By the end of 2021, 2.3.4.4b viruses were detected in North America, signifying further intercontinental spread. Here we show that the western movement of clade 2.3.4.4b was quickly followed by reassortment with viruses circulating in wild birds in North America, resulting in the acquisition of different combinations of ribonucleoprotein genes. These reassortant A(H5N1) viruses are genotypically and phenotypically diverse, with many causing severe disease with dramatic neurologic involvement in mammals. The proclivity of the current A(H5N1) 2.3.4.4b virus lineage to reassort and target the central nervous system warrants concerted planning to comba...

Getting infected with the canine influenza virus can leave as sick as a dog, if you are a dog. ... [+] (Photo: Getty) getty It’s already been a “ruff” flu season, in more ways than one. Humans across the U.S. have been dealing with a big surge in influenza cases. That’s after Covid-19 precautions over the past two Fall and Winters had seemingly put flu seasons on pause. And now those with paws, namely dogs, have been suffering from surges in the flu as well, specifically the dog flu. Veterinarians have been reporting outbreaks of such illnesses in various parts of the U.S. such as Texas and California, according to the following KRON news segment: Yeah, it’s been a dog-infect-dog world or at least country with many dogs transmitting a highly contagious H3N2 strain of the canine influenza virus (CIV) to each other. If you are human, this CIV strain is highly unlikely to infect you and get you sick. However, if you happen to have a tail, a strong urge to sniff other dogs’ butts, and a tendency to chase after sticks when someone throws them, catching this CIV strain can leave you as one sick puppy or one sick adult dog, depending on how old you happen to be. If you are not sure whether or not you are a dog, see your doctor or perhaps your veterinarian as soon as possible. It will be important to know to gauge of getting sick with the dog flu and for other aspects of your life. CIVs are similar to human influenza viruses in many ways. A dog sick with canine influenza can end u...

Buzz60, Buzz60 All eyes were on viruses like influenza and The Centers for Disease Control and Prevention last week reported an “There’s a much greater attention to identifying the cause of (infections) than we’ve ever had before,” said Dr. Rick Malley, an infectious disease specialist at Boston Children’s Hospital. He attributed that increased attention to the COVID-19 pandemic. “The importance of other viruses and the diseases they cause has come to the floor and that’s why I think you’re hearing more about this virus," he said. Here's everything to know about the respiratory virus that flew under everyone's radar this season, including symptoms, transmission and treatment. What is human metapneumovirus, hMPV? Human metapneumovirus, or hMPV, is an infection that affects the upper and respiratory tract, HMPV was first discovered in 2001 and belongs to the Pneumoviridae family, which also includes respiratory syncytial virus, the CDC said. New COVID variant: More: Is human metapneumovirus just a cold? What are hMPV symptoms? People with hMPV typically experience mild symptoms similar to a cold, The CDC says common symptoms include: • Cough • Fever • Nasal congestion • Shortness of breath Young children, older adults and those with weakened immune systems are at higher risk for developing more severe disease and can experience wheezing, difficulty breathing and asthma flare-ups. The American Lung Association said secondary infections – like bronchiolitis, bronchitis and pne...
