Two people in New Hampshire who recently traveled to Wuhan, China, where the recent coronavirus outbreak originated, tested negative for the disease, health officials announced.

The patients were screened after developing respiratory symptoms, the New Hampshire Department of Health and Human Services announced Monday. The two displayed mild illness, sought health care and have fully recovered, the agency said in a statement Thursday.

Health officials in the state will continue to monitor for suspected cases of the coronavirus, named 2019-nCoV, but have yet to identify any infected people. The risk of the disease to the New Hampshire is low, according to the agency.

“Rapid identification and testing of individuals is critical in preventing the spread of this novel coronavirus," Dr. Benjamin Chan, an epidemiologist in New Hampshire, said in the agency’s statement. “We will continue to work with healthcare providers to monitor for any additional suspect cases that may occur in New Hampshire and test as appropriate based on a person’s symptoms and travel to affected areas in China.”

China has reported 170 deaths from the coronavirus, and nearly 7,750 cases have been confirmed globally across more than 15 countries, including the United States, where five patients have been diagnosed with the disease since Jan. 21.

The Centers for Disease Control and Prevention has warned against all nonessential travel to China, and Boston Logan International Airport joined a number of U.S. airports earlier this week in screening passengers for the virus.

New Hampshire health care providers have been asked to alert the state’s Department of Health and Human Services if they identify patients with recent travel to the Hubei Province of China, where Wuhan is located, and who become sick with a fever or respiratory symptoms within 14 days of their visit.

Officials are still learning about how the virus is spread but said it can be transmitted through “respiratory droplets.” Symptoms have mainly included a fever, coughing and difficulty breathing. There are currently no vaccines available to protect against the illness.

“While the risk of contracting coronavirus remains low in the U.S., there are protective measures people can take to reduce their risk of illness,” the New Hampshire agency said in its statement. “People can take precautions similar to those taken during flu season to prevent the spread of illness: frequent handwashing with soap and water, avoiding close contact with sick people, staying home if you are sick, covering your nose and mouth when sneezing or coughing, and cleaning and disinfecting surfaces and objects that may be contaminated with germs.”

The disease falls into a family of viruses common among various animals. The animal-version of the illness rarely infects humans, but once it does, it can spread between people through MERS and SARS, according to the CDC’s website.
