“…A number of serologic investigations have determined the seroprevalence of CVV in various vertebrates but these studies have mostly been confined to the United States. [21][22][23]37,[46][47][48][49][50][51] For instance, 19% of sheep sampled in Texas in 1981 were seropositive for CVV. 46 In another study, antibodies that neutralized CVV were detected in 84 (95%) of 88 horses, 61 (52%) of 118 cattle, and 6 (27%) of 22 Neutralizing antibodies to CVV were also detected in 100 (72%) of 138 white-tailed deer in Minnesota in 1988 and 1989.…”

“…Although these viruses have not been reported in Mexico, they have been associated with livestock infections in the United States. 47,55 For instance, antibodies to Northway virus were identified in 44% of horses sampled in California during [1968][1969][1970][1971][1972]. 55 The establishment of a continuous entomologic-based arbovirus surveillance program in the Yucatan Peninsula would enable identification of other orthobunyaviruses that may be present in this region.…”

Abstract. To determine the seroprevalence of selected orthobunyaviruses in livestock in the Yucatan Peninsula of Mexico, a serologic investigation was performed using serum samples from 256 domestic animals (182 horses, 31 sheep, 1 dog, 37 chickens, and 5 turkeys). All serum samples were examined by plaque reduction neutralization test using Cache Valley virus (CVV), Cholul virus (CHLV), South River virus (SOURV), Kairi virus, Maguari virus, and Wyeomyia virus. Of the 182 horses, 60 (33.0%) were seropositive for CHLV, 48 (26.4%) were seropositive for CVV, 1 (0.5%) was seropositive for SOURV, 60 (33.0%) had antibodies to an undetermined orthobunyavirus, and 13 (7.1%) were negative for orthobunyavirus-specific antibody. Of the 31 sheep, 6 (19.3%) were seropositive for CHLV, 3 (9.7%) were seropositive for CVV, 4 (12.9%) were seropositive for SOURV, 16 (51.6%) had antibodies to an undetermined orthobunyavirus, and 2 (6.5%) were negative for orthobunyavirus-specific antibody. The single dog was seropositive for SOURV. Four (11%) chickens had antibodies to an undetermined orthobunyavirus, and 1 (20%) turkey was seropositive for CHLV. These data indicate that orthobunyaviruses commonly infect livestock in the Yucatan Peninsula.

“…It belongs to the Bunyamwera serogroup in the genus Orthobunyavirus and was named after the location in northern Utah where it was first isolated from mosquitoes (4). The virus has since been found to be widespread in North and Central America, infecting many species of domestic and wild animals such as deer, cattle, sheep, and horses (5,6,7,8). Epidemiologic studies indicate that CVV can be transmitted via a broad range of mosquito species (9), with the white-tailed deer population as a potential natural reservoir (10).…”

Cache Valley Virus in a Patient Diagnosed with Aseptic Meningitis

et al. 2013

f Cache Valley virus was initially isolated from mosquitoes and had been linked to central nervous system-associated diseases. A case of Cache Valley virus infection is described. The virus was cultured from a patient's cerebrospinal fluid and identified with real-time reverse transcription-PCR and sequencing, which also yielded the complete viral coding sequences. CASE REPORT In mid-September 2011, a 63-year-old woman presented to an upstate New York hospital with complaints of fever, headache, neck stiffness, and photophobia. One week earlier, she had noticed a macular, nonpruritic lesion on her right forearm, about 3 cm in diameter, with central clearing. Three days prior, as the first lesion was fading, a petechial rash developed on her lower extremities that spread to her torso. She then traveled to Pennsylvania for a weekend, and during this time she developed the mentioned fever and symptoms of meningitis. She returned home and went to the Emergency Department (ED) of the hospital the next morning.On physical examination, the patient appeared alert and oriented, with a blood pressure of 148-mm/80-mm Hg, a pulse rate of 87 per min, a respiratory rate of 18 per min, an oral temperature of 37.6°C, and an oxygen saturation of 99% on room air. She had a scattered, bilateral, petechial rash on her thighs; meanwhile, the lesions on her back and abdomen were fading. She had moderate neck stiffness. Her neurologic exam was otherwise normal; there was no evidence of encephalitis, cranial nerve abnormalities, or focal findings.Her medical record included a history of hypertension, hypothyroidism, meningioma, and migraine headaches and of rheumatic fever during childhood. The patient stated that she and her husband frequently camped outdoors. Throughout mid-to late August they camped in Wyoming and Livingston counties in New York state and also embarked on a 5-day camping trip in Dansville, NY, through Vermont and New Hampshire. She lived with her husband, had a cat, and frequently tended to her garden around her home. She had no knowledge of any sick contact.Her white blood cell count on presentation was 5,700/l, with a normal differential. Hematocrit was normal at 42%, and platelets were normal at 212,000/l. Computed tomography of the head without contrast showed mild atrophy without evidence of acute intracranial abnormality. Blood cultures were drawn, and she was sent home on doxycycline. The patient returned to the ED the following day with new complaints of nausea and vomiting in addition to the previously reported symptoms.The patient was admitted to the hospital with a preliminary diagnosis of aseptic meningitis. A lumbar puncture was performed, and the cerebrospinal fluid (CSF) showed 216 nucleated cells, with 91% lymphocytes, 7% monocytes, 1% basophils, and 1% polymorphonuclear cells. CSF chemistries were normal, with a glucose concentration of 60 mg/dl (56% of the serum level) and protein of 46 mg/dl. No microorganism was seen in the CSF by Gram stain. Magnetic resonance imaging of the brain showed only a ...

“…Cache valley virus has a wide geographic distribution in North America (Blackmore and Grimstad, 2008), whereas Tensaw virus is found predominantly in the Southeastern United States (Bigler et al, 1975) and Northway virus in Alaska and California (Campbell et al, 1990(Campbell et al, , 1991Walters et al, 1999;Zarnke et al, 1983). Recent evidence suggests these host ranges may not be as restrictive as earlier thought (Sahu et al, 2002). The amplifying hosts for all of these viruses are unclear, however antibodies recognizing Cache valley virus have been found in Desert cottontails (Sylvilagus audubonii), Eastern cottontails (Sylvilagus floridanus), and Black-tailed jackrabbits (Lepus californicus) (Blackmore and Grimstad, 2008).…”
