Plague is widespread in all areas where houses are infested with fleas and rats, and therefore in conditions of poor hygiene.
The plague occurs mainly in three different forms, which can sometimes also be present simultaneously.
Here are the types of plague:
- Pulmonary plague: the bacterium infects the lungs. This form of the disease can be transmitted from person to person through the air or aerosols of infected people and it constitutes one of the most dangerous forms for the epidemic potential that characterizes it. The polmonary form can also result from the degeneration of other forms if they are not treated promptly.
- Bubonic plague: is the most common form of plague and manifests itself following the bite of infected fleas or by direct contact between material infected and lesions of a person’s skin. Typical manifestation of this form is the development of bubbons, inflamed enlargements of the lymphatic glands, followed by fever, headaches, chills and weakness.
- Septicemic plague: it comes from the multiplication of Pestis in the blood, and may be a consequence of complications of the two previous forms. It is contracted for the same causes as the bubonic one, and it is not transmitted from person to person. It causes fever, chills, abdominal pain, shock and prostration, bleeding of the skin and other organs, but does not manifest with bubonic.
What is the most deadly type?
Polmonary plague: If it is not cured in time, it almost certainly leads to death from acute pulmonary edema. If left untreated early, the lung form is fatal in almost all cases
Bubonic plague: in serious cases, the infection spreads in the body, causing cardiovascular insufficiency, necrosis that usually start from the fingers or feet and then expand slowly, kidney complications or internal bleeding. In the absence of treatment, the disease can evolve towards this stage and easily lead to death. Alternatively, in less severe cases, the fever stops after about two weeks and the bubonic excretion pus deflating and forming a scar.
The onset of septicemic plague is usually fatal in a very short time, on the order of one day, if not cured.
