BANGKOK (Reuters) - Myanmar has reported what is believed to be the secretive country's first case of bird flu, while Afghanistan was checking on Monday to see if it is the latest country to be infected by the deadly disease.

Underscoring bird flu's rapid spread around the globe, Cameroon became the fourth African country to report an outbreak of bird flu on Sunday, joining Nigeria, Egypt and Niger, which have reported cases of the H5N1 flu virus in poultry.
