Bird flu: Symptoms in humans and prevention tips
"In humans, bird flu causes respiratory symptoms like cough, cold, fever and breathing difficulty," says Dr Laxman Jessani, Consultant, Infectious Diseases, Apollo Hospitals, Navi Mumbai.
"In severe cases, the virus can cause Acute Respiratory Distress Syndrome and may even lead accumulation of fluids in the lungs. It can be fatal in these cases," he adds. However, the virus does not easily spread to humans. People coming in close contact infected birds, dead or alive, have contracted H5N1 bird flu.
The World Health Organization has mentioned that the virus does not usually spread from person to person. It added that there's no evidence that the disease can spread to people through properly prepared and cooked poultry food. This is because the virus is sensitive to heat and is likely to die in cooking temperatures.
"You can eat thoroughly cooked, boiled, roasted or baked meat. Avoid having it in the form used in salads," says Dr Jessani.
