Investigation Underway

Investigations conducted by health authorities revealed the presence of dead chickens at the patient's residence. These chickens were reportedly cooked three days prior to the man falling ill.

Health authorities are actively investigating the source of the infection. They are also examining any suspected cases and individuals who had contact with the patient to prevent potential community transmission. Tamiflu (oseltamivir), an antiviral medication used to prevent the spread of bird flu, has been distributed to those who had direct contact with the patient.

Understanding H5N1 Avian Influenza

Avian influenza is caused by influenza viruses that primarily affect birds and poultry. In humans, symptoms can range from mild flu-like illness (fever, cough, sore throat, muscle aches) to severe respiratory illness. Eye infections and gastrointestinal symptoms have also been reported.

The incubation period for H5N1 typically ranges from 7 to 10 days. More virulent forms of the virus can lead to respiratory failure, multi-organ failure, and death.

Transmission and Risk Factors

Transmission to humans predominantly occurs through contact with infected live or dead birds and poultry, their droppings, or contaminated environments. Human-to-human transmission is generally inefficient.

Individuals with close contact to poultry are at higher risk of contracting avian influenza. Vulnerable populations, including the elderly, children, and those with chronic illnesses, face a greater risk of developing complications such as bronchitis and chest infections.
