1. Bird Flu: Certain strains of influenza viruses (commonly known as "Bird Flu") that affect ducks can occasionally be transmitted to humans. Some strains of bird flu, such as H5N1 and H7N9, can cause severe respiratory illness in humans and even lead to death. While the risk of transmission from ducks to humans is generally low, people should avoid contact with sick or dead ducks and seek medical attention if they experience flu-like symptoms after exposure to ducks.
2. Duckweed Allergies: Some people may experience allergic reactions to duckweed, a type of small, floating plant that commonly grows in duck habitats. Duckweed allergies can cause symptoms such as sneezing, watery eyes, runny nose, and itchy skin. People with known allergies to duckweed should take precautions to avoid areas where duckweed is present.
3. Zoonoses: Ducks can harbor various microorganisms, including bacteria, viruses, and parasites, that can potentially cause diseases in humans if transmitted. However, most of these infections are rare and require close contact with ducks or their feces. Good hygiene practices, such as washing hands after handling ducks or being in their environment, can help reduce the risk of transmission.
Overall, while ducks are generally harmless to humans, it is recommended to maintain good hygiene practices and avoid contact with sick or dead ducks to minimize any potential health risks.
