The World Health Organization assures that recent outbreaks of bird flu in cats have shown that better prepared Avoid worst-case scenario virus-to-virus spread with ‘experimental vaccine’ Humanity.

To make these vaccines, candidate virus have the antigenicity required to match circulating strains viral. “If the virus becomes highly transmissible from person to person, we need to have something Zhang Wenqing, director of the WHO Global Avian Influenza Program, said.

In fact, countries like the United States already they are working on a vaccine Laboratories including Sanofi and Moderna said in recent statements to Reuters that research and laboratories targeting bird flu have been able to face challenge if needed.

“The virus is particularly worrying Gebreyesus assured Pope Francis before visiting Pope Francis because it is known to be very dangerous to humans, although it has never been shown to spread easily from person to person. The content of the meeting was not disclosed. This is the second time they have met: the first was before the pandemic.

According to the World Health Organization, less than 900 cases Between 2003 and 2020, the number of human infections with bird flu increased, but 457 died.

Bird outbreaks reported in the Americas this year 17 passes Among mammals, there are five species. “Outbreaks detected in 15 countries in Latin America and the Caribbean are a situation never recorded before“, said Argentina’s latest epidemiological bulletin, which analyzed the situation in the country and globally.

Since the introduction of bird flu to the Americas in 2014, three human infections: The first in the United States on April 29, 2022; the second in Ecuador on January 9, 2023; the third in Chile on March 29, 2023.

It added that “in Argentina, following regional recommendations, early recognition contacts (exposure to sick or dead poultry in the event of an avian influenza outbreak) and their 10-day follow-up to identify possible suspected cases (cases that developed symptoms during the follow-up period)”.

This year has been confirmed in Argentina 328 people have been exposed to the virus, has been placed under surveillance.they signed up with each other 20 suspected cases, studied by the National Influenza Center.
