Nothing can ruin a vacation like a bout of vomiting, diarrhea, and stomach cramps. Noroviruses have become notorious for sending hundreds of cruise ship passengers at a time running for their respective bathrooms and for steering entire ships back to port early.
Back on dry land, noroviruses also have a big impact on people's health. The CDC estimates that noroviruses are responsible for more than half of all food-borne disease outbreaks each year. And noroviruses are the most common cause of diarrhea...
The disease, also known as Ebola hemorrhagic fever or Ebola virus, kills up to 90% of people who are infected.
Could There Be an Outbreak in the U.S.?
Although movies and books describe major outbreaks of Ebola-like disease in the U.S., they're just fiction. So far serious Ebola cases have only shown up in Central and West Africa.
The CDC says there’s no significant risk of Ebola in the United States. It has strong safety measures in place for people who have Ebola and are brought to the U.S. for treatment.
Ebola can spread from country to country when people travel. So it is possible for it to reach the U.S. if an infected person travels here. But there are ways to prevent people from coming to U.S. airports with the disease.
Airline crews are trained to spot the symptoms of Ebola in passengers flying from places where the virus is found. Crews are told to quarantine anyone who looks infected.
How Do You Get Ebola?
Ebola isn’t as contagious as more common viruses like colds, influenza, or measles. It spreads to people by contact with the skin or bodily fluids of an infected animal, like a monkey, chimp, or fruit bat. Then it moves from person to person the same way. Those who care for a sick person or bury someone who has died from the disease often get it.
Other ways to get Ebola include touching contaminated needles or surfaces.
You can’t get Ebola from air, water, or food. A person who has Ebola but has no symptoms can’t spread the disease, either.
What Are the Symptoms of Ebola?
Early on, Ebola can feel like the flu or other illnesses. Symptoms show up 2 to 21 days after infection and usually include:
Joint and muscle aches
Lack of appetite
As the disease gets worse, it causes bleeding inside the body, as well as from the eyes, ears, and nose. Some people will vomit or cough up blood, have bloody diarrhea, and get a rash.
How Is Ebola Diagnosed?
Sometimes it's hard to tell if a person has Ebola from the symptoms alone. Doctors may test to rule out other diseases like cholera or malaria.
Tests of blood and tissues also can diagnose Ebola.
If you have Ebola, you’ll be isolated from the public immediately to prevent the spread.
