West Nile virus (WNV) epizootiology was monitored from 2002 through 2005 in the area surrounding Grand Forks, North Dakota. Mosquitoes were tested for infection, and birds were surveyed for antibodies. In 2003, WNV was epidemic; in 2004, cool temperatures precluded WNV amplification; and in 2005, immunity in passerines decreased, but did not preclude, WNV amplification.
2002年至2005年期间，对北达科他州大福克斯周边地区的西尼罗河病毒（WNV）动物流行病学进行了监测。检测了蚊子是否感染病毒，并对鸟类进行了抗体检测。2003年，WNV流行；2004年，凉爽的气温阻止了WNV的增殖；2005年，雀形目鸟类的免疫力下降，但并未阻止WNV的增殖。
