Twenty-five years after the disease was declared “eliminated” in the U.S., cases are rising again, with a Texas outbreak now spreading to New Mexico. Measles cases continue to rise in the United States nearly two and a half decades after the virus had been declared eliminated in the country.

With spring break travel plans on the horizon, authorities and officials at both popular tourist destinations want people to be alert and prepared

Measles cases popping up across the United States, including an outbreak in Texas that has led to the death of a child, are prompting questions about where exactly the illness has been detected.Measles is one of the most contagious infectious diseases,

Before the invention of vaccination, which helped eliminate the disease in the US, almost everyone in childhood got measles. Not only that, but, 400 to 500 children had also died from the same each year.

A hospital in Texas on Wednesday confirmed the death of an unvaccinated child who was infected with measles—the first fatality in a two-state measles outbreak that began in January, according to the Associated Press.

Measles is highly contagious. Without a vaccine, 9 out of 10 people exposed to measles will become infected, the CDC said. About 1 to 3 of every 1,000 children with measles will die, usually from pneumonia or neurologic complications.

A few days after symptoms begin, an infected person may experience further symptoms. These may include a telltale rash, which breaks out as flat red spots on the face and then spreads down the neck and rest of the body, or koplik spots − tiny, white spots that appear inside the mouth.
