Marburg virus disease (see Viral Hemorrhagic Fevers)
Condition	Isolation	Duration of Isolation	Comment
included in hemorrhagic fevers

Measles
Condition	Isolation	Duration of Isolation	Comment
(Rubeola), all presentations	Airborne	Until 4 days after onset of rash; duration of illness in immune compromised	Immediately contact HEIP. Susceptible heatlhcare personnel (HCP) should not enter room if immune HCP are available, regardless of presumptive evidence of immunity. HCP should use respiratory protection that is at least as protective as a fit-tested N95 respirator upon entry into the care area. Additional resources, including for testing, are available on the measles web page.

Meloidosis, all forms
Condition	Isolation	Duration of Isolation	Comment
(Burkholderia (Pseudomonas) pseudomallei)	Standard		Notify the Microbiology laboratory when submitting specimens for culture from patients known or suspected to have this disease (353-1268)

Meningitis
Condition	Isolation	Duration of Isolation	Comment
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
Aseptic (non-bacterial or viral [except varicella zoster*] meningitis; also see enterovirus)	Standard
Bacterial, gram negative enteric, in neonates	Standard
Fungal**	Standard		**Alert the Microbiology Laboratory (353-1268) prior to submitting specimens for culture from patients with suspected or confirmed Coccidiodes meningitis
Haemophilus influenzae (known or suspected)	Standard	Until 24 hrs after initiation of effective therapy

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 Novel Respiratory Contact Eye Protection Standard		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.

Mucormycosis
Condition	Isolation	Duration of Isolation	Comment
	Standard

Multidrug resistant organisms (MDROs)
Condition	Isolation	Duration of Isolation	Comment
Enterococcus, vancomycin resistant (VRE)	Standard		If drainage cannot be contained by dressing, add Contact + Standard Isolation
Enteric Gram negative organisms: Acinetobacter spp. (CP-gene positive), Pseudomonas aeruginosa (CP-gene positive or cefepime or ceftazidime resistant), carbapenem resistant Enterobacteriaciae CRE (see CRE section)	Contact Standard	Duration of hospitalization and upon readmission.	Discontinuation will be determined by Infection Prevention on a case by case basis. If at least 6 months have passed since last positive culture, the patient may qualify for removal of the MDRO flag. Please contact the Infection Prevention Department to discuss.
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.

Mumps (infectious parotitis)
Condition	Isolation	Duration of Isolation	Comment
	Droplet Standard	Until 5 days after the onset of swelling	Susceptible HCWs should not provide care if immune caregivers are available. HCWs should use masks regardless of immune status.
