The patient has since been released from the hospital.<\/p>\n<p>The woman, who had no recent history of travel, began developing symptoms on September 14, <a href=\"https:\/\/www.paho.org\/sites\/default\/files\/2025-10\/2025-oct-15-phe-update-avian-influenza.pdf\" rel=\"nofollow noopener\" target=\"_blank\">according<\/a> to the Pan American Health Organization (PAHO). She was later admitted to a hospital in the country\u2019s capital.<\/p>\n<p>Her illness began with respiratory symptoms, including a runny nose and cough, which progressed to fever, painful swallowing, and later hemoptysis (coughing up blood) and chest pain. <\/p>\n<p>A sample collected on September 29 tested positive for unsubtypeable influenza A, and the presence of influenza A(H5) was confirmed by real-time RT-PCR the following day, PAHO said.

Bird droppings were also found in multiple areas, including a poorly sealed cistern that supplied water to all apartments in the building.<\/p>\n<p>Samples collected from the animals tested positive for influenza A(H5), while environmental samples are still being analyzed.<\/p>\n<p>Tests from 41 identified contacts of the patient were all negative for the virus, according to officials.<\/p>\n<p>It remains unclear which H5 subtype caused the infection. Mexico\u2019s first reported human case of avian influenza occurred in 2024 and involved the H5N2 strain, which led to the death of a 59-year-old man in the neighboring State of Mexico.<\/p>\n<p>Earlier this year, the country reported its first H5N1 case, a 3-year-old girl from a rural area in northern Mexico who died after severe complications. Genetic analysis identified the strain as Genotype D1.1.<\/p>\n<p>This genotype has also been detected in at least five human cases across North America, including the fatal case of a person in Louisiana in 2024, the first confirmed H5N1 death in the United States. It also caused severe illness in a teenager in Canada and in an adult in Wyoming in February.<\/p>\n<p class=\"has-text-align-center\"><a href=\"https:\/\/bnonews.com\/index.php\/human-cases-of-h5n1-bird-flu\" rel=\"nofollow noopener\" target=\"_blank\"><strong>LINK: A list of all human cases of H5N1 bird flu since 2021<\/strong><\/a><\/p>\n<p>The spread of H5N1 clade 2.3.4.4b and its multiple genotypes has raised concern among global health experts due to its wide geographic distribution and ability to infect both birds and mammals. <\/p>\n<p>Since 2022, at least 92 human infections with this clade have been reported worldwide, most linked to contact with infected poultry or dairy cattle.<\/p>\n","protected":false},"excerpt":{"rendered":"Mexico has reported a new human case of H5 avian influenza in a 23-year-old woman in Mexico City,&hellip;\n","protected":false},"author":3,"featured_media":318206,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[42340,46861,1322,159766,210,2222,159767,67,132,68],"class_list":{"0":"post-318205","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-health","8":"tag-bird-flu","9":"tag-disease-outbreaks","10":"tag-featured","11":"tag-h5n1-bird-flu","12":"tag-health","13":"tag-mexico","14":"tag-mexico-city-mexico","15":"tag-united-states","16":"tag-unitedstates","17":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115405774264130863","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/318205","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=318205"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/318205\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/318206"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=318205"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=318205"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=318205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
