The researchers found kids regularly involved in the program were in better physical shape over time. Around 6 % of the youngsters demonstrated a substantial improvement in conditioning compared with less than 1 % of the children who were not assigned to FITKids. But most memorable was the effect afternoon play experienced on daytime course performance. Before-and-after testing and brain scans showed that the youngsters enrolled in the workout program demonstrated a two-fold increase in level of accuracy on cognitive tasks.Symptoms of severe cases range from headache, high fever, neck stiffness, disorientation, coma, tremors, seizures, or paralysis, according to the CDC. Infectious-disease professional Dr. Marc Siegel, a professor of medicine at NYU Langone Medical Center in New York City, said concern with a West Nile epidemic is overblown. ‘It is by no means endemic among humans. But it occurs in areas where we have a nagging problem controlling the mosquito human population,’ he said. About the same number of cases occur each year, Siegel said. ‘It’s tied to the amount of mosquitoes,’ he stated, adding, ‘West Nile isn’t transmittable person-to-person.’ Siegel said that for many people infected with West Nile virus, it appears like a bad flu with fever, muscle and headache ache.
