In contrast to most high-population-density tropical areas, cattle abound in India.
An organized program is more effective than an opportunistic program, and most importantly, high population coverage is a necessary factor for success.
Older people, especially those with chronic diseases, are the most high-risk population for severe illness and death [ 3– 5].
Guangdong not only has the most high-risk population of NPC, but also has a large number of smokers in China (about 16 million, based on the estimated smoking prevalence by Su et al).
First, it allows for population expansion into unoccupied patches which increases assortment/structure. Second, it reduces the negative effect of migration on population structure migration reduces population structure but is most effective at high population densities.
Interpretation of apparently negative data must be cautious, given the small size of most high-risk populations and the usual brevity of exposures.
In fact, even though the prevalence of adenomas in most high-risk populations is extremely high (as high as 20percentt in people under 50 and over 50percentt among people in their 70s [ 16], colorectal cancer is still a rare event.
Its most notable characteristics are the high population density and the fact that the Eastern Arc forests generally form habitat islands surrounded by drier and non-forested areas.
Because these areas are usually too small to contain self-seeding populations of most high dispersal marine species [7], networks of protected areas connected by dispersal are often required [8], [9], [10].
Most forests occur in areas of high population density.
Interestingly, most RTCs were grouped in the high population density rural districts.
