DALLAS — Health officials in Texas have reached out to about 80 people who may have had direct or indirect contact with the man who brought Ebola into the U.S. or someone close to him, a public-health spokeswoman said Thursday.
None of the people is showing symptoms, but health authorities have educated them about Ebola and told them to notify medical workers if they feel ill.
The group will be monitored to see if anyone seeks medical care during the three weeks immediately following the time of contact, said Erikka Neroes, of the Dallas County Health and Human Services agency.
The people include 12 to 18 who came in direct contact with the infected man, as well as others known to have had secondhand contact, she said.
“This is a big spider web” of people involved, Neroes said.
The initial group includes three members of the ambulance crew that took Thomas Eric Duncan to the hospital, plus a handful of schoolchildren.

The Texas Department of State Health Services said Thursday it has a list of about 100 possible contacts but that the official number will be lower.
Health officials are focusing on containment to try to stem the possibility of the Ebola virus spreading beyond Thomas Eric Duncan, who traveled from Liberia to Dallas to visit relatives and fell ill on Sept. 24. His sister, Mai Wureh, identified Duncan as the infected man in an interview with The Associated Press.
A Dallas emergency room sent Duncan home last week, even though he told a nurse that he had been in disease-ravaged West Africa. The decision by Texas Health Presbyterian Hospital to release Duncan could have put others at risk of exposure to Ebola before the man went back to the ER a couple of days later when his condition worsened.
The patient explained to a nurse last Thursday that he was visiting the U.S. from Africa, but that information was not widely shared, said Dr. Mark Lester, who works for the hospital’s parent company.
Hospital epidemiologist Dr. Edward Goodman said the patient had a fever and abdominal pain during his first ER visit, not the riskier symptoms of vomiting and diarrhea. Duncan was diagnosed with a low-risk infection and sent home, Lester said.
The hospital is reviewing how the situation would have been handled if all staff had been aware of the man’s circumstances.
But the diagnosis, and the hospital’s slip-up, highlighted the wider threat of Ebola, even far from Africa.
“The scrutiny just needs to be higher now,” said Dr. Rade Vukmir, a spokesman for the American College of Emergency Physicians.
Duncan has been kept in isolation at the hospital since Sunday. He was listed in serious but stable condition.
Neighbors in Monrovia, Liberia, believe Duncan become infected when he helped bundle a sick pregnant neighbor into a taxi a few weeks ago and set off with her to find treatment.
The 19-year-old woman was convulsing and complaining of stomach pain, and everyone thought her problems were related to her pregnancy, in its seventh month. No ambulance would come for her, and the group that put her in a taxi never did find a hospital. She died, and in the following weeks, all the neighbors who helped have gotten sick or died, neighbors said.
Duncan’s neighborhood, a collection of tin-roofed homes, has been ravaged by Ebola. So many people have fallen ill that neighbors are too frightened to comfort a 9-year-old girl who lost her mother to the disease.
Ebola is believed to have sickened more than 7,100 people in West Africa and killed more than 3,300, according to the World Health Organization. Liberia is one of the three countries hit hardest in the epidemic, along with Sierra Leone and Guinea.
Ebola symptoms can include fever, muscle pain, vomiting and bleeding, and can appear as long as 21 days after exposure to the virus. The disease is not contagious until symptoms begin. It spreads only by close contact with an infected person’s bodily fluids.
Duncan left Liberia on Sept. 19, flying from Brussels to Dulles Airport near Washington. He then boarded a flight for Dallas-Fort Worth, according to airlines, and arrived the next day. He started feeling ill four or five days later, Frieden said.
Since the man had no symptoms on the plane, the CDC stressed there is no risk to his fellow passengers, said Dr. Tom Kenyon, director of the CDC’s Center for Global Health.
The CDC has received 94 inquiries from states about illnesses that initially were suspected to be Ebola, but after taking travel histories and doing some other work, most were ruled out. Of the 13 people who actually underwent testing, only one — Duncan — tested positive.
Four American aid workers who became infected in West Africa have been flown back to the U.S. for treatment after they became sick. Three have recovered.
