Translation:Bird flu is a dangerous plague because it spreads very fast.
okay, now i'm just starting to get angry! tonight it's not accepting ANYTHING no matter how close. I put "the bird flu is a dangerous plague because it spreads very fast." (even though I really wanted to change it to quickly, but it wouldn't accept it merely because of the "the," which their own rules say is to be "the" if it doesn't have a "mot"!!!
'Bird flu' is not a 'plague'. It's a 'disease'. Plague is an infectious disease caused by the bacterium Yersinia pestis. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. In the bubonic form there is also swelling of lymph nodes, while in the septicemic form tissues may turn black and die, and in the pneumonic form shortness of breath, cough and chest pain may occur.
