The Alzheimer's epidemic
The global price for treating Alzheimer’s and other dementias was an estimated $604 billion in 2010.
70% of this was paid in North America and Western Europe.
It is estimated that the amount will exceed $1 trillion annually by 2030, with 65.7 million people affected, up from 35.6 million in 2010.

Seven in 10 Mexican adults are overweight or obese.
Nearly half of all Brazilians, Russians and South Africans are overweight or obese.
Severely obese people die 8-10 years sooner than those of normal weight.
Malaria still bites
In 2008, there were 247 million cases of malaria and nearly one million deaths.
In Africa a child dies every 45 seconds of Malaria; the disease accounts for 20% of all childhood deaths.
Malaria can decrease gross domestic product by as much as 1.3% in countries with high disease rates.
In some heavy-burden countries, the disease accounts for up to 40% of public health expenditures; 30% to 50% of inpatient hospital admissions; and up to 60% of outpatient health clinic visits.
Diabetes on the rise
Diabetes affects an estimated 21 million people in the U.S. — more than six million of these are unaware they have the disease.
The International Diabetes Federation estimates that there are 246 million adults with diabetes.
The Western Pacific region and Europe have the highest number of people with diabetes, approximately 67 and 53 million, respectively. The highest prevalence rates are found in North America (9.2%) and Europe (8.4%).
The five countries with the largest numbers of people with diabetes are India, China, the United States, Russia and Germany. The five countries with the highest prevalence rates are Nauru, United Arab Emirates, Saudi Arabia, Bahrain and Kuwait.
HIV/AIDS: the forgotten epidemic
In Sub-Saharan Africa 12 million children have been orphaned by Aids, and by the end of 2010 it is anticipated that this number will have risen to 43 million.
2.7 million people were newly infected with HIV worldwide in 2008.
There were 1.37 million new cases of tuberculosis worldwide among HIV-infected people in 2008.
Two million people died of AIDS-related illnesses worldwide in 2008.
5.25 million HIV-positive people had access to antiretroviral therapy (ART) in low- and middle-income countries in 2009.
67% of all people living with HIV are in sub-Saharan Africa.
1.8 million children were living with HIV in sub-Saharan Africa at the end of 2008.
Smoking's dark shadow
In England in 2008/09 an estimated 462,900 hospital admissions of adults aged 35 and over were attributable to smoking. This accounts for 5% of all hospital admissions in this age group.
In England in 2009 an estimated 81,400 deaths of adults aged 35 and over were attributable to smoking. This accounts for 18% of all deaths in this age group.
Over half of China’s men smoke (about 2.4% of women do); China’s 301 million adult smokers usually started before the age of 20.
Mental health questions
Around 20% of the world's children and adolescents are estimated to have mental disorders or problems, with similar types of disorders being reported across cultures.
Most low- and middle-income countries have only one child psychiatrist for every 1 to 4 million people.
On average about 800,000 people commit suicide every year, 86% of them in low- and middle-income countries.
More than half of the people who kill themselves are aged between 15 and 44.
The highest suicide rates are found among men in Eastern European countries.
Mental disorders are one of the most prominent and treatable causes of suicide.
Someone in the world is newly infected with TB bacilli every second.
Overall, one-third of the world's population is currently infected with the TB bacillus.
5-10% of people who are infected with TB bacilli (but who are not infected with HIV) become sick or infectious at some time during their life. People with HIV and TB infection are much more likely to develop TB.
The largest number of new TB cases in 2008 occurred in South-East Asia, which accounted for 34% of incident cases globally. But, the estimated incidence rate in sub-Saharan Africa is nearly twice that of South-East Asia with over 350 cases per 100,000 population.
Food for thought
In India, in the past five decades, rates of coronary disease among the urban population have risen from 4% to 11%. The World Health Organisation estimates that 60% of the world’s cardiac patients will be Indians by 2010.
WHO estimates that in the period 2006-2015, China will lose $558 billion in foregone national income due to heart disease, strokes and diabetes.
Air pollution is a major environmental risk to health and is estimated to cause approximately 2 million premature deaths worldwide per year.
Maternal mortality rates vary from 3.9 maternal deaths per 100,000 live births in Italy to 8.2 in the UK to 16.7 in the US to 34.1 in Russia to 47.0 in Thailand to 253.8 in India to 582.4 in Haiti to 1570.4 in the Central African Republic.
