The Joint Director of Health Services in Dibrugarh district, Dr Udayan
Kumar Baruah on Thursday [28 Jun 2018] claimed that there are only 2
villages which are highly Japanese encephalitis (JE) sensitive.

"We want to clarify that in Dibrugarh, only 2 villages are highly JE
sensitive. So far, 35 cases of Japanese encephalitis have been
reported from Dibrugarh district, and only 4 persons died of JE," said
Dr Baruah.

He also said that from January this year [2018], they have detected 84
cases of acute encephalitis syndrome (AES) and the deaths of 13
people.

"We are doing fogging where the JE cases have mostly been detected.
Fogging is very costly, and fogging cannot fully control JE. People
should keep their houses clean. We are conducting awareness camps on
JE to control the disease. Vector-borne diseases take place during
monsoon, so everybody should keep their surroundings clean," the Joint
Director of Health Services said.

Dr Baruah added that they are taking all precautionary measures to
control JE by conducting awareness camps at the village level. "We are
doing fogging in block levels. Every year, the highest cases of JE are
reported from Naharoni," Dr Baruah said.

[The number of AES and Japanese encephalitis cases is increasing in
Assam during this monsoon season. Both JE and AES cases are reported
in northeastern India, including Assam state every year. As is often
the case, a minority of AES cases are due to JEV infections. The
etiology of AES has been unclear but debated in the past decade. It is
odd that no mention is made of JE vaccination in the report above,
which would be more effective at preventing JE cases than fogging of
residences. The _Culex_ mosquitoes that transmit JE virus breed in
extensive wetlands including rice paddies.

As noted previously, a recent publication of investigations conducted
during the 2014 and 2015 AES outbreaks indicated that scrub typhus,
caused by _Orientia tsutsugamushi_, was the etiology in about 60
percent of those AES cases. In the report above, there is no mention
of scrub typhus.

As noted in many earlier posts, the determination of the etiology or
etiologies of AES has been confusing and elusive. Various etiological
agents have been proposed in recent years as responsible for AES
cases. AES has continued to be attributed to a variety of etiologies,
including Reye syndrome-like disease, possible enterovirus infection
from polluted water, heat stroke, lychee fruit consumption and scrub
typhus (_O. tsutsugamushi_). One hopes that the prospective studies on
collaboration with the USA CDC as the season for occurrence of
encephalitis cases in children progresses will provide additional
information about the etiology of AES. The JE and AES season is now
underway in northeastern India, and many cases of encephalitis in
children are likely to occur again this year (2018).
