Old/New TuberculosisBernice Clark ▼ |
World Health Organization marked World Tuberculosis Day with new alarming data on March 24. Around million and a half people died of tuberculosis during 2006 while Africa is faced with the worst tuberculosis epidemic since antibiotic came in use. Of nine millions new data cases marked annually, half of the million are those resistant on numerous drugs. And almost any drug is not effective in the case of extensively resistant tuberculosis, which number is also on the raise. For spreading of the disease World Health Organization blames partly a growth of international voyages in the last fifty years.
They accent that contagion passenger or an insect who wanders in a plane can transfer infection in another part of the world in only a few hours. Tuberculosis is the biggest killer among bacterial diseases and that fact even the richest countries doesn't take seriously enough. Contagious disease spreads over the world much more faster then earlier, endangering health, economy and security of all countries.
Tuberculosis or TB is an infection that primarily attacks patient's lungs. Its appearance changes depending on people's social-economic conditions and resistance on drugs in use. Primary role in reducing tuberculosis play vaccination and mass conventional radiography. Tuberculosis spreads in an environment by air when patient infected with tuberculosis disperse small drops on healthy people by coughing, sneezing or just by talking.
If patient with tuberculosis is not treated, he dies. Tuberculosis infection is caused by Koch bacilli (Mycobacterium Tuberculosis) with characteristic appearing of knots. Transferred by blood and lymph, tuberculosis can attack the other organs as liver, spleen, kidneys, lymph nodes, brain, bones, digestive tract, uric and genital system.
In children who are not vaccinated in the first three years of age disease has adverse outcome. People who are vaccinated have good prognosis except in cases when their body is weakened by some other sickness.
Miliar tuberculosis is a specific form of tuberculosis. It is characterized by tiny knots which attack all organs, especially lungs. It starts very abruptly with high temperature, shaking, heavy breathing, fasten measured pulls and blue coloured skin and mucous (cyanosis). Otherwise, out of lungs tuberculosis attacks for example brain or kidney, and usually is not contagious for other people.
Chronic tuberculosis is the most frequent form of tuberculosis. Its characteristics are slightly higher temperature, soft caught, tiredness, loss of weight, spitting blood, and sweating during the night. Even then symptoms can vary depending on which organ is caught by tuberculosis.
Tuberculosis test and RTG screening are some of clinical methods for diagnosing TB. However, negative reaction doesn't rules out infection. Some diseases that heighten the risk of tuberculosis are smoking, diabetes, malign diseases, HIV, AIDS, illegal drugs and alcohol addiction.
Tuberculosis must be treated in hospital for infection to be stopped. Healing continues three months after the last negative medical results. ■
