An Approach of Acute Encephalitis Syndrome in Muzaffarpur, Bihar; A Different Perspective | Chapter 13 | Innovations in Medicine and Medical Research Vol.2
Acute
encephalitis syndrome (AES) is a disease characterized by fever and mental
confusion, disorientation, delirium, or coma. It could be due to various causes
such as viruses, bacteria, fungus, parasites, spirochetes, chemical, and
toxins. This chapter is an outcome of an Epidemiological investigation of AES
occurred in Muzaffarpur, Bihar in 2011 which was done by a team consisting of
experts from various disciplines. The team visited Muzaffarpur, from 14th to
20th July 2011 and reviewed the situation of deaths among children due to AES,
as directed by the Authorities. A total of 147 cases of fever with altered
sensorium were admitted between 11th June to 18th July 2011 in a private
hospital and a Medical College Hospital of Muzaffarpur. Out of these, 54 patients
died indicating case fatality rate of 36.73%. Clinico-epidemiological and
environmental evidence supports the diagnosis of Acute Encephalitis Syndrome
which has significant mortality, affecting predominantly rural population with
poor sanitation and presence of wild rats. No significant association of litchi
consumption and poor nutritional status of children with AES disease were
found. Evidences suggest that there were increased chances of contacts between
cases and wild rats during the period of occurrence of outbreak. Key
observation was the sudden drop in incidence of cases with rainfall as during
and just after the rain children abandons the outdoor games in farmlands/
litchi gardens due to accumulation of water in these areas and exposure from
the rodents prevented Etiological agent could not be identified by laboratory
tests. Time, place and person distribution of cases is suggestive of infectious
disease of short incubation period (<1 day) having wider spectrum of sub
clinical and clinical phases & lifelong immunity after first infection.
