Bird flu (avian influenza)

Other names: Flu, avian

Bird Flu, also known as avian influenza, is a viral infection that primarily affects birds but can occasionally infect humans. The two main strains that have caused human infections are H5N1 and H7N9. Outbreaks of bird flu have been reported in various parts of the world, with most cases linked to close contact with infected birds.

SYMPTOMS

Symptoms of bird flu in humans are similar to those of regular influenza and may include cough, fever, sore throat, muscle aches, headache, and shortness of breath. Some individuals may also experience gastrointestinal symptoms like nausea, vomiting, or diarrhea.

CAUSES

Bird flu is naturally present in wild birds and can spread to domestic poultry through contact with infected birds' bodily fluids. Consumption of undercooked poultry products or eggs from infected birds can also transmit the virus to humans.

RISK FACTORS

The primary risk factor for bird flu is direct contact with sick birds or contaminated surfaces. While human-to-human transmission is rare, it poses a significant concern for potential global outbreaks if the virus mutates to become more easily transmissible among people.

COMPLICATIONS

Severe cases of bird flu can lead to complications such as pneumonia, respiratory failure, kidney dysfunction, and even death. However, the overall number of human fatalities from bird flu remains relatively low compared to seasonal influenza.

TREATMENT

Antiviral medications like oseltamivir (Tamiflu) are commonly used to treat bird flu infections. Early initiation of treatment is crucial for better outcomes. There are ongoing efforts to develop vaccines specifically targeting different strains of the virus.

Prevention

Practicing good hygiene, avoiding contact with sick birds, thoroughly cooking poultry products, and getting vaccinated (when available) are essential preventive measures against bird flu.
