Transmission electron micrograph of the Sin Nombre virus, the virus responsible for the outbreak. The spherical particles are virus bodies (virions). The 1993 Four Corners hantavirus outbreak was a disease outbreak caused by a hantavirus that occurred in the Four Corners region of the US states in Arizona, Colorado, and New Mexico.
Hantavirus pulmonary syndrome (HPS) is one of two potentially fatal syndromes of zoonotic origin caused by species of hantavirus. [2] These include Black Creek Canal virus (BCCV), New York orthohantavirus (NYV), Monongahela virus (MGLV), Sin Nombre orthohantavirus (SNV), and certain other members of hantavirus genera that are native to the United States and Canada.
Rodent mites are capable of surviving for long periods without feeding and travelling long distances when seeking hosts. [4] Cases have been reported in homes, libraries, [5] hospitals [6] and care homes. [7] A similar condition, known as gamasoidosis, is caused by avian mites. [8]
These viruses are transmitted primarily through contact with rodents, such as rats and mice. Exposure to their urine, droppings, or saliva can increase the risk of infection. While less common, bites or scratches from infected rodents can also lead to transmission. [11] The manner of transmission is the same for both diseases caused by ...
The coxsackieviruses subsequently were found to cause a variety of infections, including epidemic pleurodynia (Bornholm disease), and were subdivided into groups A and B based on their pathology in newborn mice. (Coxsackie A virus causes paralysis and death of the mice, with extensive skeletal muscle necrosis; Coxsackie B causes less severe ...
Symptoms in humans are due to allergic responses or systematic toxaemia caused by waste products of the tapeworm. Light infections are usually symptomless, whereas infection with more than 2000 worms can cause enteritis , abdominal pain, diarrhea , loss of appetite, restlessness, irritability, restless sleep, and anal and nasal pruritus.
Mice contaminate food, chew up everything in sight, and spread illnesses through their urine, saliva, and droppings, says Sheldon Owen, a wildlife extension specialist at West Virginia University.
Rat-bite fever (RBF) is an acute, febrile human illness caused by bacteria transmitted by rodents, in most cases, which is passed from rodent to human by the rodent's urine or mucous secretions. Alternative names for rat-bite fever include streptobacillary fever, streptobacillosis, spirillary fever, bogger, and epidemic arthritic erythema.
