Abstract
Introducton: Scrub typhus is an acute febrile illness
endemic to tsutsugamushi triangle including Nepal. The
WHO identfes scrub typhus as a re-emerging disease in
South-East Asia. Scrub typhus can have varied
manifestatons in children. We aimed to study clinico-
laboratory profle and therapeutc outcomes of serologically
confrmed scrub typhus in children.
Methods: A retrospectve study was conducted at Kant
Children’s Hospital, Nepal afer obtaining ethical clearance
from Insttutonal Review Commitee, and reviewing the
medical records of serologically diagnosed scrub typhus
admited to the hospital between August 2016 and January
2018. Relevant data were entered in and analyzed using
SPSS 20.0.
Results: Children from 9 districts of Nepal severely afected
by the 2015 earthquake were admited; mostly from
Dhading (14.5%) and Gorkha (9.7%) districts. All 62 children
included in the study had a fever; whereas pain abdomen,
vomitng, cough, headache, and generalized body swelling
were present in 25.8%, 21.0% 24.2%, 14.5%, and 14.5%
cases respectvely. Hepatomegaly, splenomegaly,
hepatosplenomegaly, lymphadenopathy, and rashes were
found in 53.2%, 38.7%, 32.2%, 17.7% and 9.7% cases
respectvely. Thrombocytopenia and hyponatremia were
seen in 72.6% and 28.6% cases respectvely. The
combinaton of hepatosplenomegaly and thrombocytopenia
was seen in 29.0%. Azithromycin was used as frst-line
treatment in 56 (90.3%) children while other children were
treated with doxycycline and chloramphenicol. Seven
(11.3%) children required PICU admission. The mean
duraton of hospital stay for all children was 6.95 ( ± 2.68)
days while it was 9.00 ( ± 3.51) days for children requiring
PICU admission.
Conclusions: Scrub typhus should be considered in children
with an acute febrile illness with hepatosplenomegaly and
thrombocytopenia. Azithromycin is the drug of choice.
Some children may need intensive care.

Introducton
Scrub typhus is an acute febrile illness caused by obligate
intracellular gram-negatve bacterium Orienta tsutsugamushi
transmited to rodents (primary host) and humans (accidental
host) by the bite of the larval form (chigger) of trombiculid mite
(leptotrombidium). Scrub typhus is endemic to a part of the
world known as the “tsutsugamushi triangle” which extends
from northern Japan and far-eastern Russia in the north to
northern Australia in the south and to Pakistan in the west [1].
Nepal is within the “tsutsugamushi triangle” [1]. There were a
few atempts to investgate scrub typhus in Nepal, however,
there was no clear evidence of apparent outbreak (and fatality)
of scrub typhus in Nepal before 2014. Three months afer the
devastatng earthquake in Nepal, B.P. Koirala Insttute of Health
Sciences (BPKIHS), Dharan had alerted Epidemiology and
Disease Control Division (EDCD) that children with fever and
severe respiratory features had not been responding to usual
course of treatment but later the conditon was confrmed to be
scrub typhus and thus outbreak of scrub typhus was ofcially
confrmed in Nepal in 2015 [1]. The WHO identfes scrub typhus
as a re-emerging disease in South-East Asia with a case fatality
rate up to 30% if lef untreated [2].
Scrub typhus can have varied manifestatons and can be mild
to severe in children. The disease usually presents as an acute
febrile illness with typical eschar, generalized lymphadenopathy,
rash and non-specifc symptoms such as fever, headache,
myalgia and cough [3]. The disease usually responds
dramatcally to antbiotcs but the delay in diagnosis and
initaton of appropriate treatment can result in severe
complicatons such as acute respiratory distress syndrome,
