The distinction between the terms renminbi and yuan is similar to that between sterling and pound, which respectively refer to the British currency and its primary unit. One yuan is subdivided into 10 jiao (Chinese: è§; pinyin: jiÇo), and a jiao in turn is subdivided into 10 fen (Chinese: å; pinyin: fÄn).
Fleas are attracted to the warmth that the bodies of their hosts emit, vibrations and carbon dioxide, and they also like warm and carpeted environments where their hosts rest. These parasites feed on the blood of their hosts and can cause a number of conditions including skin infection and irritation, loss of hair and lethargy in their hosts.
Flea bites on humans are characterized by red blotchy skin. Many humans are unaware that fleas have bitten them. However, others may not be so lucky; they may be severely allergic to the flea bite saliva that can cause intense itching, red and swollen welts and bite marks in groups or clusters that may require a few weeks to heal.
