| In the laboratory setting, non-human primates
pose a real potential for exposure of personnel to zoonotic diseases.
Although transmission of zoonotic diseases from non-human primates
to humans is rare, laboratory personnel and animal care staff are
at risk due to animal exposure. Serious injury from bites and scratches
can occur. These types of injuries/exposures can be avoided if personnel
are properly trained prior to beginning any type of work with non-human
primates. Staff working with non-human primate tissue should also
receive first-aid training in the event of a needlestick or injury
from a surgical/procedural instrument.
Non-human
primates are highly susceptible to human diseases, such as influenza,
measles and tuberculosis. Personnel working with primates
must be TB tested prior to working with non-human primates and
re-tested annually. Any individual who is experiencing cold/flu
symptoms or has active herpes simplex lesions (e.g. cold sore
) should avoid going into non-human primate areas until their
symptoms have resolved.

RECOMMENDED PREVENTIVE MEASURES
- Require a TB test annually for all staff working with non-human primates;
- Only trained personnel should handle monkeys. Handling and restraint
training can be scheduled through LARC;
- Follow posted Personal Protective Clothing requirements;
- Wash hands after handling animals or related equipment;
- Never wear protective clothing outside the animal areas;
- When seeking medical advice for any illness, inform your physician
that you work with non-human primates.
- Soiled lab coats and suits should be placed in the laundry receptacles;
items to be treated by commercial laundering service are handled
as BSL 2 contaminated articles.

RESPONSE TO INJURY
For any injury sustained from a macaque, (rhesus or cynomolgus
monkeys) or related equipment follow the Post-exposure
to B-virus First Aid protocol attached.
For all other injuries from other species of monkeys:
- Wash any injured site with soap and water for at least 15 minutes;
- Control bleeding by applying direct pressure with a sterile gauze
or bandage;
- Cover wound with clean bandage (do not apply ointment or spray);
- Seek advice from emergency room physician.

INFECTIOUS DISEASES
Cercopithicine herpesvirus type 1: See handout entitled
Occupational Health and Safety Information for Staff
With Substantial Contact With Macaques.
Tuberculosis:
This disease may be transmitted to people through contact with
birds, livestock, and non-human primates. Routine TB testing
is performed on all UCSF non-human primates.
- Reservoir/source
of infection to people: Mycobacterium spp. may be transmitted
to non-human primates (old world primates are particularly
susceptible) from humans which can be a source of infection
to other people and monkeys;
- Transmission:
Tuberculosis is usually transmitted by the aerosolization
of infective bacilli which can be found in the sputum as well
as other body fluids. Contact with body fluids during necropsy
may be a major mode of transmission to humans;
- Disease
in people: Pulmonary tuberculosis is the most common type
but other organs may also be involved.
Shigellosis:
This is a relatively common zoonotic disease that must be differentiated
from salmonellosis, campylobacteriosis and other enteric diseases.
- Reservoir/source
of infection to people: Humans are the main reservoir of disease
but like tuberculosis, infected monkeys can be a source of
infection. Any non-human primate may harbor Shigella
bacteria, and clinical signs may not be apparent;
- Transmission: fecal/oral;
- Disease in people: Diarrhea, may be with blood or mucus.
Salmonella:
-
Reservoir/source to people: Non-human primates, dogs, cats,
birds, reptiles (especially iguanas and turtles), and wild
rodents;
- Transmission: fecal/oral;
- Disease in people: Gastrointestinal disease, can be febrile with septicemia.
Cryptosporidium:
Protozoal organism that is common in mammals, particularly younger
animals.
- Reservoir/source of infection: Many mammals;
- Transmission: Fecal/oral;
- Disease in people: Self-limiting diarrhea except in immune compromised
people where it can be quite severe. No treatment.
Giardia: This protozoan is found in many mammals.
- Reservoir/source: non-human primates, other mammals, standing water;
- Transmission: Fecal/oral;
- Disease in people: Diarrhea +/- other systemic signs such as severe
cramping and nausea/vomiting.
There are
several viruses associated with non-human primates that can
cause significant disease in people. These include the Hemorrhagic
Fever Viruses, Filoviruses and Monkey
Pox Viruses. These are usually associated with recently
imported, wild-caught animals in quarantine, but are very rare
in domestically bred animals. These viruses can cause fatal
diseases in people.

ALLERGIES
General animal related allergies are common. Although there
are no known allergens associated with monkeys, the non-human
primate environment may have common allergens present such as
dust from bedding.
Note:
There are numerous viruses associated with primates which have
unknown or uncertain pathogenic potential. Examples include:
- SIV and STLV - simian counterparts to HIV,
HTLV
- Foamy agent and various other simian viruses,
e.g., SV5, SV40, etc.
- Herpesviruses saimiri (squirrels),
tamarinus (tamarinds), etc.
These may be progenitors of human viruses and their role in
human illness is unknown at this time.
