Without the mobilization of sufficient resources and the backing of  sustainable government funding, these developing countries failed to adequately provide the treatment and resources necessary to combat tuberculosis. Vietnam
According to the WHO, Vietnam ranks 13th on the list of 22 countries with the highest tuberculosis burden in the world. Nearly 400 new cases of TB and 55 deaths occur each day in Vietnam. In 1989, the Ministry of Health in Vietnam addressed the tuberculosis burden by establishing the National Institute of Tuberculosis and Lung Diseases and implemented the DOTS strategy as a national priority. Vietnams health service system consists of four different levels: the central level headed by the Ministry of Health (MOH), provincial health services, district health services, and commune health centers". These departments worked with the National Institute of Tuberculosis and Lung Diseases to ensure that there were treatment and prevention plans for long-term reduction of tuberculosis. In 2002, Vietnam also implemented a communication plan to provide accurate educational information to respond to any barriers or misperceptions about tuberculosis treatment. The government worked with the World Health Organization, Center for Disease and Control Prevention, and local medical non-profits such as Friends for International Tuberculosis Relief to provide information about the causes of TB, sources of infection, how it is transmitted, symptoms, treatment, and prevention. The National Tuberculosis Control Program works closely with the primary health care system at the central, provincial, district, and commune levels which has proven to be an incredibly imperative measure of success.
Causes
The slowing of the bodys basal metabolic rate associated with hypothyroidism
Pernicious anemia where there is antibody production against parietal cells which normally produce gastric acid. The use of antacids or drugs that decrease gastric acid production (such as H2-receptor antagonists) or transport (such as proton pump inhibitors). A symptom of rare diseases such as mucolipidosis (type IV). A symptom of Helicobacter pylori infection which neutralizes and decreases secretion of gastric acid to aid its survival in the stomach. A symptom of atrophic gastritis or of stomach cancer. Radiation therapy involving the stomach. Gastric bypass procedures such as a duodenal switch and RNY, where the largest acid producing parts of the stomach are either removed, or blinded. VIPomas (vasoactive intestinal peptides) and somatostatinomas are both islet cell tumors of the pancreas. Pellagra, caused by niacin deficiency. Chloride, sodium, potassium, zinc and/or iodine deficiency, as these elements are needed to produce adequate levels of stomach acid (HCl). Sjögrens syndrome, an autoimmune disorder that destroys many of the bodys moisture-producing enzymes
Ménétriers disease, characterized by hyperplasia of mucous cells in the stomach also causing excess protein loss, leading to hypoalbuminemia. Presents with abdominal pain and edema

Risk Factors
Age
It was found that the incidence of achlorhydria in patients under the age of 60 was around 2.3%, whereas it was 5% in patients over the age of 60. In a persons 30s, the prevalence is about 2.5%, and increases to 12% in a persons 80s. An absence of hydrochloric acid increases with advancing age.
