Bubonic PlagueBubonic plague is another life-threatening disease caused by bacteria. The bacteria that cause the plague are the yersiniapestis variety. The different kinds of bubonic plague include the common form that spreads through certain rats and fleas. Sepsis is a form of the disease when the bloodstream is infected with the bacterium. Pneumonic plague refers to a condition when the bacterium infects the lungs. And, the most harmless form is called the abortive form. The fever persists for a while, before abating. The incubation period for the infections that are life-threatening range from 2 to 7 days.
CholeraThe term indicates 'flow of bile', in Greek. It is an intestinal infection caused by the vibriocholerae bacteria that contaminates food stuff and water. Cholera is a diarrheal disease that is, spread via consumption of undercooked food, deficiency of hydrochloric acid and poor hygiene. The symptoms only surface around three days after infection sets in. The signs include diarrhea, abdominal cramps, severe dehydration, dryness in the mouth and skin, low urination, low blood pressure, fatigue and nausea. In the absence of timely treatment, the patient can die in a matter of hours.
PertussisPertussis is also referred to as 'whooping cough'. The bacteria that spread this disease are referred to as bordetellapertussis. The disease takes a toll on the immune system of younger people within 6 weeks. The symptoms of Pertussis include nausea, severe coughing, and fever. The term 'whooping cough' is the result of the sound that the patient makes while coughing. Sadly, the disease spreads in underdeveloped regions of the world, where the access rate of the expensive antibiotics is highly questionable.
Typhoid FeverAlso known as gastric fever, abdominal typhus, infantile remittent fever, slow fever, untreated typhoid fever progresses in four individual stages, each lasting approximately one week. A characteristic symptom of typhoid is a slowly progressive fever, as high as 40 °C (104 °F), gastroenteritis, profuse sweating and sometimes rash is also observed. Diarrhea and constipation can occur. By the third stage fever becomes very high and dehydration ensues. Fatal complications like Internal bleeding or intestinal hemorrhage may also occur. A course of antibiotics is prescribed to treat typhoid. Improvement in the patient's condition is observed after 1-2 days of antibiotics and a complete recovery is possible after 7-10 days. fever may be spread through poor hygiene habits and public sanitation conditions, and sometimes also by flying insects feeding on feces. Public education campaigns encouraging people to wash their hands after defecating and before handling food are an important component in controlling spread of the disease.
TuberculosisTuberculosis is an infectious disease. The bacteria that cause tuberculosis are called mycobacterium tuberculosis. People with TB or tuberculosis cough excessively and suffer a terrible pain in the chest. They cough up blood and display excessive weight loss, fatigue, loss of appetite and a persistent fever. TB spreads from the infected person to others in the peripheral. When the patient sneezes, coughs or spits, the bacteria infect those around. Latent tuberculosis is a condition in which the infected person remains unaware of the infection because of milder symptoms. But, the condition becomes active very often, threatening the patient's life span in the absence of proper antibiotics. Pulmonary tuberculosis affects a person's lungs, while military tuberculosis results in infection of the lungs that slowly spreads to the heart, liver and brain. Tuberculosis, also affects the skin and bones.
