Human papillomavirus serology can be applied to determine past or present HPV infection (de Villiers, 1992; Kirnbauer et al, 1994).
Human papillomavirus serology was performed using retrospectively identified sera from 20 head and neck cancer patients ('training set') collected at Brown University that were known to be positive for HPV16 (N=10) or HPV18 (N=10) Abs defined by the competitive Luminex immunoassay (cLIA; VLP Ab+) developed by Merck (West Point, PA, USA) (Smith et al, 2008c).
We obtained results on human papillomavirus serology for 2366 cases and controls (663 squamous cell carcinoma, 898 basal cell carcinoma, 805 controls) from whom a plasma sample was collected (excluding seven squamous cell carcinoma cases, two basal cell carcinoma cases, and seven controls with insufficient or unprocessed samples).
Previous evidence for C-CHFV in Kenya is limited and based on serology (human and bovine) and two isolations of C-CHFV from non-human sources (1, 2).
The patient was not a carrier of hepatitis B or C, and her human immunodeficiency virus serology was nonreactive.
Patients with acquired immunodeficiency syndrome (AIDS -related lymphomAIDS -relateduman immunodeficiency virus serolymphoma hearing impositive were excluded.
The exclusion criteria were uncontrolled hemorrhagia, recent (< 48 hours) cardiac surgery, recent(< 48 hours) resuscitation, platelets < 20,000/mm, positive human immunodeficiency virus serology, morbid obesity and pregnancy.
Human papillomavirus (HPV) serology is a main factor for designing vaccination programs and surveillance strategies; nevertheless, there are few reports of HPV seroprevalence in the general population, especially in Latin America.
Morbidity in children in this outbreak was substantially higher than in adults, and subsequent outbreaks in Israel in 1952 and 1953 occurring primarily in adolescents and adults were also identified as WNV, on the basis of isolation of the virus from human cases and serology from human cases and chickens [ 2, 6, 7].
Patients who had autoimmune disease, malignancy, hepatitis in active conditions, currently used steroids or immune-suppressants, had positive human immunodeficiency virus HIV) serology, and had any kind of acute infection within one month were excluded.
