Airborne precautions are used with measles, since measles is highly contagious. The virus can remain in the air for up to 2 hours if an infected person sneezes or coughs. The client should be placed in a negative pressure room to minimize the risk of spreading the infection. All clients are placed on universal precautions. Droplet precautions are used with infections that do not usually travel farther than 3 feet from the client. Examples of illnesses requiring droplet precautions include influenza, pneumonia, and bacterial meningitis. Droplet precautions are not adequate for the measles. There is no such thing as hazmat precautions. Contact precautions are used with infections that are transmitted by direct contact, such as C. diff and MRSA.
