A plane carrying a Congolese national en route from Paris to Detroit was diverted to Montreal due to newly imposed travel restrictions amid an Ebola outbreak. The passenger disembarked in Montreal, underwent assessment by a quarantine officer, and subsequently returned to Paris, according to Mark Johnson, a spokesperson for the Public Health Agency of Canada. The individual was determined to be asymptomatic, and the US-bound flight continued to Detroit on Wednesday.
US Government Announces New Travel Requirements
On Thursday, the US government announced that all Americans returning from high-risk Ebola-affected nations must rebook their travel to arrive at Dulles International Airport, located near Washington, DC, for mandatory screening. The US State Department’s Bureau of Consular Affairs specified that this requirement applies to US citizens and lawful permanent residents (LPRs) who were present in South Sudan, Uganda, or the Democratic Republic of Congo (DRC) within the previous 21 days.
Dulles Airport, situated about 30 miles outside Washington, DC, serves as the primary international gateway for the region. In the previous year, it handled approximately 29 million passengers, a record high, averaging around 79,500 travelers daily.
Enhanced Screening Measures
The notice stated that the Centers for Disease Control and Prevention (CDC) and the Department of Homeland Security’s Customs and Border Protection will implement enhanced public health screening at Dulles in response to the Ebola outbreak. It added: “The Dulles requirement applies to all passengers, including US citizens and LPRs, who were present in those countries. Please be prepared for flight changes or cancellations.” Washington, DC, is home to several hospitals specifically equipped to identify Ebola, safely isolate patients, and provide critical care.
WHO Declares Public Health Emergency
The World Health Organization (WHO) declared the Ebola outbreak in the DRC and Uganda a Public Health Emergency of International Concern on May 17. That same day, Rwanda closed its land border with the DRC to curb the virus’s spread. Earlier this week, the CDC announced increased screening and monitoring for arrivals from affected areas and restricted entry for non-US passport holders who had been in Uganda, the DRC, or South Sudan in the past 21 days.
The US State Department currently lists a Level 4 “Do Not Travel” advisory for the DRC due to crime, civil unrest, terrorism, and health risks. The CDC has issued a Level 3 “Reconsider Travel” notice for the country. The US embassy in the DRC warned: “The US government is extremely limited in its ability to provide emergency services to US citizens in Ituri province. Do not travel to this area for any reason.”
Outbreak Epicenter and Casualties
Ituri province is the epicenter of the outbreak, which has killed at least 136 people and is suspected of infecting nearly 600 others, including an American doctor working in the DRC who was evacuated to Germany for treatment. WHO Director-General Tedros Adhanom Ghebreyesus expressed deep concern about “the scale and speed of the epidemic,” which involves the rare Bundibugyo strain of Ebola with a mortality rate of up to 50 percent.
He anticipates a rise in cases and deaths in the coming weeks, noting that the risk of further spread within the DRC, South Sudan, and Uganda is high at national and regional levels, but the global risk remains low. CDC officials reiterated that the risk to the general US public is low but urged travelers to the affected areas to avoid contact with sick individuals and to monitor for Ebola symptoms for 21 days after leaving the DRC.
American Doctor Infected, World Cup Concerns
An American doctor working in the DRC tested positive for the virus, and six other Americans are feared to have been exposed. They have been evacuated to Germany and the Czech Republic for care. Concerns in the US are heightened because the DRC men’s national soccer team is scheduled to travel to the US to play in the World Cup against Portugal in Houston, Texas, on June 17. CDC officials did not provide specific screening details but stated that the agency is “actively working with FIFA to ensure safe traveling and passage” and to protect the American public during the competition.
The CDC is deploying personnel to the DRC and Uganda, along with personal protective equipment and additional resources, to provide direct technical assistance for aggressive disease tracking and contact tracing.
Historical Context and Transmission
The WHO reported that the first known suspected case, a health worker in the DRC, developed symptoms on April 24, but “patient zero” has not been identified, according to Dr. Anne Ancia, head of the WHO team in the DRC. This marks the 17th Ebola outbreak in the DRC since the virus was discovered in 1976, but only the third caused by the Bundibugyo strain. Previous Bundibugyo outbreaks occurred in 2007 and 2012. The most recent Ebola outbreaks in the DRC (2018 and 2020) each killed over 1,000 people. The largest Ebola outbreak occurred in West Africa from 2014 to 2016, with over 28,600 cases reported.
Ebola spreads through contact with blood or body fluids of an infected person, contaminated objects, or infected animals like bats or primates. Symptoms include fever, headache, muscle pain, weakness, diarrhea, vomiting, abdominal pain, and unexplained bleeding or bruising. The Bundibugyo strain has a mortality rate ranging from 25 to 50 percent. The more common Zaire strain can be treated with the drugs Inmazeb and Ebanga, and the Ervebo vaccine is administered during outbreaks. Dr. Ancia noted that officials are considering using the Ervebo vaccine, but any approved use would take months to become available, adding that she does not “see that in two months we will be done with this outbreak.”
