-year old woman confirmed WNV-positive in Oct. Both were ill at the same time though he was not hospitalized.
10) 81-year old man from Cranford (hospitalized Sept 21; confirmed WNV-positive Apr 25 2002 by CDC).
11) 34-year old from Hillside (illness onset Sept 22; confirmed WNV-positive Apr 25 2002 by CDC).
12) 54-year old from Paterson (hospitalized Sept 27; confirmed WNV-positive Apr 25 2002 by CDC) [More].
According to USDA APHIS, in 2001 there were 33 equine cases in 10 counties (15 fatalities), many were reported late autumn or later.
Every county in NJ received funding from a $2.4 million tire round-up program in 2001 (plus an additional $100,000 for clean-up of 80,000 tires at Nearpara Rubber in Hamilton) and the state proposed an additional $2.4 million in the fiscal year 2002 budget for tire clean-up activities.

A Nov 24, 2001 article in the New York Times reported that the families of 2 persons in Nassau Co NY who allegedly died of WNV were planning to sue the county because mosquito adulticides were not used for WNV control. The County Health Dept spokesperson said that after the cases were diagnosed surveillance was increased in the area, but they did not find evidence of mosquito infestation to justify spraying. One death occured Nov 22 (77-year-old man) and the other (71-year old woman) on Oct 26; both people resided in East Meadow, Nassau Co, Long Island in NYS [More].
In 2001, 22 equine cases were reported from Orange (1), Nassau (4) and Suffolk(17) counties, up from 15 reported Oct 26, 12 reported Oct 5 and 8 reported on Sept 28.

NYC DOH--WNV: http://www.ci.nyc.ny.us/html/doh/html/wnv/wnvhome.html ] - North Carolina: (Updated Sept 23 2002) On Sept 18 2002, the NC Dept of Health and Human Services confirmed the first human case of WNV in NC in a 80-year-old man from Henderson in Vance Co. On Aug 20 2002, the NC DHHS reported that the 2nd set of tests on a NC visitor (who was sick before entering NC on Aug 5) had proved inconclusive as to whether the WNV infection was recent or from a past infection. As of Sept 18 2002, 107 birds from 30 counties tested WNV-positive in central and northeastern NC and mostly from Mecklenburg Co. WNV-positive mosquito samples were also found in Mecklenburg Co. The first WNV-positive bird was confirmed June 17, 2002 from Mecklenburg Co (Charlotte Metro Area).
WNV was first detected in 2000 in a dead crow found at Jordan Lake State Park in Chatham Co (central NC). The first detection of in 2001 was a dead blue jay found in Cabarrus Co (borders Mecklenburg Co in central NC) in Aug, ann Sept 17. In 2001, 6 horses in 4 counties tested WNV-positive (2 fatalities). The first detections in horses were from Hyde Co (1) and Camden Co (1) both on the Atlantic coast (ann Oct 9). A total of 8 birds (6 crows and 2 blue jays) and 3 sentinel chickens were confirmed WNV-positive for 2001.
An Oct 10, 2001 statement from the NC Division of Public Health epidemiologist suggested that the suspected human case (ann Oct 3) was unlikely because the test results probably reflected a pre-existing flavivirus infection (probably yellow fever vaccine-induced antibody). The suspected case involved a 66-year old Florida man traveling through NC and other states in a recreational vehicle. He had spent several overnights near Greenville in Pitt Co, in the eastern part of the state, where he had noted a dead bird under his van. If this case had been confirmed, it would have been the first human case in NC, [More].
[Public Health in NC--WNV: http://www.schs.state.nc.us/epi/oee/wnv.html ] - North Dakota: (Updated Sept 23 2002) As of Sept 23 2002, WNV has been detected in 53 of ND's 54 counties. There have been 12 human cases with 2 fatalities. WNV has also been confirmed in 530 horses and 43 birds. WNV was detected for the first time ever in North Dakota in a young gelding from Grand Forks County (E. ND, on Minnesota border). The horse began showing signs of West Nile Virus on June 30 2002 and was euthanized July 2, 2002. Confirmation of the positive preliminary result is expected this week [More].
Active surveillance began in May 2000. In 2001, 6 humans, 4 birds, 7 horses, and 14 mosquito pools tested WNV-negative.
