? ? ? ? ? ?Controlling the Growing TB Crisis in
China{{/B}}
? ?China needs to take urgent action to address a
"vicious cycle" of poverty and tuberculosis (TB) affecting a considerable number
of Chinese people, especially in underdeveloped areas, the World Health
Organization said on Monday.
? ?The Chinese government needs to
take "immediate necessary action" to control the spread of TB, which is
"threatening the future of its 1.3 billion people", WHO said in a report
released at the start of a three-day meeting to discuss TB in the Western
Pacific region.
? ?Poor living conditions and health care in rural
China mean the TB infection rate is nearly three times higher than in urban
areas, the report said. There are some factors that make the rural TB burden
heavier such as insufficient funds for local health programs and increased
charges for medical care, it said.
? ?"This has uniformly produced
a negative impact on TB diagnosis and treatment, especially in areas without
specific funding targeted towards TB-related services," it said. The report,
which is meant to foreshadow the seriousness of the TB crisis in China, suggests
that China adopt a two-year program to control the disease.
? ?The
government should fund free TB drugs and diagnosis, health promotion and
training, and supervised treatment programs at all levels, it said. "TB control
should be considered as a key development issue and poverty reduction strategy,"
WHO Western Pacific regional director Dr. Shigeru Omi said at the opening of the
meeting in Beijing.
? ?A World Bank-funded project in 13 of China’s
31 provinces produced "astonishing" results, reducing the incidence of TB by 38
per cent in less than 10 years, WHO said. "This tremendous achievement tells us
that the regional target of reducing the prevalence of TB by half in 10 years,
though ambitious, is achievable," Omi said.
? ?But TB "remains a
relentless killer in the Western Pacific region", claiming around 1,000 lives
daily in the region -- more than half of them in China, a WHO press statement
said. "The worsening burden of TB has resulted in a great human tragedy and has
had a profound impact on economic development in several countries in the
region," the statement said. |
The ambitious target of WHO in reducing the incidence of TB in the Western Pacific region is to
A:reduce the incidence of TB by 38% in less than ten years in the region. B:reduce the incidence of TB by 50% in ten years in the region. C:eliminate TB in ten years in the region. D:fund a project in 13 of China’s 31 provinces to fight ＴＢ.
