Louisiana state health officials are investigating a confirmed case of measles in New Orleans. The disease was confirmed by laboratory tests in New Orleans that had recently left the country. This case does not refer to a positive measles case reported in April this year. In both cases, the subjects were not vaccinated.
"It may take between 1
0 and 21 days for a person to come into contact with anyone with measles to develop symptoms, we are over 21 days since the last reported case, so we are confident that the two Cases are not related, "said Dr. Parham Jaberi, Assistant State Health Officer. "Besides, we do not believe that the two individuals came in contact with confirmed measles because of our observation."
According to the CDC, the symptoms of measles generally occur after about seven to 14 days after a person becomes infected.
Measles typically start with high fever, cough, runny nose, and red, watery eyes. Two or three days after onset of symptoms, tiny white patches (Koplik patches) may form in a patient's mouth.
Three to five days after the onset of symptoms, a rash breaks out. It usually begins as flat red patches that appear on the face on the hairline and spread to the nape, torso, arms, legs and lining. Small raised bumps may also appear on the flat red spots. The dots can connect with each other as they spread from the head to the rest of the body. When the rash occurs, a person's fever can rise to over 104 degrees Fahrenheit.
After a few days, the fever subsides and the rash fades.
It can take between 10 and 21 days for a person to come into contact with someone with measles to develop symptoms. These typically start with a high fever, cough, runny nose, and red, watery eyes, followed by a rash that typically spreads from the head to the rest of the body. In some cases, tiny white spots may appear in the mouth two to three days after the onset of symptoms. Common complications of measles are ear infections and diarrhea, which are seen in about 10 percent of patients.
A person is contagious four days before the onset of rash and four days after the onset of rash. The highly contagious virus easily spreads through coughing, sneezing or even in the same room with an infected person.
Because there is no cure, the treatment is aimed at alleviating the symptoms. Breast breaks, antipyretics, fluids, vitamin A supplements, and the use of a humidifier are often recommended
Health authorities declared eradication of measles in the US in 2000, but it is still prevalent in other parts of the world 
If you have symptoms, you should stay at home, insulate as much as possible, and immediately contact your family doctor.
The best protection and way to prevent measles is to use two doses of measles, mumps and rubella vaccine, known as MMR. Two doses are about 97 percent effective against measles. If you are unsure about your vaccination protocols, contact your family doctor. Even a single dose of MMR for up to 72 hours after exposure to a person with measles can prevent this or greatly reduce the symptoms.
