The first outbreak of the bird flu (H5N1) in humans occurred in 1997. Eighteen people in Hong Kong were infected; 6 died. In an effort to stop the spread of the virus, the Chinese government responded by destroying the poultry population—1.5 million birds. Since 1997, the bird flu has infected people in over 15 countries in Asia, Europe, the Near East, the Pacific, and Africa, and it remains a highly contagious and deadly virus among birds. There is a fear that the bird flu could mutate and spread more easily to humans. The fear of a pandemic is further heightened by the fact that migratory birds can continue to spread the virus to other countries. There are also additional bird flu viruses now, such as H7N9.
If you have plans to travel abroad, then you should find out the facts.
The bird flu is caused by the type A strain of the influenza virus. In the wild, influenza A is easily spread among birds, but they usually do not get sick from the virus. Domestic birds, like chickens, are more susceptible, though. Among poultry populations, a highly dangerous form of the flu can cause severe sickness and death within 48 hours.
While the bird flu has infected tens of millions of poultry, H5N1 remains rare among humans. Those at the greatest risk of infection are people who have direct contact with sick or dead birds or with surfaces contaminated by the virus. While there is the potential for the virus to mutate and become more contagious, at this time, the bird flu does not spread easily from birds to people, nor does it spread easily between people.
For those who get the bird flu, symptoms range from mild to severe. Bird flu can cause fever, chills, cough, sore throat, diarrhea, and vomiting. In severe cases, H5N1 (and H7N9) can quickly progress to respiratory distress, pneumonia, organ failure, and death.
H5N1 is treated with antiviral medications; however, the infection is resistant to some of them. There is a vaccine to protect against a strain of the virus, but it is not currently available to the public. The vaccine was purchased by the government for the Strategic National Stockpile. Health officials will distribute the vaccine if a crisis arises.
There are periodic reports of cases of the bird flu. These cases do not mean you have to change your travel plans. When you make your arrangements, check the Centers for Disease Control and Prevention (CDC) Travel website for updated information. Check for updates regularly and take any action recommended by the country you are visiting.
Before you travel, plan ahead for an outbreak. The local government, in an effort to contain the virus, is likely to place restrictions on where people can go. You can be prepared by having a supply of necessities, such as canned food, water, and medications. If you can, find out where to go for medical care.
To reduce your chance of being infected with the bird flu, follow these guidelines from the CDC and the WHO:
In addition to these tips, make sure that all of your immunizations are up-to-date before you travel. Keep in mind that none of these immunizations will protect you from bird flu. Also, research what medical facilities exist and what resources are available. Use the US Department of State website for a list of all of the US embassies. From there, you can find information on foreign hospitals and doctors.
If you do get sick while abroad, contact the US consulate in the country you are in and an officer can help you locate medical care. In addition, follow these tips:
