First US death from H5N1 avian flu sparks serious concerns
A 65-year-old man has died in Louisiana, marking the first fatal case of H5N1 avian flu in the USA. Scientists warn that the virus is "quite dangerous."
Louisiana has reported this first fatal case. The man, who was hospitalized in December in serious condition, had contracted the virus through contact with domestic and wild birds. He had underlying health conditions that may have affected the severity of his illness.
Avian flu (H5N1) is considered a potential pandemic threat. While human infections are rare, they are fatal in over 50% of cases. The World Health Organization (WHO) lists the virus as one of the most dangerous pathogens that could potentially trigger another pandemic. Currently, avian flu is spreading among various animal species, and experts warn it could mutate to spread among humans.
The investigation found no other cases of H5N1 infection in humans nor any evidence of human-to-human transmission. In the USA, more than 65 people have contracted avian flu, primarily through contact with infected livestock, especially poultry. WHO reports that out of over 950 cases worldwide, approximately 50% have resulted in death.
Data from over 20 years shows it is quite a dangerous virus. I don't expect future infections to be mild," said Jennifer Nuzzo from Brown University.
Nuzzo warns that the virus is dangerous and unpredictable in terms of who will experience severe illness. She emphasizes that the death in Louisiana, influenced by the patient's underlying conditions, should not be underestimated.
Limited virus transmission
So far, the transmission of the H5N1 virus among humans is limited, but its ability to infect various species increases the risk of wider spread. Scientists highlight the need for monitoring and quick response to potential threats. It is recommended to avoid contact with wild birds, poultry, and rodents, and to wash hands after contact with potentially contaminated items. Pets can also become infected, particularly through consuming raw meat or milk.
Preventive actions and public education are crucial in preventing a pandemic associated with avian flu. The global mobility of people and goods poses a risk of spreading the virus. Public authorities are working to reduce human contact with infected animals and conduct research on virus mutations, which may help control its spread.
