How Bird Flu Is Manifested In Humans

Professor Peter Openshaw, head of respiratory infections at National Heart and Lung Institute, Imperial College, London answered some questions regarding bird flu symptoms.

Which are the symptoms of the bird flu in humans? The symptoms of bird flu in humans are similar with those of an ordinary flu with fever, cough, muscle aches and short breath. Pay attention if your temperature goes up to 38 degrees, it might be bird flu but, if the temperature is lower it might be only a common flu. In almost half of the cases bird flu seems to be like an abdominal flu with diarrhea, abdominal pain, vomiting. So, to be sure you should perform some tests, if you hadn?t been in contact with sick poultry then you don?t need to worry for sure it?s only an ordinary flu.

How to be sure that is bird flu and not any other common flu? After the exposure in 3-7 days the symptoms develop. By the time patients get to the hospital it is too late to follow a treatment with antiviral agents.

How quickly is manifested the disease ? Bird flu should be treated within two days after developing fever of 38 degrees, that?s why is so important to measure your temperature. Severe symptoms that lead to death: The organ which is most affected is the lung and that?s why most people die. Some are developing kidney problems and more than a half bone marrow deficiency, so the bone is not producing cells to deal with the infection so the body is overwhelmed.

What is to be done if someone suspects that he is infected? It is very important to get close to a medical facility that can provide artificial ventilation if necessary and antiviral drugs, especially in the early stages of the disease. Next, the treatment is supportive and needs to overcome the kidney or lung failure and the spreading of the virus. The only subtype that can cause severe illness to people is Influenza A /H5N1 virus, initially it affects chickens, ducks and other birds by the process of mutation they can become highly pathogenic. Because highly pathogenic viruses can survive for long periods in tissue, water and in the environment, especially when temperatures are low is transmitted very easily in chickens and other birds through direct contact with feces and secretions from infected birds, eggs, feed, water, cages equipment, vehicles and clothing. Public health authorities monitor human illnesses associated with avian influenza. In Hong-Kong occured for the first time infection both in humans and poultry and were killed about 1.5 million chickens. In China and Hong-Kong avian influenza A (H9N2) virus infection affected two children who recovered. The source was unknown, but suspected the poultry.
