Based on their ability to move to other individuals, infectious diseases may also be classified as contagious. Contagious diseases are diseases that can be transmitted directly, from one individual to another - for example foot and mouth disease, influenza. Some infectious diseases are indirectly transmitted e.g. Japanese encephalitis (mosquito), babesiosis (tick), anthrax (contaminated soil). Some diseases, e.g. anthrax, influenza, and foot and mouth may be transferred both directly or indirectly.
