Mexico declared an end to the H7N3 bird flu virus outbreak in the western part of the country last week after reporting 68 days without a new case.
President Felipe Calderon announced on Wednesday that since the beginning of the outbreak in late June, more than 22 million hens were culled to contain the virus from spreading. The outbreak led to price increases of egg and chicken products throughout Mexico, Associated Press reports.
Calderon said that the outbreak caused significant damage to the country.
The United States and other countries exported eggs to Mexico during the outbreak in an effort to reduce prices, Associated Press reports.
Mexico first detected the outbreak in Jalisco on June 20. The outbreak was confined to Los Altos, the egg-producing region of Mexico, and was not found in any other parts of the country, Medical Daily reports.
As of August, the country had vaccinated 66 million birds with the goal of vaccinating 80 million birds overall against the H7N3 virus.
While the H7N3 virus occasionally infects humans in different parts of the world, it is not easily transmissible between humans. Other strains like H5N1 influenza can cause major human infections.
Since 2003, the World Health Organization has confirmed 607 human cases of bird flu and 358 deaths, Medical Daily reports.
