Confirmed first death of human infected by the H5N5 strain of avian flu
No additional cases have been detected in people related to the victim and the situation is being monitored to prevent outbreaks
Washington state health officials confirmed the death of the first human infected with the H5N5 strain of avian flu. The victim was an elderly adult with pre-existing health conditions and had been in contact with domestic birds at their home. “This individual had a flock of mixed domestic birds in their backyard,” the Washington State Department of Health said, in a statement reported by CNN. Authorities have chosen not to release further details out of respect for the family's privacy. Several types of avian flu strains are known to exist, although the 70 human cases reported in the United States during the last year and a half were all of H5N1, according to the Centers for Disease Control and Prevention (CDC). H5N5 strain of avian flu: The H5N5 strain, previously identified in animals but never in humans, joins the list of avian flu strains that have affected various species. Human-to-human transmission remains unproven.
Despite the severity of the case, health officials assure that the risk to the general population remains low.
No additional cases have been detected in people connected to the victim, and the situation is being monitored to prevent future outbreaks.
Evolution of Avian Influenza in Mammals
Since 2024, avian influenza has begun to affect mammals, expanding its areas of impact.
Most human cases have occurred after contact with infected birds, and while mild symptoms have been reported, some infections have been more severe, including the death of patients with pre-existing conditions.
The Washington State Department of Health recommends influenza vaccination for anyone who comes into contact with domestic or wild birds. Although the regular flu vaccine does not protect against avian influenza,Yes, it reduces the likelihood of a person contracting both viruses simultaneously and causing a mutation of the avian influenza virus.
Are there specific symptoms of the H5N5 strain in humans?
The H5N5 strain of avian influenza in humans presents symptoms similar to other avian influenza infections, although the available information is still limited because its reporting in humans is very recent.
Specific symptoms observed and reported include cough, runny nose, sore throat, chills, conjunctivitis, and eye infection. General symptoms such as fever, headache, and malaise are also mentioned.
This strain can cause irritation and redness of the eyes, called conjunctivitis, which has been a predominant symptom in recent cases of H5 influenza virus infections. In addition, some symptoms can be mild, such as moderate fever, nasal congestion, muscle aches, and fatigue, or they can progress to more severe symptoms that affect breathing and the person's overall condition.
Monitoring and Control
Health authorities are taking several measures to monitor and control the avian influenza outbreak in humans. These include:
These actions aim to detect new cases early, prevent human-to-human spread, and contain the outbreak in animals to prevent future infections.
