What causes human reovirus?

What causes human reovirus?

Human volunteer studies have failed to demonstrate a clear cause-and-effect relationship between reoviruses and human illness. The method of transmission of reoviruses is unknown. However, because these viruses are recovered most frequently from the feces, primary spread seems most likely to be by the fecal-oral route.

What causes Orbivirus?

Many orbiviruses are transmitted by ticks or haematophagus insect vectors (Culicoides, mosquitoes and sand flies) and have a wide host range that includes cattle, goats and sheep, wild ruminants, equids, camelids, marsupials, sloths, bats, birds, large canine and feline carnivores, and humans….

What does reovirus stand for?

Reoviruses can affect the gastrointestinal system (such as rotaviruses) and respiratory tract. The name “reo-” is an acronym for “respiratory enteric orphan” viruses. The term “orphan virus” refers to the fact that some of these viruses have been observed not associated with any known disease.

How is reovirus treated?

No specific treatment or prevention measures have been recommended for reovirus infections in humans because of the lack of definitive association with disease.

What are the symptoms of reovirus?

Infants and young children most commonly have fever, vomiting, diarrhea, and (occasionally) dehydration. Vomiting, usually short-lived, can occur before or after the onset of diarrhea. Symptoms of an apparent respiratory infection may be present.

How common is reovirus?

Reovirus infections are quite common in humans, although they tend to be mild or subclinical. The extent of their role as agents of illness in humans is unclear. Four human orbiviruses or coltiviruses have been associated with human disease.

What is Chobar Gorge virus?

The species Chobar Gorge virus includes two serotypes/strains: Chobar Gorge virus (CGV) isolated in 1970 from Ornithodoros spp. ticks in Nepal; and Fomede virus (FV) isolated in 1978 from a bat in Kindia, Guinea. There is serological evidence for infection of cattle, horses, sheep, buffalo and humans [9].

What diseases are caused by arbovirus?

Examples include California encephalitis, Chikungunya, dengue, Eastern equine encephalitis, Powassan, St. Louis encephalitis, West Nile, Yellow Fever, and Zika.

Can humans get reovirus?

Reovirus infections occur often in humans, but most are mild or subclinical. The virus is detected efficiently in feces. It may also be recovered from nasal or pharyngeal secretions, urine, blood, cerebrospinal fluid, and various organs obtained at autopsy.

Can humans get reovirus from dogs?

Follow your veterinarian’s advice and avoid exposing any other healthy pets to your dog. Some reoviruses are contagious, even infect children and infants at times.

How do you test for reovirus?

Diagnosis is commonly accomplished via serology (ELISA, MFIA™, IFA), but may also be performed via PCR. Natural infection with reovirus is not proven to be specifically linked to interference with research.
