An
outbreak
of
chikungunya
occurred
in
Central
Italy
in
the
summer
of
2017.
During
the
outbreak,
two
siblings
with
fever
and
joint
pain
developed
a
morbilliform
skin
rash
with
prominent
involvement
of
the
palms.
Knowledge
of
the
characteristics
of
chikungunya
exanthem
is
important
to
adddress
clinical
diagnosis.

A
21
year
old
man
living
in
Rome
presented,
on
August
26,
2017,
with
a
two-day
history
of
high
fever
(39.6
C),
malaise,
joint
pain,
and
a
morbilliform
skin
rash.
The
skin
rash
affected
the
face,
trunk,
upper
limbs,
and
lower
limbs
(Fig.
1).
Weak nes s
and
joint
pain
(ankles
and
wrists
were
slightly
swollen)
lasted
for
over
two
months
after
recovery
from
the
acute
disease.
His
sister,
a
15
year
old
girl,
developed
the
same
symptoms
with
fever
onset
(38
C)
on
August
25.
The
rash
developed
on
the
2nd
day.
Joint
pain
affected
the
wrists,
which
appeared
swollen,
lasting
for
two
months
after
acute
disease
onset.
The
exanthema
involved
the
palm
of
the
hands,
particularly
the
fingertips,
which
were
intensively
flushed
in
both
patients
(Figs.
2
and
3).
Since
an
outbreak
of
chikungunya
had
been
identified
near
the
city
of
Roma,
this
diagnosis
was
hypothesized.
On
mid-September,
blood
samples
sent
to
the
Spallanzani
hospital
laboratory
in
Roma
were
positive
for
anti-chikungunya
virus
antibodies
(IgM
titer
was
1:320
and
IgG
1:640
in
both
patients).
Blood
counts
and
liver
enzymes
were
within
the
limits.
Chikungunya
is
a
vector-borne
disease,
caused
by
an
Alphavirus
transmitted
by
Aedes
spp.
mosquitoes.
In
Italy,
two
chikungunya
fever
outbreaks
occurred
in
2007
and
in
2017
[1,2].
During
the
last
outbreak,
sporadic
cases
and
small
clusters
were
reported
also
in
the
city
of
Rome
[2].
Chikungunya
fever
is
characterized
by
fever,
prominent
and
sometimes
long-lasting
joint
pain,
and
a
generalized
maculo-papular
skin
rash.
Differently
from
measles,
after
an
initial
facial
flushing,
the
face
is
often
spared
by
the
exanthema.
Palm
involvement
is
not
pathognomonic
of
chikungunya
fever,
and
has
been
described
also
in
other
alphavirus
fevers,
such
as
Mayaro
and
Ross
River
disease
[3,4].
In
conclusion,
a
diagnosis
of
chikungunya
fever
should
be
considered
when
cases
of
fever
with
joint
pain,
accompanied
by
a
skin
rash,
which
may
involve
the
palm
of
the
hands,
occur
during
the
hot
season
in
areas
with
presence
of
Aedes
spp.
mosquitoes.
