Tuberculosis: Causes, Symptoms and Treatments

TB is an infectious disease that usually affects the lungs. It is the second greatest killer due to a single infectious agent worldwide, and in 2012, 1.3 million people died from the disease, with 8.6 million falling ill.

Fast facts on tuberculosis:
- In 2012, 1.3 million people were believed to have died because of tuberculosis with an estimated 8.6 million new cases of TB worldwide.
- The World Health Organization estimates that 9 million people a year get sick with TB, with 3 million of these "missed" by health systems.

- Tuberculosis is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs, although it can also affect other organs such as the kidneys and heart.
- TB can either be active or latent (where no symptoms occur, and the condition cannot be passed on).
- TB symptoms (cough, fever, night sweats, weight loss etc.) may be mild for many months, and people ill with TB can infect up to 10-15 other people through close contact over the course of a year.
- TB is an airborne pathogen, meaning that the bacteria that cause TB can spread through the air from person to person.
- People with compromised immune systems are most at risk of developing active TB and dying from the disease; people with HIV are 26-31 times more likely to develop TB.
- Tobacco use has been found to increase the risk of developing active TB with more than 20% of TB cases worldwide attributable to smoking.
- TB bacteria can develop a resistance to antibiotics that fail to kill them completely.
- The most common diagnostic test for tuberculosis is a skin test.
- The majority of TB cases can be cured with antibiotic treatment, with isoniazid and rifampicin the two most powerful, first-line (or standard) anti-TB drugs. TB bacteria can develop a resistance to antibiotics that fail to kill them completely.
- It is vital that any courses of treatment given are fully completed to increase the chance of successful eradication of infection and to reduce the risk of antibiotic resistance developing.

- Malaria occurs mostly in poor, tropical and subtropical areas of the world
- Malaria was eliminated from the US in the early 1950s, but the mosquitos that carry and transmit the malaria parasite still remain, creating a constant risk of reintroduction
- Reported malaria cases in the US reached a 40-year high of 1,925 in 2011
- A malaria vaccine for humans is close to being approved for use in Europe
- An estimated 3.4 billion people in 106 countries and territories are at risk of malaria - nearly half of the world's population
- Annual funding for malaria control in 2013 was three times the amount spent in 2005, yet it represented only 53% of global funding needs
- Malaria incidence rates are estimated to have fallen by 30% globally between 2000 and 2013 while estimated mortality rates fell by 47%
