A person in Louisiana has been hospitalized with H5N1bird flu , mark the United States ' first knockout case of the sickness .
In astatement secrete Wednesday(Dec . 18 ) , the Centers for Disease Control and Prevention ( CDC ) mention that , in total , 61 people in the U.S. have had a confirmed case of H5N1 this year . Of the old 60 cases,37 caught the virus from dairy cows , 21 from fowl , and two from unknown informant . The presumptive case wasfirst announced by LouisianaFriday and was confirm by CDC tests the same Clarence Day .
The patient likely caught H5N1 from a backyard flock of birds, officials say.
Notably , however , the virus in the Louisiana patient differs genetically from the computer virus spreading among dairy farm cows .
The pains circulating in dairy farm cows is known as the " B3.13 genetic constitution , " while the one that sickened the Louisiana affected role is the " D1.1 genotype . " The latter is do it to be circulating among uncivilized birds and fowl in the United States and Canada . Recently , D1.1 infectedpoultry worker in Washington land , who had modest slip , and ateen in British Columbia , who had a terrible casing that required intensive precaution .
The precise source of the stripling ’s infection has not been distinguish , but genetic testing suggested the computer virus is genetically like to a strain detected in wild bird in the Fraser Valley area in southwestern British Columbia .

The source of the Louisiana patient role ’s infection is also unknown , but birds are suspected .
" While an investigation into the source of the infection in Louisiana is ongoing , it has been determined that the affected role had picture to sick and beat birds in backyard flocks , " the CDC note .

The CDC added that see a hard case of H5N1 is not wholly unexpected . Historically , of the over900 people known to have caught the virus worldwide , more than half have died . But these death have affect the great unwashed outside the U.S. and have ask H5N1 strains with unlike genetic traitsthat might facilitate explain their virulency .
The CDC still think the risk of H5N1 infection among the oecumenical populace to be down in the mouth . That ’s partly because there is still no evidence of the computer virus spreading from one person to another .
A recent study — albeit one thatfocused on an H5N1 strain from a moo-cow — suggested that the virus may not need to mutate very much to start circulate between citizenry . So functionary will continue to supervise the virus ’s spread from all animals while also encouraging masses at the highest risk of exposure to take guard .

Dr. Demetre Daskalakis , director of the CDC ’s National Center for Immunization and Respiratory Diseases , tell reporters at a news conference that the Louisiana patient was hospitalized with flu symptoms , accord tothe University of Minnesota ’s Center for Infectious Disease Research & Policy .
Daskalakis deferred to Louisiana health officials to share further detail about the patient , should they pick out . The wellness section has not yet share specifics of the patient ’s circumstance due to secrecy concerns and the fact that the investigating into the case is on-going .
