Two new cases of the human plague have been confirmed in Sante Fe County, New Mexico, according to health officials.
(NMDOH) The New Mexico Department of Health says the disease has been reported in two women, 52, and 62.
The first case was found earlier this month in a 63-year-old man. All three patients were hospitalized but there have been no deaths.
The disease, which once killed millions of people in Europe during the Middle Ages, can now be treated with antibiotics, according to the Centers for Disease Control and Prevention.
Although if no treatment, the disease can still cause serious illness and death.
Human plague usually occurs after an outbreak in which several susceptible rodents die, infected fleas leave the dead rodents and seek blood from other hosts.
Symptoms of the plague include sudden onset of fever, chills, headache, and weakness, according to NMDOH. There can also be painful swelling of the lymph node in the groin, armpit or neck.
The organization says around the house clean up areas where rodents live like wood and brush piles, junk and abandoned vehicles. They also suggest putting wood, hay, and compost as far away from your home as possible.
