§5199. Appendix A.

This appendix contains a list of diseases and pathogens which are to be considered aerosol transmissible pathogens or diseases for the purpose of Section 5199. Employers are required to provide the protections required by Section 5199 according to whether the disease or pathogen requires airborne infection isolation or droplet precautions as indicated by the two lists below.
Diseases/Pathogens Requiring Airborne Infection Isolation
Aerosolizable spore-containing powder or other substance that is capable of causing serious human disease, e.g. Anthrax/Bacillus anthracis
Avian influenza/Avian influenza A viruses (strains capable of causing serious disease in humans)
Varicella disease (chickenpox, shingles)/Varicella zoster and Herpes zoster viruses, disseminated disease in any patient. Localized disease in immunocompromised patient until disseminated infection ruled out
Measles (rubeola)/Measles virus
Monkeypox/Monkeypox virus
Novel or unknown pathogens
Severe acute respiratory syndrome (SARS)
Smallpox (variola)/Varioloa virus
Tuberculosis (TB)/Mycobacterium tuberculosis - Extrapulmonary, draining lesion; Pulmonary or laryngeal disease, confirmed; Pulmonary or laryngeal disease, suspected
Any other disease for which public health guidelines recommend airborne infection isolation
Diseases/Pathogens Requiring Droplet Precautions
Diphtheria pharyngeal
Epiglottitis, due toHaemophilus influenzaetype b
Haemophilus influenzaeSerotype b (Hib) disease/Haemophilus influenzaeserotype b - Infants and children
Influenza, human (typical seasonal variations)/influenza viruses
Haemophilus influenzae, type b known or suspected
Neisseria meningitidis(meningococcal) known or suspected
Meningococcal disease sepsis, pneumonia (see also meningitis)
Mumps (infectious parotitis)/Mumps virus
Mycoplasmal pneumonia
Parvovirus B19 infection (erythema infectiosum)
Pertussis (whooping cough)
Pharyngitis in infants and young children/Adenovirus, Orthomyxoviridae, Epstein-Barr virus, Herpes simplex virus, Pneumonia
Haemophilus influenzae Serotype b, infants and children
Mycoplasma, primary atypical
Streptococcus Group A
Pneumonic plague/Yersinia pestis
Rubella virus infection (German measles)/Rubella virus
Severe acute respiratory syndrome (SARS)
Streptococcal disease (group A streptococcus)
Skin, wound or burn, Major
Pharyngitis in infants and young children
Scarlet fever in infants and young children
Serious invasive disease
Viral hemorrhagic fevers due to Lassa, Ebola, Marburg, Crimean-Congo fever viruses (airborne infection isolation and respirator use may be required for aerosol-generating procedures)
Any other disease for which public health guidelines recommend droplet precautions
