Alert: Avian Influenza (Bird Flu) detected in SEABIRDS


PUBLIC-AWARENESS-ALERT-2.png


The highly pathogenic H5 strain of Avian Influenza has once again been detected in seabirds along the Western Cape coastline.

Seabirds affected thus far during the current outbreak: Hartlaub’s Gulls near Cape Town and Great White Pelicans near Malmesbury. These are the first detections of HPAI in wild birds in the Western Cape since April 2024 and the first reports of mass mortalities since late 2022.

What to look out for:
Infected birds may display neurological symptoms such as head tremors, twitching, and loss of coordination. They may appear dazed, unbalanced, or unusually tame. Affected birds may struggle to breathe, lose the ability to fly, or be seen flapping weakly on land or in shallow water.

What you can do:
If you come across any sick or dead seabirds on the beach:
  • Do not touch the birds.
  • Take a photo or short video, if possible.
  • Note the location, number of birds, and species (if known).
  • Report the sighting via WhatsApp with a location pin: 072 598 7117 or Email: penguin@dict.org.za
Your report will help us monitor and manage the spread of this virus.

What is being done:
Seabird colonies and rehabilitation centres across the coastline are actively monitoring the situation. All necessary biosecurity and containment protocols have been implemented. Cross-sector collaboration is aiding further disease surveillance and research.

Can the disease be treated?
Unfortunately, there is no cure or treatment for Avian Influenza in wild birds. Culling or disturbing habitats is not effective and may worsen the situation.

How it spreads:
Avian Influenza spreads through direct contact between infected and healthy birds. The virus is found in the secretions from the mouth, nose, and eyes, and in the droppings of infected birds.

Risk to humans and pets:
The risk to humans is very low, but precaution is essential:
  • If you spot a seabird in trouble, contact the rescue line for advice.
  • Do not handle dead birds.
  • Keep pets, especially dogs, away from carcasses.

Public urged to stay away from South Africa's coastline due to avian influenza outbreak

Weekend Argus Reporter | Published 54 minutes ago

Members of the public across South Africa are being urged to stay away from the coastline and avoid any contact with wildlife as a highly pathogenic strain of avian influenza continues to devastate wild bird populations along the Western Cape.
...
The scale of the crisis has prompted conservation bodies to scale up monitoring efforts, with experts warning that certain strains of the virus can cross the species barrier to infect humans. Although human infections remain rare, beachgoers are being advised to seek immediate medical advice if they develop flu-like symptoms following any potential exposure.

Dr Ashley Naidoo, the chief executive of CapeNature, stressed that seabirds act as critical indicators of the health of fragile marine and coastal ecosystems. He stated that by reporting suspected cases and rigorously following safety guidelines, the public can actively support conservation agencies in responding effectively while drastically reducing the health risks to both wildlife and people.
...
In alarming cases where multiple dead birds are discovered in close proximity, the public must immediately alert local stranding networks, the municipality, CapeNature, or SANParks by calling 083 236 2924 or emailing estuaries@capenature.co.za so that teams can be dispatched for safe bio-secure removal.
