TB is an infectious disease caused by a bacterium called Mycobacterium tuberculosis. It's mainly a disease that affects your lungs, but it can affect other parts of your body such as your skin or other organs.
TB is passed on from person to person by droplets carried in the air, usually from coughs and sneezes. Your body's immune system, which fights infection, usually destroys the germs once they are inhaled.
In a small number of people, the immune system successfully builds a defensive barrier around the infection. The bacteria stay in the body, but you won't usually have any symptoms and can't pass the infection on to other people. This is called latent TB.
Sometimes, the immune system fails to destroy the bacteria, or latent TB becomes active years later. This is more likely to happen if your immune system becomes weakened by other problems such as HIV, poorly controlled diabetes, or if you are underweight. At first, a TB infection normally affects the lungs. This is called pulmonary TB. However, TB often spreads to the lymph nodes (glands throughout your body that are part of your immune system). It can also affect your bones, joints and kidneys. TB can also cause meningitis (inflammation of the membranes surrounding the brain and spinal cord), though this is rare.
The symptoms of tuberculosis infection in your lungs may include:
a persistent cough - there may also be lots of phlegm, sometimes containing blood
fever
tiredness
loss of appetite
weight loss
night sweats
chest pain when you breathe in, caused by inflammation of the membranes lining your lungs (pleurisy)
If you have TB in other parts of your body, you may also have other symptoms such as swollen glands in your neck, pain in your joints or a headache.
Causes of tuberculosis
You can catch TB by breathing in droplets in the air that contain the bacterium M. tuberculosis. These are spread through the air when someone with TB coughs or sneezes. Only some people with TB in their lungs are infectious to others.
Although it's spread through the air, you need to be closely exposed to a person with TB for some time before you catch it. People most commonly catch TB from people they live or work with. When you start treatment for TB, you remain infectious to others for the first two weeks.
Although anyone can get TB, it's quite difficult to catch in the UK. You're more likely to get TB if you:
already have a weakened immune system (for example if you have HIV/AIDS or are taking medicines that suppress your immune system)
have diabetes
have regular close contact with people who have TB lung infection
are young or elderly
live in overcrowded housing
are dependent on drugs or alcohol
are in poor health generally and have been for some time
Diagnosis of tuberculosis
To diagnose active TB infection you will usually be asked to give at least three separate samples of your phlegm for testing. These will be examined in a laboratory. A chest X-ray can also be used to diagnose active TB.
To diagnose latent TB you can have a skin test called a Mantoux test. This test involves injecting the tuberculin protein just under your skin, usually on the inside of your forearm. Over the next two to three days a reaction to the injection will develop. This reaction is then graded.
The greater the reaction the more likely it is that you have TB infection. If this is the case your doctor may ask you to have further tests.
If you are diagnosed with TB those people who have been in close contact with you, such as family members or work colleagues, may also be tested for the infection.
Treatment of tuberculosis
TB can be completely cured by taking antibiotics. Most people with either active or latent TB are treated with a combination of four antibiotic tablets which kill the bacteria. Treating latent TB prevents the infection from becoming active in the future.
You will probably have treatment at home and won't need to go to hospital, unless you're very unwell. There are teams of doctors and nurses who specialise in caring for and treating people with TB.
Tuberculosis in the 19th Century Factory
Tuberculosis is something we don't often think about anymore. But 19th century
Henry Thoreau died of consumption at 44
Concordians were frighteningly aware of the symptoms: the flushed cheeks, the bright eyes, fever, loss of appetite, and most of all, the cough. It was feared, but regarded with a peculiar resignation because it was so unavoidable. It was dreaded, but at the same time romanticized. It was a disease that reflected the culture of its time: the victim slowly, gracefully fading away, transcending their corporeal body, their immortal soul shining through. In reality, tuberculosis, commonly called consumption in the 19th century, killed more people in New England, particularly in the Boston area, than any other disease. It affected the poor more often than the wealthy, females more than males, and people of all ages. Anyone could be a victim, but it was especially prevalent among young adults, cruelly striking down those in the prime of their lives. Unfortunately for 19th century New Englanders, the disease was not well understood. Its cause would not be discovered until 1882. In the meantime, beliefs about the disease reflected the cultural and scientific thinking of the time. It was thought that it might be a vaguely environmental, "something in the air"; but more likely caused by the victim's own constitution, either physiologically, psychologically, or both. It was not believed to be contagious, so those suffering from the disease were not avoided. Recommended steps toward prevention included fresh air, a wholesome diet, exercise, and healthy manual labor. In "Consumption in America," a series of three articles published in the Atlantic Monthly in 1869, Dr. Henry Bowditch theorized that damp soil was the main cause of consumption. He advised towns to drain wet areas and families to occupy only sunlit homes sited on dry soils.
