First human death from avian flu reported in Mexico

"As long as the human being cannot transmit it to other humans, it is not problematic," says a spokesperson for the Spanish Society of Infectious Diseases.

The World Health Organization (WHO) reported this Wednesday the first death from AH5N2 bird flu in the world, which would have been detected in a laboratory in Mexico.

According to the information, the victim would be a 59-year-old man who died on April 24 and the source of exposure to the virus that has been reported in poultry in Mexico is unknown.

“This is the first laboratory-confirmed human case of influenza A(H5N2) virus infection reported globally, and the first A(H5) virus infection reported in a person in Mexico,” the WHO warned in its website, cited by EFE.

According to the agency, the man, who lived in the central State of Mexico, had no history of exposure to poultry or other animals.

He explained that, on May 23, Mexican health authorities informed the WHO about the confirmed case of human infection with the avian influenza A(H5N2) virus.

According to family members, the patient had already been bedridden due to other health conditions that afflicted him, but on May 17 he developed fever, difficulty breathing, diarrhea, nausea and general malaise.

On April 24, he sought medical attention and entered the 'Ismael Cosío Villegas' National Institute of Respiratory Diseases (INER), where “he died that same day due to complications from his condition.”

The case is reported after the H5N1 bird flu virus has spread in recent weeks in dairy cows in the United States, a country neighboring Mexico.

And although three human cases have been recorded in that country so far this year, US health authorities have clarified that none of the infections are related to the outbreak of the virus in cows.

In late March, it emerged that dairy cows in Texas and Kansas were infected with bird flu, and days later, USDA officials confirmed cases within a herd of Michigan dairy cows that They had recently been in contact with specimens from Texas.

The virus, identified as H5N1, is a subtype of avian flu that is highly contagious among birds.

The Ministry of Health (SSa) of the Mexican Government reported this Wednesday that “there is no risk of contagion for the population with the detection of the first human case of low pathogenicity avian influenza A (H5N2) in Mexico, since there is no source identified infection.”

In Mexico, on April 5, the National Agri-Food Health, Safety and Quality Service (Senasica) declared the country a zone free of AH5N2 avian flu and said that the virus had been absent for more than 25 years, since the last case corroborated in commercial production dated June 5, 1995.

A new virus in humans

“This does not make it more likely that the virus will be transmitted between humans. "It is an isolated case," said the spokesperson for the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), warning that these are new viruses in humans, so despite being an isolated case and while humans cannot transmitting to other humans is not problematic”, without ruling out the alert regarding a possible new pandemic.

And this transmission between humans, which now does not exist, would be a fundamental step “for the emergence of a new pandemic,” the doctor noted, something that for the moment is contained in the narrow surveillance systems.

They are isolated, specific cases, but, he warned, “the moment human transmission appears, a pandemic immediately occurs because they are 2% new viruses for humans,” as happened with the SARS-CoV-XNUMX coronavirus since they do not there is a prior immunity.

The vice president for health, education, science and technology of Venezuela, Gabriela Jiménez, commented on her social networks that the two strains of influenza A virus have mainly affected wild and farmed birds, infecting flocks throughout the country. world. About 1996 human cases of H900N5 have been reported since 1, and about half of the people known to be infected have died.
