A CNS infection is an infection which involves the central nervous system in some way. Meningitis is one of the most common and well known types, involving the meninges, the coverings of the brain and spinal cord. Other types of infections involve the brain or spinal cord directly. For example, a cerebral abscess is a bacterial brain infection and encephalitis is typically a viral infection of the brain. In general, an infection is a disease caused by the invasion of a disease-causing micro-organism or virus.
Nahuatl is an Uto-Aztecan language spoken by about 1.5 million people in Mexico. The majority of speakers live in central Mexico, particularly in Puebla, Veracruz, Hildago, San Luis Potosi, Guerrero, Mexico (state), El Distrito Federal, Tlaxcala, Morelos and Oaxaca, and also in El Salvador.lassical Nahuatl was the language of the Aztec empire and was used as a lingua franca in much of Mesoamerica from the 7th century AD until the Spanish conquest in the 16th century. The modern dialects of Nahuatl spoken in the Valley of Mexico are closest to Classical Nahuatl.
Although there are still speakers of Nahuatl, it is probably safe to say that all but the most elderly among them are bilingual in Spanish, and in general, later Nahuatl shows influence of Spanish as well as a continuing evolution of trends that were already going on in early Nahuatl.ecause a knowledge Nahuatl was so important to the early Spanish, it was an object of scholarly concern already by the mid-XVIth century. Accordingly we have a long record of it, and in some ways this makes it one of the most interesting of the indigenous American languages to study.
