(DOUGLAS COUNTY, Colo.) — Colorado public health officials are investigating the death of an adult resident as a result of hantavirus.
The Colorado Department of Public Health and Environment and the Douglas County Health Department said the death is not linked to the outbreak on the MV Hondius cruise ship, which led to 11 confirmed and probable cases, including two confirmed deaths and one suspected death.
The individual lived in Douglas County — located just south of Denver — but information about the patient’s name, age and sex were not immediately available.
Health officials said the individual was infected by the Sin Nombre hantavirus, which is the most common cause of hantavirus pulmonary syndrome (HPS) in North America.
HPS symptoms typically appear from one to eight weeks after contact with the virus, with early signs including fever, fatigue and muscle aches, according to the Centers for Disease Control and Prevention. Half of HPS patients will experience headaches, chills, dizziness, nausea, vomiting, diarrhea and abdominal pain.’
Between four and 10 days after the initial phase of illness, symptoms including coughing, shortness of breath and tightness in the chest can emerge, the CDC said, adding that a patient’s lungs can fill with fluid.
“Hantavirus infections caused by the Sin Nombre hantavirus occur regularly in Colorado, usually in the spring and summer, and can cause a severe and sometimes deadly respiratory disease,” according to public health officials. “In Colorado, the deer mouse is the rodent species that most commonly exposes people to the virus. Avoiding exposure to rodents and their urine, feces, saliva, and nesting materials is the best way to prevent infection.”
According to the CDC, there were six cases of Hantavirus in Colorado from 2020 to 2023.

(LONDON) — An epidemiologist from the World Health Organization (WHO) said Thursday that the suspected hantavirus cluster aboard a cruise ship is not the beginning of another COVID-19 pandemic.
Eight cases are currently being reported by the WHO, including five laboratory-confirmed cases and three suspected cases. Of those eight cases, three have died.
Dr. Maria Van Kerkhove, an infectious disease epidemiologist and acting director of epidemic and pandemic management at the WHO, was asked during a press conference what the difference was between this cluster and the early days of the COVID pandemic.
“I want to be unequivocal here. This is not SARS-CoV-2. This is not the start of a COVID pandemic. This is an outbreak that we see on a ship,” Van Kerkhove said.
Van Kerkhove explained that hantavirus doesn’t spread in the same way that coronaviruses do, but rather through “close, intimate contact.” Most hantaviruses don’t transmit from person to person.
“The actions that are being taken on board [the ship] are precautionary to prevent any onward spread,” she added.
There appears to be one confirmed case and two suspected cases that have not been added to the WHO’s official count yet.
Officials told ABC News a female individual, who was on a KLM flight with the Dutch female patient who later died, developed symptoms and was admitted to a hospital. Leiden University Medical Centre in the Netherlands confirmed on Thursday that the female patient has hantavirus and is receiving care.
Additionally, two Singapore residents who were on board the ship are currently being monitored. Singapore’s Communicable Diseases Agency said it was notified of the individuals on May 4 and May 5.
“They have been isolated at the National Centre for Infectious Diseases, where they are being tested for hantavirus. The risk to the general public in Singapore is currently low,” the agency said.
The agency added that test results are pending, with one resident having a runny nose and the other is asymptomatic.
Three deaths have been recorded so far, including a married Dutch couple. The 70-year-old male patient died on April 11, and his body was taken off the ship on the island of St. Helena on April 24. His 69-year-old wife disembarked on the same day, and her health rapidly deteriorated. She died at an emergency department in South Africa on April 26.
A third passenger, a German woman, presented with pneumonia symptoms starting on April 28, according to the WHO. The woman died on May 2 from causes not yet known, according to Oceanwide Expeditions, which operates the cruise ship.
The WHO said 29 people disembarked on St. Helena on the same day that the body of the Dutch male patient and his wife disembarked.
They traveled to 12 countries: Canada, Switzerland, Germany, Denmark, Great Britain, St. Kitts and Nevis, Netherlands, New Zealand, Singapore, Sweden, Turkey and the United States.
The disembarked guests have all been contacted by Oceanwide Expeditions. In the U.S., local authorities in three states — Arizona, Georgia and California — are monitoring the disembarked passengers and are conducting contact tracing, None have shown signs of illness at this time.
Anais Legend, technical lead for viral hemorrhagic fevers at WHO, said during the press conference on Thursday that “step-by-step guidance is being developed” for the disembarked passengers and that the WHO is coordinating with national authorities.
Anyone with any signs of symptoms will be isolated while other passengers have their risk exposure evaluated.
Public health experts said they expected a more robust response from the Centers for Disease Control and Prevention (DC) and the National Institutes of Health.
“The CDC would typically be asked by WHO or by a country to help in technical assistance,” Dr. Carlos del Rio, an H. Cliff Sauls distinguished professor of medicine at the Emory University School of Medicine, told reporters on Thursday.
Typically, CDC teams would be deployed to an area, he said, and the teams would perform contact tracing and interviews and conduct an outbreak investigation.
“I would envision by now, many, many days ago, we would have seen a team from CDC deployed to the area,” he added.
Dr. Jeanna Marrazzo, CEO of the IDSA, added that she would have expected a CDC press briefing, an alert from the agency’s Health Alert Network or information from the NIH on potential treatments in the pipeline that could receive emergency use authorization to help treat hantavirus patients.
Marrazzo said she is not aware that conservations about potential therpaies at NIH aren’t happening but that it “doesn’t give me a lot of assurance or reassurance that we are not hearing any of that.”
The WHO said during Thursday’s press briefing that the U.S. is coordinating with the global health agency in a technical capacity.
Because the cluster is limited and confined to a cruise ship, the “idea of sending messages across the world and panicking everyone is not required,” said Dr. Abdirahman Mahmoud, director of the WHO’s health emergency alert and response operations.
He added that the WHO is “informally” aware that contact tracing has been done of the U.S. passengers who disembarked last month and are back home.

(NEW YORK) — There have been at least 733 confirmed measles cases reported across the nation, the latest data from the Centers for Disease Control and Prevention showed Friday.
It comes as South Carolina is dealing with the largest outbreak recorded since measles was declared eliminated within the U.S. in the year 2000.
A total of 20 states have reported cases so far including Arizona, California, Florida, Georgia, Idaho, Kentucky, Minnesota, Nebraska, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Utah, Virginia, Washington, and Wisconsin.
Last year had a record breaking 2,276 cases nationwide, the highest number since 1992. There were also three measles deaths, the first in a decade.

(NEW YORK) – An Ebola outbreak has been confirmed in the Ituri province in Democratic Republic of the Congo, according to Africa Centres for Disease Control and Prevention.
As of the latest update, about 246 suspected cases and 65 deaths have been reported, mainly in Mongwalu and Rwampara health zones, officials said.
Africa CDC said that preliminary lab results from the Institut National de Recherche Biomédicale (INRB) have detected Ebola virus in 13 of 20 samples tested. Four deaths have been reported among laboratory-confirmed cases.
The latest outbreak comes around five months after Congo’s last Ebola outbreak was declared over after more than 40 deaths.
“Africa CDC is closely monitoring the situation and convening an urgent high-level coordination meeting today with the DRC, Uganda, South Sudan and global partners to reinforce cross-border surveillance, preparedness and outbreak response efforts,” officials said in a statement Friday.
