The first human case of the plague in Colorado since 2015 was confirmed by the state’s Department of Public Health earlier this summer.
The person caught the plague after exposure to infected squirrels as local health officials urge caution and warn residents that it’s not uncommon for the disease to be present in the state at this time of year.
The resident from southwest Colorado had septicemic plague, which is in the blood and cannot be spread to other people.
The person recovered and no other cases were identified.

Colorado Department of Public Health has issued a warning for residents to use caution
‘Plague has been present in Colorado since at least the 1940s, and cases in wild rodents in Colorado are reported most years,’ Dr Jenifer House, Colorado’s public health veterinarian, said in a statement.
‘While we see most plague activity during the summer, the disease can be found in rodents year-round and sometimes spills over into other wildlife species as well as domestic cats and dogs.’
There have been 21 human cases of the plague in Colorado since 2005 but this is the first in the past five years. Eight of these cases were in 2014, the worse year for human cases in the past 15 years.
The majority of the cases were in those aged between 25 and 64 although there were three cases in children under 14. Sixty percent of the cases were found in women.
There have been 558 cases of the plague found in animals in Colorado since 2005. The largest number of cases was found in rodents.
There were zero cases of plague reported in the state in 2018 but it grew to four cases again last year.
The department issued a health warning earlier this week after a squirrel tested positive for the bubonic plague in Jefferson County in what is being described as ‘an increase of reported plague activity’.

The sick squirrel was found in the city of Morrison, southwest of Denver, but cases have also been found this year in animals in limited access areas of Adams and Broomfield counties.
‘Plague is an infectious disease caused by the bacteria Yersinia pestis, and can be contracted by humans and household animals if proper precautions are not taken,’ Jefferson County Public Health said.
The health officials reassure that so long as proper precautions are taken, the risk of getting plague is ‘extremely low.’
The Colorado Department of Public Health and Environment is reporting there has been an increased amount of plague activity in the state having already been found in Broomfield, northwest of Denver.

What is the plague?
Bubonic plague is the most common form of plague and is spread by the bite from an infected flea.
The infection spreads to immune glands called lymph nodes, causing them to become swollen and painful and may progress to open sores.
Plague is an infectious disease caused by the bacteria Yersinia pestis, and can be contracted by humans and household animals if proper precautions are not taken.
Human-to-human transmission of bubonic plague is rare and is usually caught from animals.
Humans may be infected with plague through bites from infected fleas, by the cough from an infected animal or by direct contact (e.g., through a bite) with blood or tissues of infected animals.
Symptoms of plague may include sudden onset of high fever, chills, headache, nausea and extreme pain and swelling of lymph nodes, occurring within two to seven days after exposure.
Plague can be effectively treated with antibiotics when diagnosed early.
Septicemic plague is an infection of the blood and is also most commonly spread by bites from infected fleas or handling an infected animal.
It can occur as the first symptom of plague, or may develop from untreated bubonic plague.
Symptoms are similar to the bubonic plague but skin and other tissues may also turn black and die, especially on fingers, toes, and the nose.
Humans are able to be infected with plague by getting flea bites or from being coughed on by an infected animal.
The bubonic plague is a bacterial disease spread by fleas living on wild rodents. It kills in less than 24 hours if not treated promptly.
Cats in particular are susceptible to the plague and may die if not treated promptly with antibiotics.
Cats similarly can also contract the plague from flea bites, or that of rodents.
Dogs are less susceptible to contracting the plague but they are able to pick up fleas which could be carrying the disease.
Symptoms of plague are known to include a fever, chills, headache, nausea and extreme pain and swelling of lymph nodes, occurring within two to seven days after being exposed.
There are no publicly available vaccines to prevent plague in people but, if caught early, it can be successfully treated with antibiotics in both people and pets.
Jefferson County Public Health recommends the following precautions to protect against plague:
- Eliminate all sources of food, shelter and access for wild animals around the home.
- Do not feed wild animals.
- Maintain a litter and trash-free yard to reduce wild animal habitats.
- People and pets should avoid contact with sick or dead wild animals and rodents.
- Use precaution when handling sick pets.
- Have sick pets examined by a veterinarian.
- Consult with your veterinarian about flea and tick control for your pets.
- Keep pets from roaming freely outside the home where they may prey on wild animals and bring the disease home with them.
Last week, the World Health Organization (WHO) said it was ‘carefully’ monitoring a case of bubonic plague in China after being notified by the authorities in Beijing.
A WHO official claimed the situation was being ‘well managed’ by China and not considered to represent a high risk.

Two other cases were confirmed in Khovd province in neighboring Mongolia at the end of June involving brothers who had eaten marmot meat, China’s state news agency Xinhua said.
Bubonic plague is one of the most devastating diseases in history, having killed around 100 million people in the 14th century.
‘Bubonic plague has been with us and is always with us, for centuries,’ WHO spokeswoman Margaret Harris told reporters at a virtual briefing.
‘We are looking at the case numbers in China. It’s being well managed.
‘At the moment, we are not considering it high-risk but we’re watching it, monitoring it carefully.’
BUBONIC PLAGUE: WIPED OUT A THIRD OF EUROPE IN THE 14TH CENTURY
Bubonic plague is one of the most devastating diseases in history, having killed around 100million people during the ‘Black Death’ in the 14th century.
Drawings and paintings from the outbreak, which wiped out about a third of the European population, depict town criers saying ‘bring out your dead’ while dragging trailers piled with infected corpses.
Bubonic plague is caused by a bacterium known as Yersinia pestis, which uses the flea as a host and is usually transmitted to humans via rats.

The disease causes grotesque symptoms such as gangrene and the appearance of large swellings on the groin, armpits or neck, known as ‘buboes’.
It kills up to two thirds of sufferers within just four days if it is not treated, although if antibiotics are administered within 24 hours of infection patients are highly likely to survive.
After the Black Death arrived in 1347 plague became a common phenomenon in Europe, with outbreaks recurring regularly until the 18th century.
Bubonic plague has almost completely vanished from the rich world, with 90 per cent of all cases now found in Africa.
However, there have been a few non-fatal cases in the U.S. in recent years, while in August 2013 a 15-year-old boy died in Kyrgyzstan after eating a groundhog infected with the disease.
Three months later, an outbreak in a Madagascan killed at least 20 people in a week.
A year before 60 people died as a result of the infection, more than in any other country in the world.
Outbreaks in China have been rare in recent years, and most have happened in remote rural areas of the west.
China’s state broadcaster said there were 12 diagnosed cases and three deaths in the province of Qinghai in 2009, and one in Sichuan in 2012.
In the United States between five and 15 people die every year as a result, mostly in western states.
