Third Human Case Of West Nile Virus Reported In Mass.

BOSTON (CBS) – The third human case of West Nile Virus has been announced by the Massachusetts Department of Public Health. A man in his 60s from Middlesex County was exposed to the virus last month. “We continue to emphasize the need for people to protect themselves from mosquito bites,” said Public Health Commissioner Monica Bharel, MD, MPH. “Although mosquito populations are declining, some risk will continue until the first hard frost.” CHECK: Map Of Communities At Risk For EEE, WNV The other two human cases of WNV this year were another man in his 60s from Middlesex County and a man in his 50s from Plymouth County. There have also been 12 human cases of mosquito-borne Eastern Equine Encephalitis in Massachusetts this year.

BOSTON (CBS) — A man in his 70s has become the second person to die and the 10th person to be diagnosed with the Eastern Equine Encephalitis (EEE) virus in Massachusetts, the Department of Public Health said Friday. The man was a Freetown resident, according to the town. There are 35 communities at critical risk, 40 at high risk, and 128 at moderate risk for EEE.

Health officials urged the public to use bug spray, reduce exposed skin and stay indoors from dusk to dawn when m...

lmair Flaviviruses are the most medically relevant group of arboviruses causing a wide range of diseases in humans and are associated with high mortality and morbidity, as such posing a major health concern. Viruses belonging to this family can be endemic (e.g., dengue virus), but can also cause fulminant outbreaks (e.g., West Nile virus, Japanese encephalitis virus and Zika virus). Intense research efforts in the past decades uncovered shared fundamental strategies used by flaviviruses to successfully replicate in their respective hosts. However, the distinct features contributing to the specific host and tissue tropi...

Semin Neurol 2019; 39: 419-427 DOI: 10.1055/s-0039-1687839There are many arthropod-borne viruses (arboviruses) capable of neuroinvasion, with West Nile virus being one of the most well known. In this review, we highlight five rarer emerging or reemerging arboviruses capable of neuroinvasion: Cache Valley, eastern equine encephalitis, Jamestown Canyon, Powassan, and Usutu viruses. Cache Valley and Jamestown Canyon viruses likely circulate throughout most of North America, while eastern equine encephalitis and Powassan viruses typically circulate in the eastern half. Usutu virus is not currently circulating in North America,...

BOSTON (AP) — Massachusetts public health officials say laboratory testing has confirmed the state’s eighth human case of eastern equine encephalitis this season. The state Department of Public Health said Friday the latest case of the mosquito-borne disease is in a man in his 50s from northeastern Bristol County. Of the previous seven cases, one was in a 5-year-old girl, and another in adult woman was fatal. Check: Map Of Communities At Risk In addition to the eight human cases of EEE, there have also been eight confirmed cases of EEE in animals and one human case of West Nile virus. There are 35 communit...

West Nile virus (WNV) is an arbovirus, which is transmitted by mosquitoes. Transmission peaks in the late summer and early fall. In 2018, Virginia had 47 total cases of WNV, 37 of which were neuroinvasive with 7 reported deaths. Risk factors for neuroinvasive WNV include advanced age, history of organ transplantation, and hematologic malignancy especially those actively undergoing chemotherapy. Here we discuss a case of a patient with stage 4 follicular cell lymphoma with recent chemotherapy and radiation therapy, who was found to have severe neuroinvasive seronegative WNV encephalitis with flaccid paralysis.

CONCLUSIONS: Our case indicates that West Nile Virus infections can trigger autoimmune encephalitis. Our finding expands the spectrum of autoimmune conditions that can develop following an infection. Whether the autoimmunization process is due to molecular mimicry or due to the expansion of natural autoantibody clones merits further investigation.

R. Singh Treatment drugs, besides their specific activity, often have multiple effects on the body. The undesired effect of the drug may be repurposed as therapeutics, saving significant investigative time and effort. Minocycline has anti-cancer, anti-oxidant, anti-inflammatory, and anti-apoptotic properties. Presently, minocycline is also known to show anti-viral activity against Influenza virus, Japanese encephalitis virus, Simian immunodeficiency virus, Human immunodeficiency virus and West Nile virus. Here, we investigate the effect of minocycline on Respiratory syncytial virus (RSV), a common respiratory virus th...

This report summarizes surveillance data reported to CDC for 2018 on nationally notifiable arboviruses. It excludes dengue, chikungunya, and Zika viruses because they are primarily nondomestic viruses typically acquired through travel. In 2018, 48 states and the District of Columbia (DC) reported 2,813 cases of domestic arboviral disease, including 2,647 (94%) WNV disease cases. Of the WNV disease cases, 1,658 (63%) were classified as neuroinvasive disease (e.g., meningitis, encephalitis, and acute flaccid paralysis), for a national incidence of 0.51 cases of WNV neuroinvasive disease per 100,000 population. Because arbovi...
