December 22 2016 Outbreak Of Avian Lineage Influenza H7N2 Virus Infection Among Cats In Animal Shelter In New York City Was First Reported On December 9 2016. CDC Has Confirmed One Associated Human Infection In Person Who Had Close, Prolong Unprotected Exposure To Respiratory Secretions Of Infected, Sick Cats At Affected New York City Animal Shelter. Person Had Relatively Mild Illness And Is Recovering. No person-to-person of this virus has been identified at this time. CDC Believes Risk To Public Health From This Virus Is Low, But CDC And State And Local Public Health Authorities Are Conducting Routine Investigation To Try To Identify Any Other Human Infections Associated With Exposure To Ill Cats And Ensure That There Is No Person-to-person Spread Of This Virus Occurring. Avian influenza viruses have rarely been reported in but it is possible for cats to be infected with influenza, including avian influenza viruses. This is third human infection with avian influenza H7N2 ever reported in United States. Previously, there have been two human infections with similar H7N2 occurring in and 2003 pdf icon. One of infections was associated with exposure to infected poultry. Source Of Infection In Second Person Could Not Be Determine. Both people who become ill as result of H7N2 virus infection recover completely. Other human infections with influenza viruses have result mostly from prolonged close contact with infected birds. Finding avian influenza virus in unexpected host is always concerning and any human infection with non-human influenza virus is concerning as well. These incidents must be carefully investigated appropriate actions taken to ensure that there is no ongoing spread of this H7N2 virus among people. Animal and public health experts are working together to learn more about this situation and characteristics of this virus. More than 350 people with exposure to infected cats during this outbreak have been screened or tested infection with H7N2. Ill person report by New York City Department of Health and Mental Hygiene external icon is only human infection that has been detect. This, combined with past experience with rare avian influenza infections in humans via birds, suggests that risk of human infection is low, but likely increases with duration and intensity of exposure. It is possible additional human infections could be detected in association with this outbreak in cats. Risk Of Human Infection From Contact With H7N2-infected Person Also Is Thought To Be Low. Risk Posed By This Virus To Public Is Thought To Be Very Low At This Time. CDC is in close communication with human and animal health partners regarding this situation, providing situation-specific guidance relating to testing, clinical antiviral treatment and chemoprophylaxis, and infection control to support on-ground response, which is being lead by public health and Animal Health experts in New York City. Investigation Revealed That People Infected With H7N2 Travel On Domestic Flights While Potentially Infectious.

Virus

Most Common Way Cat Can Obtain H5N1 Is By Consuming Infected Bird. This has been studied in 2006 and 2007 cases in Germany and Austria where strains between cats and infected birds were different between species. Cat is able to then transfer viruses via respiratory tract and digestive tract to other cats. However, studies suggest that cats cannot transfer viruses to dog, vice versa, while sharing food bowl. Though there is no concrete evidence, there is potential link between transfer of virus between poultry, wild birds, and humans. Once cat is infect, after incubation period of 2 to 3 days, virus can be found in respiratory tissues, attached to type II pneumocytes and alveolar macrophages, as well as intestinal tissues. There have also been some cases where viruses have been found in brain and other systems in body. As of right now, H5N1 virus has not adapted to transfer in between mammals, but there is fear that this could occur.

Symptoms

To Editor: Recent reports of cats positive for H5N1 type influenza virus raise hypothesis that cats might have epidemiologic role in this disease. Experimental findings seem support this hypothesis. Experimentally infected cats might act as aberrant hosts, with symptoms and lesions developing and virus subsequently spreading to other cats. Experimental conditions under which this occurs, however, can rarely be observed for domestic wild cats. No spontaneous cases of transmission from cat to or cat to mammal have been report, and scientifically validated reports of spontaneous disease in cats are rare. Reports about cats with circulating virus antibodies are even more rare and occur in unusual epidemiologic situations. True susceptibility of cats to type influenza in field conditions thus remains to be elucidate. Base on assumption that partially susceptible animals should mount antibody response, we investigate possible presence of antibodies against nucleocapsid protein, common antigen of type influenza viruses, expressed by both avian and human strains, in feline serum samples stored at University of Milan and collected from 1999 to 2005. Only samples for which complete information regarding cat and its health status were included in study. Cats were grouped as healthy or sick on basis of clinical signs; complete clinicopathologic screening that included routine hematologic tests, clinical biochemical tests, and serum protein electrophoresis; serologic tests for feline immunodeficiency virus and feline leukemia virus infection, which are known to induce immunosuppression; and information regarding follow-up, including postmortem examination for dead animals. Specifically, 196 serum samples satisfied inclusion criteria in terms of information about sample cat and, according to above-mention Diagnostic approach, cats were group as reported in Table. Own cats were mainly living urban areas of Milan. By contrast, approximately half of free-roaming cats include from rescue shelters in rural areas northwest of Milan. Sixty samples from own cats and 51 samples from free-roaming cats were collected from September February, when seasonal human influenza peaks. Serologic tests for antibodies to type virus were performed with competitive ELISA to detect NPA antibodies. Negative control serum from specific-pathogen-free chickens and positive control serum specimens from different species were included in each plate to provide full range of controls. Serum samples were considered positive when absorbance value was reduced to at least 75 compared with 100 percentage for negative control wells. All cats were negative type influenza virus antibodies. ELISA We Use Has Been Validated In Several Species, Including Humans. Antibodies against NPA not major response to influenza infection but likely would have been detected if infections of cats were widespread. Thus, although no positive serum samples were used as positive controls, negative results are not likely false negatives.
