Medicines for Bird flu

What it is

Bird flu (avian influenza) is a type of influenza (flu) that mainly affects birds. There are different strains, and some can cause serious illness and death in poultry and other birds. Importantly, bird flu does not usually infect people, and human cases are rare; when they do occur, they are usually the result of close contact with infected birds (alive or dead) or their droppings or environments, for example among people who work with poultry, or in areas where there are outbreaks in birds. Bird flu is not usually spread easily from person to person. However, some strains of bird flu can, rarely, infect people and cause illness that ranges from mild to severe, and certain strains have caused serious illness in the people they have infected — which is why bird flu is monitored closely by health and animal health authorities, and why there is concern about the possibility (currently uncommon) of strains changing in ways that could spread more easily. When bird flu does infect a person, the symptoms can be similar to those of ordinary flu, and may include a high temperature, aching muscles, headache, cough, and other flu-like symptoms; some strains can cause more severe illness, including breathing difficulties and complications. Because human bird flu is rare and usually related to close contact with infected birds, the main relevance for most people is prevention and awareness: avoiding contact with sick or dead birds, not touching bird droppings or surfaces contaminated by birds, and following public health advice, particularly during outbreaks or when travelling to areas with bird flu in birds; and good hygiene. People who work with poultry or in relevant settings follow specific precautions. If a person develops flu-like symptoms after close contact with birds in an area affected by bird flu, or if there is any concern, they should seek medical advice and mention the exposure. Bird flu in a person is a medical matter needing assessment and, where relevant, specific treatment (such as antiviral medicines) and public health measures. The key messages are that bird flu mainly affects birds and rarely infects people (usually from close contact with infected birds), that it can cause serious illness in the rare human cases, and that avoiding contact with sick or dead birds and following public health advice are the main preventive measures.

How it is treated

The approach to bird flu focuses on prevention and awareness for the general public (as human cases are rare and usually related to bird contact), and, for the rare human cases, medical assessment and treatment and public health measures. For most people, the relevance of bird flu is prevention: because human infection usually results from close contact with infected birds, the main measures are to avoid touching sick or dead birds, not to touch bird droppings or surfaces contaminated by birds, to wash hands well if there has been any contact, and to follow public health advice — particularly during outbreaks of bird flu in birds, or when travelling to areas where bird flu is present in birds (where advice may include avoiding live bird or poultry markets and contact with birds). Reporting dead wild birds (as advised by the relevant authorities) helps monitoring. People who work with poultry or in relevant settings, or who may have occupational exposure, follow specific precautions and guidance to protect themselves. If a person develops flu-like symptoms (such as a high temperature, aching muscles, cough, or feeling unwell) after close contact with birds in an area affected by bird flu, or if there is any relevant concern, they should seek medical advice and mention the exposure, as this is important for assessment; and anyone who is seriously unwell should seek urgent care. In the rare event of bird flu infecting a person, it is a medical matter managed with assessment, and, where relevant, specific treatment — antiviral medicines can be used and are more effective when started early, and supportive care is given for the illness (which can be severe with some strains) — along with public health measures to protect others and monitor the situation, coordinated by health authorities. Because bird flu is monitored closely for any changes that could affect its risk to people, public health authorities provide up-to-date advice, which it is worth following, particularly during outbreaks. The reassuring messages are that bird flu mainly affects birds and human cases are rare (usually from close contact with infected birds), that avoiding contact with sick or dead birds and following public health advice are the main preventive measures for the public, and that the rare human cases are managed with medical assessment, antiviral treatment where relevant, and public health measures; so awareness, avoiding bird contact, good hygiene, and following public health advice are the keys, and seeking medical advice for flu-like symptoms after relevant bird contact is important.
