As I mentioned before about carpet fleas behavior, they are the chinches of pets, livestock and human beings. These are laterally flattened and wingless insects. Carpet fleas can go quickly by jumping, using their legs and a spring-like mechanism in the bodies. They are competent of outstanding leaps, covering spaces up to one hundred times of their body length.
Carpet fleas will feed on humans and attack come when the fleas are denied to access their normal host. The worst human cases are noted when the infested pests are removed from the house. Humans are normally bitten near the ankles and lower legs. Skin can be itchy, reddened and swollen. Skin irritation is caused by flea spittle injected into the organic structure during the feeding to prevent blood coagulating. Infections can grow if the bites are itched, even worse, fleas can send parasites and dangerous diseases to animals and humans. The most fatal flea disease is plague.
Plague is a disease of rodents that can be spread to human beings and another animal infected by fleas. In human, plague has 3 forms:
- bubonic plague causes the lymph glands infection;
- septicemia plague causes infection of the blood;
- pneumonic plague causes infection of the lungs.
Pneumonic plague is the most infectious variety because it can spread from person to person in airborne droplets.
Plague is a potentially critical disease made by an infection of the bacterium Yersenia Pestis. Plague has great historical importance including three major pandemics such as the devastating Black Death of the Middle Ages. Since its establishment in the US at the turn of the century, plague has been a persistent concern in California, Arizona, Colorado and New Mexico. In the world, there are 1,000 to 2,000 cases each year. On the eighties epidemic plague occurred annually in Africa, Asia, or South America.
The septicemia and bubonic plague were transferred with direct contact with a flea, while the pneumonic plague was transferred through airborne droplets of saliva coughed up by bubonic or septicemia infected humans.
Domestic cats and dogs are readily infected by carpet fleas or from consuming infected wild rodents. Cats and dogs may serve as a root of infection to persons exposed to them. Pets may also bring plague-infected fleas into the home.
Once a human is bitten by an infected flea or infected by handling an infected animal, the plague bacterium move through the bloodstream to the lymph nodes. The lymph nodes swell, forming the painful lumps (“buboes”) that are feature of bubonic plague. Other symptoms are fever, head ache, chills, and extreme fatigue. Some people have gastrointestinal symptoms.
Whenever bubonic plague becomes untreated, the bacteria can breed in the bloodstream and cause plague septicemia, dangerous blood infection. Signs and symptoms are fever, chills, fatigue, abdominal pain, shock, and bleeding into the skin other organs. Untreated septicemia (blood poisoning) plague is usually fatal.
Pneumonic plague, or plague pneumonia, produces when the bacteria infect the lungs. People who are infected by plague pneumonia have high fever, chills, trouble breathing, coughing, and bloody phlegm. Plague pneumonia is believed as a common health emergency since a cough can distribute the disease to others quickly. Untreated pneumonic plague is commonly fatal.
