H3n2 test

When WHO officials choose the strains of influenza to include in the yearly flu vaccine, they choose two strains of influenza A (one variant of H1N1 and one variant of H3N2) and one or two strains of influenza B. Most flu vaccines contain three strains of influenza, but the quadrivalent vaccine and the A Word From Verywell Influenza is a difficult virus. It changes so frequently that it is hard to identify and treat—and even harder to develop the vaccine months in advance of flu season. H3N2 is one subtype of the influenza virus that often causes significant illness. When it is the dominant strain causing illness during a given year, those flu seasons are often more severe. It's important to take steps to protect yourself and your family from the flu each year, no matter which strain is making people sick.

• The H3N2 Test is a diagnostic test used to detect the presence of the H3N2 strain of the influenza virus. Anyone who is experiencing flu-like symptoms or is at a higher risk for complications from the flu should consider taking the test, including those with weakened immune systems, pregnant women, and elderly individuals.

Influenza H3N2 Test Influenza H3N2 virus testing is recommended for patients with influenza symptoms and helps medical professionals to make clinically informed decisions. Timely diagnosis is essential for people with suspected influenza to seek necessary medical management at the right time and avoid severe respiratory illness, which can lead to issues in their day-to-day activities. Also, ignoring influenza for a longer duration might prove to be fatal. Influenza, if detected at an early stage, it's possible to control the severity, controlling both your health and hospital bills. On the other hand, if influenza spreads to different body parts, it can lead to sepsis, pneumonia, and other conditions based on the type of influenza virus. So, if you observe cold, cough, and influenza, don’t ignore them. It’s time to book a test. We...

About the Virus Influenza A virus can cause infection in many mammalian and avian species and exists in multiple subtypes. CIV was first identified as a factor in canine respiratory disease in 2004. This virus is a genetic variant of the H3N8 equine influenza virus that gained the ability to infect dogs. The key change in the virus was the ability for transmission of the virus from dog to dog. The Asian H3N2 virus is derived from an avian strain that also gained the ability to infect dogs and be transmitted from dog to dog. As is the case with all influenza viruses, there is the opportunity for changes in the virus that could affect transmission rates and increase or decrease the ability of the virus to cause respiratory illness. Transmission and Symptoms CIV is transmitted by close contact with an infected dog, often in a restricted space such as an animal shelter, day care center, or boarding kennel. Casual contact is less likely to be a factor mainly due to the relatively low amount of virus shed by an infected dog. Virtually all dogs are susceptible regardless of age or breed. Influenza virus infection in dogs follows a similar pattern to infections in other species. The onset of clinical signs will be 2-3 days post infection. Peak of virus shed is 3-4 days post infection. Longer shedding times of up to 24 days have been identified in dogs infected with H3N2. Because of the differences in the time dogs may shed virus, the quarantine of 7 days is recommended for dogs wi...

What is canine influenza? Canine influenza virus (CIV) is primarily the result of two influenza strains: H3N8 from an equine origin; H3N2 from an avian source. Both strains were previously known to infect species other than dogs but can now infect and spread among dogs. The H3N8 equine influenza virus has been recognized in horses for more than 40 years. In 2004, the H3N8 influenza virus, or 'flu', appears to have 'jumped' from horses to dogs. The virus had mutated into a form known as the canine influenza virus (CIV), which is highly infective for dogs. Canine influenza has been detected in most states. At first, veterinarians thought the H3N8 canine flu would be pretty lethal. Fortunately, like the human flu virus, it kills very few healthy individuals with a mortality rate between 1-5%, and most deaths are in dogs with concurrent severe illnesses. For comparison, the 1918 Spanish flu had a mortality rate of only 2%. In March of 2015, a new strain of influenza was identified (H3N2) in Chicago during an outbreak of respiratory illness. Before this, the H3N2 strain of canine influenza had only been identified in Asia, after jumping from birds to dogs. After its initial detection, cases of H3N2 influenza were reported in many states and a few provinces in Canada. The strain was even detected in a group of shelter cats that were exposed to infected dogs. The University of Florida’s College of Veterinary Medicine reported a recent outbreak in May 2017. By mid-June, H3N2 infec...

Canine influenza is spread by dog-to-dog by aerosolization of two strains of the canine influenza virus (H3N8 and H3N2), as well as by contaminated objects and fomites. Most infections are mild with a persistent cough. Infected dogs can also be asymptomatic and shed virus. Treatment is supportive, with control measures consisting of routine infection control practices, hygiene measures, and vaccination. Etiology, Epidemiology, and Transmission of Canine Influenza Two strains of the canine influenza virus (CIV) have been identified, H3N8 and H3N2. The H3N8 strain was first identified in the USA in 2004 and had evolved from equine influenza. The H3N2 strain was identified as originating from Asia as an Asian avian influenza. An outbreak of H3N2 was identified in Chicago in 2015. Outbreaks are most common when dogs have not been vaccinated and are in close contact, eg, kennels, shelters, dog parks. CIV is transmitted dog to dog by aerosolization of the virus, via contaminated objects (eg, water bowls), and by other fomites (people). The incubation period is 1–5 days after exposure. Dogs are most contagious 2–4 days after infection and can be contagious before showing clinical signs. Approximately 20% of infected dogs remain asymptomatic but can still shed virus. Dogs should be considered contagious up to 4 weeks after exposure. Clinical Findings and Diagnosis of Canine Influenza Dogs of any breed or age can be affected. Most exposed dogs (approximately 80%) develop mild infec...

From July 12 to August 9, a total of 153 cases of H3N2v infections were reported in Indiana (120 cases), Ohio (31), Hawaii (one), and Illinois (one). Of the 138 reported cases for which demographic information was available, 128 (93%) occurred in persons aged <18 years, and 10 (7%) occurred in adults. The median age of patients was 7 years. Two persons were hospitalized as a result of their illness; no deaths occurred. The patient in Hawaii was exposed to swine on the job, and no additional cases were found in Hawaii. The 152 patients reported from Illinois, Indiana, and Ohio resided in 27 counties; all reported direct or indirect exposure to swine, the majority at agricultural fairs. H3N2v viruses can be detected by qualified U.S. public health laboratories using the CDC Flu rRT-PCR Dx Panel. Initially, if specimens tested positive for influenza A, H3, and pandemic influenza A markers and negative for H1 and pandemic H1 markers, they were reported as inconclusive until confirmed as influenza A (H3N2)v at the CDC laboratory. [ The CDC Flu rRT-PCR Dx Panel is available in public health laboratories but is not a point-of-care...

Influenza viruses belong to the family Orthomyxoviridae. Canine influenza is a Type A influenza virus and is further identified based on the composition of two specific proteins in the lipid outer layer of the capsid: hemagglutinin (HA) and neuraminidase (NA). At present, two strains of canine influenza virus have been identified in the United States: H3N8 and H3N2. Influenza viruses are able to quickly change and give rise to new strains that can infect different species. Both strains of canine influenza identified in the U.S. can be traced to influenza strains ...
