Whether pediatric encephalitis is contagious or not is related to the specific type, as it is broad in scope and may be caused by a variety of pathogens such as viruses, bacteria, fungi, and parasites. For example, epidemic B encephalitis is clearly contagious and is mostly transmitted acutely through mosquito bites and cross-contamination among children, but with the use of vaccines it is now less common; tuberculous meningitis is mainly transmitted through the respiratory tract, and children can become infected after inhaling droplets or dust with tuberculosis bacteria, while others such as transmission through the skin or placenta are rare.
