26. Multi-country Monkeypox Outbreak in Non-endemic Countries
ā Previous cases in non-endemic areas are associated with travel
ā From May 13 ā 21, 2022, 92 laboratory conļ¬rmed and 28 suspect Monkeypox cases were
reported from 12 non-endemic countries to the WHO
ā No death reported.
ā Majority have been reported amongst men who have sex with men (MSM) seeking care in
primary care and sexual health clinics.
ā All laboratory conļ¬rmed cases were detected with West African clade.
ā No established travel links to an endemic area and have presented through primary care,
secondary care or sexual health services
ā The identiļ¬cation of conļ¬rmed and suspect cases with no direct travel links to an endemic
area is atypical
27. WHO Risk Assessment
Actions taken:
ā Ongoing epidemiologic investigation and genomic sequencing to confirm the particular monkeypox virus
clade(s)
ā Vaccination, where available, provided to manage close contacts
WHO Risk assessment:
ā Infection in non-endemic countries seems to have been locally acquired with circulation occurring amongst
MSM.
ā The extent of local transmission is unclear at this stage and there is the high likelihood of identification of
further cases with unidentified chains of transmission.
ā With three countries reporting cases of monkeypox in this population group within a few days, it is therefore
highly likely that other countries may find similar situations.
WHO Advice:
ā Intensive public health measures should continue in countries reporting cases.
ā Further spread in other Member States is likely, thus, any patient with suspected monkeypox should be
investigated and isolated during the presumed and known infectious periods, that is during the prodromal
and rash stages of the illness, respectively.
30. Case Deļ¬nition: Monkeypox in Non-endemic Countries
Suspected
Case
A person of any age presenting with an unexplained acute rash
AND
One or more of the following signs or symptoms:
ā Headache;
ā Acute onset of fever (>38.5Ā°C);
ā Myalgia;
ā Back pain;
ā Asthenia;
ā Lymphadenopathy; AND
For which the following common causes of acute rash do not explain the clinical picture: varicella zoster,
herpes zoster, measles, herpes simplex, bacterial skin infections, disseminated gonococcal infection, primary
or secondary syphilis, chancroid, lymphogranuloma venereum, granuloma inguinale, molluscum contagiosum,
allergic reaction (e.g., to plants); and any other locally relevant common causes of papular or vesicular rash.
As per WHO, it is not necessary to obtain negative laboratory results for listed common causes of
rash illness in order to classify a case as suspected.

RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Etiology
ā¢ Monkeypox is a pox diseases of nonhuman primates
similar to variola in man
ā¢ MP is a zoonotic disease
ā¢ Belongs to Genus Orthopoxvirus related to variola
(smallpox) vaccinia,cowpox,buļ¬alo pox and camelpox
viruses .
ā¢ Old , new world monkeys and arthropod apes can be
aļ¬ected
68
69. 69
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Etiology
ā¢ It was also isolated from wild squirrel
(Funisciurus anerythrus )Zaire/ Congo in 1986
ā¢ The natural reservoir of monkeypox remains
unknown;however,African rodents and
primates may harbor the virus and infect
people
69
70. 70
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Monkeypox
ā¢ 1959- the ļ¬rst known outbreak in monkeys
was reported at the Statens Seruminstitut
Copenhagen/Denmark
ā¢ 1976- additional outbreaks in captive
primates have occurred in Paris
70
71. 71
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Virus
ā¢ It is rectangular virus of typical pox virus
structure and of 200 to 250 nano meter size
ā¢ Resistant to ether and relatively resistant to
cold
71
72. 72
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
ā¢ Monkeypox is endemic in the African tropical
rain forest particularly in Congo,Zaire ,West
and Central Africa
ā¢ The virus has repeatedly caused human
infections
72
73. 73
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Transmission
ā¢ The monkeypox virus can be transmitted to
humans in bites from animals ,aerosols or by
direct contact with lesions ,blood or body
ļ¬uids from an infected persons or animals .
ā¢ Most cases are zoonotic and occur after
contact with infected animal
ā¢ Can be spread on fomites
73
74. 74
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Transmission
ā¢ Aerogenous transmission is considered to be the main
route of transmission between nonhuman primates and
probably also to other species like man or as in one case in
ant eaters (Myrmecophaga tridactyla)
ā¢ The route of transmission in animals is less well
understood . The virus maybe transmitted through
aerosols through skin abrasions or by the ingestions of
infected tissues /meat
74
75. 75
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Pathogenicity
ā¢ Initial multiplication of the monkey pox virus
occurs in local cellular components ,most
probably in ļ¬xed or wandering connective
tissue cells
ā¢ In experimentally infected Macacca
fascicularis a constant viremia appeared
between the 23rd
and 4th
day P.I.
75
76. 76
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
NHP : Diļ¬erences exist in the susceptibility of
the diļ¬erent host species. Anthropod apes are
usually more severely aļ¬ected than monkeys ,
while cynomolgus monkeys suļ¬er more than
rhesus monkeys.
ā¢ After an incubation period of usually 3 to 4
days a sharp temperature rise heralds the
onset of the disease .
76
77. 77
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
ā¢ Animals become anxious with older ones
ā¢ Aggressive
ā¢ Anorexia
ā¢ With behavioral abnormalities such:
- sucking on ļ¬ngers
- inļ¬ammation of the lips
77
78. 78
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
As to development of the pocks (sores) two
types of lesions can be distinguished:
1st
type of lesion
ā¢ Acute marked facial edema
ā¢ Ulceration in mucous membranes and
papule formation
78
79. 79
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
1st
type of lesion
ā¢ General lymphadenopathy ,respiratory distress
ā¢ Death from asphyxia
ā¢ Arthropod apes are especially prone to such
severe infection (chimps,gorilla
orangutan,bonobo)
79
80. 80
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
2nd
type of lesion
ā¢ Infection occurs as a benign cutaneous eruption
ā¢ 7-8 days after experimental infection itching and
vesicular exanthema are common
ā¢ Occasional coughing and mucopurulent nasal
discharge indicate the presence of early lesions in
the respiratory tract
80
81. 81
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical symptoms
2nd
type of lesion
ā¢ Ist typical pocks appears as papules of 1 to 4 mm.in
diameter
ā¢ Develop into pustules containing thick purulent
material
ā¢ Vesicles become umbilicated & covered by crusts or
scabs
ā¢ Desquamation of scabs or crusts within 7 to 10 days
& small scars remain
81
82. 82
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Clinical Symptoms
Most common sites of pocks/sore formation in monkeys
ā¢ Buttocks
ā¢ Hands
ā¢ Feet
ā¢ Mucous membrane of the tongue

ā¢ Prevention of secondary infection using
antibiotics in NHP
ā¢ Endangered animals can be protected/useful by
variola āvaccination
85
86. 86
RESEARCH INSTITUTE FOR TROPICAL MEDICINE
Way Forward
ā¢ Avoiding contact with infected animals ( dead or sick animals).
ā¢ Avoiding contact with bedding and other materials contaminated
with the virus.
ā¢ Washing your hands with soap and water after coming into
contact with an infected animal.
ā¢ Cook foods thoroughly that contains animal meat or parts .
ā¢ Avoid contact with people who may be infected with the virus.
ā¢ PPE when caring for people or animals infected with the virus.
ā¢ Shipment of rats and NHP shall be strictly monitored by
DA-BAI,DENR and BOC for animals with MP symptoms.
