H5N1 is currently a ZOONOTIC OUTBREAK, NOT A PANDEMIC !!!
For over two years, we have been raising concerns about the transmission of this virus from birds to mammals, and subsequently to humans.
At this time, H5N1 remains a zoonotic outbreak, which is characterized by ...
2) ...a sudden rise in disease cases from animals to humans within a specific area or population.
Even if we are at stage 3 in the virus's progression, (as I indicated in my last thread 👇), for H5N1 to be classified as a pandemic ...
SARS-COV-2 POPULATION IMMUNITY: EPITOPES, EPITOPES and EPITOPES !
An epitope is a small part of a molecule (like a protein) that the immune system recognizes and binds to, triggering a response. journals.plos.org/plospathogens/…
2) This study examined how the antibody response targets different parts of the SARS-CoV-2 spike protein, depending on a person's prior infection and vaccination history. The researchers created a panel of mutant spike proteins to map the key epitopes ...
3) ...recognized by neutralizing antibodies. They found that primary infections with different variants elicited distinct antibody targeting patterns, highlighting the antigenic diversity between variants.
Time is of the essence: effectiveness of dairy farm control of H5N1 is limited by fast spread
Weekly bulk milk testing for H5N1 is often too late; better surveillance and focus on biosecurity are needed for effective intervention. buff.ly/3YWGRCy
2) Very interesting data/figures

3) Fig. 2 : Surveillance and control strategies require knowledge of both the basic repro- duction number and the intrinsic growth rate.
2) Avian influenza, or "bird flu," is a major public health concern worldwide. The H5N1 strain is particularly dangerous, with high rates of transmission and death. While it mainly infects birds, this virus can also spread to humans, leading to severe illness.
3) Diagnosing avian flu requires specialized testing of respiratory samples. Early treatment with antiviral medications like oseltamivir is essential to manage the infection. Preventing exposure by avoiding contact with infected birds and animals is a key prevention strategy.
2) The study examined over 1,000 hospitalized COVID-19 patients and found that many had reactivation of viruses they were already carrying, like Epstein-Barr virus and cytomegalovirus.
3) These reactivated viruses were linked to more severe COVID-19 symptoms and worse outcomes, including higher risk of death.
The researchers also saw that the reactivated viruses triggered specific immune responses, like increased inflammation and changes in gene activity.
AVIAN INFLUENZA A (H5N1, H5N6, H9N2 and H7N9) viruses in China
Diverse group of viruses, each influenced by its unique ecological and social factors, for example density of pig or human population emerged as common significant predictors for H5N1 frontiersin.org/journals/publi…
2) This study examined the patterns and risk factors for human infections with different strains of avian influenza viruses (H5N1, H5N6, H9N2, H7N9) in China from 2011-2024.
The researchers found that the geographic distribution of cases varied by virus type.
3) H5N1 and H5N6 infections were mostly concentrated in eastern and southwestern China, while H9N2 and H7N9 were more widely spread across the country. The timing of cases also differed - H5N1 showed seasonal patterns, while H5N6 and H9N2 had sporadic cases throughout the year.
