Extracts from this document...

Introduction

Tuberculosis Symptoms of active tuberculosis * Persistent cough. * Chest pains. * Weight loss. * Coughing up blood or phlegm. * Shortness of breath. * Loss of appetite. * Weakness or fatigue. * Fever. * Night sweats. Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis. It is spread by droplet infection. If someone who has Tuberculosis coughs then the infected droplets will stay in the air, if another person then breaths in the infected water droplets they will get Tuberculosis. There are two groups of people, who are considered to be at higher risk of developing TB than others they are, people with HIV and AIDS and people with Auto-immune illnesses (such as rheumatoid arthritis). ...read more.

Middle

The TB cases have risen from 5900 on 1998 to 6400 in 2005 this could be as result from many possible reasons, these include; * The Population has increased * An increase in people travelling abroad, therefore the disease can be brought into the country. The number of cases of Tuberculosis in a developing country are a lot higher than the number of cases in the United Kingdome. This could be because of poorer living conditions, less developed medical care, and also the milk may not be pasteurised. In a lot of cases, people who are infected with the TB bacterium, do not immediately develop the disease. ...read more.

Conclusion

The number of deaths, due to TB, have decreased in many developed countries since the beginning of the 20th century, particularly since the 1950's. Scientists believe that this is due to: * Improvements in living standards * Pasteurisation of milk * Spitting in public places discouraged Prevention and Control TB prevention and control takes two parallel approaches. In the first, people with TB and their contacts are identified and then treated. Identification of infections often involves testing high-risk groups for TB. In the second approach, children are vaccinated to protect them from TB (The vaccine is also known as the BCG). Unfortunately, no vaccine is available that provides reliable protection for adults. However, in tropical areas where the incidence of atypical mycobacterium is high, exposure to non-tuberculosis mycobacterium gives some protection against TB. ...read more.
