Listeria monocytogenes	Standard
Neisseria meningitidis (known or suspected)	Droplet Standard	Until 24 hrs after initiation of effective therapy
Pneumococcal (Streptococcus pneumoniae)	Standard
Tuberculosis***	Standard		***Patient should be examined for evidence of current (active) pulmonary tuberculosis. If evidence exists, see Tuberculosis below for additional isolations.
Other diagnosed bacterial	Standard
Varicella, disseminated (e.g., meningitis + rash)	Airborne
Unknown etiology	Droplet Standard	Until etiology is determined or Neisseria meningitidis is ruled out

Metapneumovirus
Condition	Isolation	Duration of Isolation	Comment
	Contact Droplet	Adult and Pediatric hematology/oncology/BMT patients: Duration of illness AND retest is negative. All other patients: Duration of illness

Middle East Respiratory Virus (MERS)
Condition	Isolation	Duration of Isolation	Comment
	Airborne Contact Droplet		Immediately contact HEIP

Molluscum contagiosum
Condition	Isolation	Duration of Isolation	Comment
	Standard

Mpox
Condition	Isolation	Duration of Isolation	Comment
	Novel Respiratory Standard	Please continue isolation until the case is discussed with Infection Prevention. Isolation will be needed until lesions have crusted, those crusts have separated, and a fresh layer of healthy skin has formed underneath.	Immediately contact HEIP. Refer to the UCSF Mpox Tip Sheet. Additional resources, including for testing, are available on the Mpox web page.

Staphylococcus aureus, nafcillin / methicillin resistant	Standard
Staphylococcus aureus, vancomycin intermediate/resistant	Contact Standard	Duration of hospitalization and upon readmission.	Discontinuation will be determined by Infection Prevention on a case by case basis.
Carbapenem Resistant Acinetobacter- carbapenemase gene positive	Contact	Duration of hospitalization and upon readmission.	Isolation may not be removed. The following carbapenemase genes are tested: KPC, NDM, OXA-48, VIM, IMP-1.
Carbapenem, cefepime or ceftazidime resistant Pseudomonas aeruginosa- carbapenemase gene positive	Contact	Duration of hospitalization and upon readmission.	Isolation may not be removed. The following carbapenemase genes are tested: KPC, NDM, OXA-48, VIM, IMP-1.
ESBL producer and carbapenemase gene positive	Contact	Duration of hospitalization and upon readmission.	Isolation may not be removed. The following carbapenemase genes are tested: KPC, NDM, OXA-48, VIM, IMP-1.
