Humans get the plague through direct contact with infected animals or fleas. In the U. Human-to-human transmission is extremely rare. Since , the CDC has received reports of one to 17 cases of the plague per year.

In , 16 cases of plague were reported and, in , there were only 4 cases. The plague is most prevalent in Africa and is also found in Asia and South America. The most common type is the bubonic plague, which represents 80 to 95 percent of cases. The symptoms include fever, chills, weakness, and headache, followed by very painful and swollen lymph nodes, referred to as "buboes. When the plague gets into the blood, it can cause the septicemic plague, which represents 10 to 20 percent of cases, and triggers the entire immune system to fall into a dangerous condition called "sepsis.
It can also be spread through the air from infected humans or animals and can be fatal. The plague is a very serious illness, but is treatable with antibiotics, usually taken for seven to 14 days. Left untreated, people can still die from the plague. One of the ways to avoid the plague is to prevent contact with infected fleas by wearing repellent during activities such as camping, hiking, working outdoors.
Avoid sick or dead animals and wear gloves when handling or skinning potentially infected animals. Keep pets from running loose in areas where the plague is common, regularly treat pets for fleas and take sick animals to the vet right away. To avoid attracting infected rodents, keep foods in rodent-proof containers. People that may have been exposed to the plague by being within about six feet of a person or animal who has contracted the infection, can also take preventive antibiotics. NIAID-funded scientists have developed a rapid diagnostic test for pneumonic plague that can be used in most hospitals.

Ecology and Transmission
Diagnostics NIAID-funded scientists have developed a rapid diagnostic test for pneumonic plague that can be used in most hospitals. Experiments included various delivery methods, vacuum drying, sizing the bacterium, developing strains resistant to antibiotics, combining the bacterium with other diseases such as diphtheria , and genetic engineering. Scientists who worked in USSR bio-weapons programs have stated that the Soviet effort was formidable and that large stocks of weaponised plague bacteria were produced.
Information on many of the Soviet projects is largely unavailable. Aerosolized pneumonic plague remains the most significant threat. The plague can be easily treated with antibiotics, which some countries, such as the United States, have large supplies on hand if such an attack should occur, thus making the threat less severe.
