US health officials have announced new measures aimed at mitigating the risk of Ebola spreading within the United States, following growing international concern over a fresh outbreak in the Democratic Republic of Congo (DRC). Despite these precautions, authorities have stated that the immediate threat to Americans remains low.
New Screening Protocols for Travelers
The Centers for Disease Control and Prevention (CDC) has confirmed that travelers who have been in the DRC, Uganda, or South Sudan within the last 21 days will now face screening and monitoring upon arrival in the US. However, these new protocols will not apply to US citizens, US nationals, or lawful permanent residents, according to the CDC's order, which is set to remain in effect for 30 days.
Explaining the necessity of these steps, the CDC stated: "The risk of Bundibugyo virus disease introduction into the United States is heightened by the virus’s incubation period, which can extend up to 21 days, allowing infected individuals to travel internationally while asymptomatic and therefore unlikely to be detected through routine symptom-based screening measures."
Enhanced Domestic Preparedness
Beyond border controls, US officials are also committed to bolstering nationwide contact tracing efforts, enhancing laboratory testing capabilities, and ensuring hospitals are prepared for potential cases. This announcement follows a rapid deployment of medical personnel to the outbreak's epicenter in eastern DRC.
The World Health Organization (WHO) recently declared the situation a public health emergency, prompted by fears of wider transmission after two cases were confirmed in neighboring Uganda. The outbreak, caused by the Bundibugyo strain of Ebola, has already killed more than 80 people, and there is currently no licensed vaccine for this strain.
Symptoms of Ebola Disease
The CDC says symptoms of Ebola disease may appear two to 21 days after contact with the virus, with most people showing signs eight to 10 days after exposure. Initially, symptoms are generic and are known as "dry" symptoms, which include:
- Fever
- Aches and pains in the muscles and joints
- Severe headache
- Weakness and fatigue
- Sore throat
After four to five days of illness, patients can progress to "wet" symptoms as they become sicker. These include:
- Loss of appetite
- Unexplained bleeding
- Gastrointestinal symptoms such as nausea, abdominal pain, diarrhea, and vomiting
Other symptoms may include chest pain, shortness of breath, confusion, red eyes, skin rash, hiccups, and seizures.