The disease affected Concordians in two ways: by the sheer number of people who contracted it and by the way it descended upon certain families. Thanks to the record- keeping and analysis done by men like Lemuel Shattuck, Ezra Ripley, and Edward Jarvis, there are statistics on deaths in Concord which detail dates, ages, and causes. These records show that consumption was the leading cause of death in Concord in the first half of the 19th century. The same was true in neighboring towns: Acton, Billerica, Bedford, and Carlisle all exhibiting the similar results. Tuberculosis was everywhere.
comsumption can affect fleshy parts of thebody, too, like this woman's ravaged face
Concord families unduly affected by consumption included the Barretts, Buttricks, Melvins, Heywoods, and Hosmers. In these families, death from consumption took place both within as well as across generations. In the records can be found family tragedies, such as the case of Lucy and Lemuel Phillips, sister and brother, who died within a month of each other in 1802. She was 19 and he was 22. The Dudley family lost Rebecca in 1803 (age 19), Mary in 1804 (age 26) and their father, Samuel, in 1806. Mary E. Wright died in January of 1837 at age 42 and her daughter, Mary, in April at age 16. Cases like these are found throughout the records. Caring for each other and simply living in the same home were enough to spread consumption through a family.
Some of Concord's most revered families fell victim to tuberculosis. Both Emerson and Thoreau came from what were recognized as "consumptive" families- those with many cases. The first known case in the Emerson family was that of Reverend William Emerson, Ralph Waldo's father, who had the disease when he died in 1811 at the age of 42. Ruth Haskins Emerson went on to raise their children herself, and by her hard work the Emerson brothers grew to adulthood and went on to attend Harvard College. However, all had symptoms of tuberculosis. Both Edward and Charles died of it while in their late twenties. Waldo appeared to have symptoms of the disease at various times in his life, once writing of having "a mouse gnawing at his chest," but died of an unrelated illness at age 79.
Emerson's marriage to Ellen Tucker was prematurely ended by tuberculosis. Their relationship had a storybook quality to it: two gifted young people in the midst of passionate first love, a world of opportunity awaiting them. She was just 16 when they met, attractive, intelligent, and energetic, and within a year they were engaged. But both romantically and tragically, she was also from a consumptive family and already had the disease. They were married in September of 1829 and she died on February 8, 1831, only nineteen years old. Their relationship had been intensified by the knowledge that it would be necessarily brief. "My angel is gone to heaven this morning and I am alone in the world and strangely happy," he wrote to his Aunt Mary Moody Emerson two hours after Ellen had died. Her struggle was over. His second wife Lydian would later graciously name their first daughter after Ellen.
Henry David Thoreau succumbed to tuberculosis at the age of 44. For Thoreau, too, it was a family illness. His grandfather had died of it in 1801, and when Henry's father died in 1859 his symptoms were consistent with tuberculosis. His brother John was living with it, though tetanus took him first, and their sister Helen became a victim in 1849 at age thirty-six. Henry himself had developed a severe cold in the early winter of 1860 that kept him housebound and diminished his productivity. The following spring he took a trip to Minnesota (at the time thought to be a favorable place for recovery from respiratory problems), but when he returned two months later his health had further declined. He continued to work on various projects and papers, but he was failing. With his sister Sophia by his side, he died on the morning of May 6th, 1862.
Was there a citizen in 19th century Concord who had not been touched by the loss of a friend or family member to consumption? Sisters, mothers, sons, daughters, fathers were lost to this omnipresent disease. It was an intimate, if unwelcome, part of everyone's life. And not until the advent of antibiotics could the lurking fear of consumption be put to rest.
