Distribution of CVPD is primarily in tropical and subtropical Asia. It has been reported in all citrus-growing regions in Asia except Japan. The disease has affected crops in China, Taiwan, India, Sri Lanka, Malaysia, Indonesia, Myanmar, Sri Lanka, the Philippines, Pakistan, Thailand, the Ryukyu Islands, Nepal, Réunion, Mauritius, and Afghanistan. Areas outside Asia have also reported the disease: Saudi Arabia, Brazil and, since 1998, Florida in the U.S..
This disease is distinguished by the common symptoms of yellowing of the veins and adjacent tissues; followed by yellowing or mottling of the entire leaf; followed by premature defoliation, dieback of twigs, decay of feeder rootlets and lateral roots, and decline in vigor; and followed by, ultimately, the death of the entire plant. Affected trees have stunted growth, bear multiple off-season flowers (most of which fall off), and produce small, irregularly-shaped fruit with a thick, pale peel that remains green at the bottom. Fruit from these trees tastes bitter.
