On May 23, 2017, the health authorities in Longding district, Arunachal Pradesh, India, reported four suspected measles-related deaths in Konsa village, a remote village on the Indo-Myanmar border.

We investigated to describe the epidemiology of the outbreak and identify associated risk factors.

We defined a measles case as fever and maculopapular rash with cough, coryza, or conjunctivitis in a village of Longding district resident from March 1 to June 18, 2017. In Konsa village, we conducted a retrospective cohort study of children ≤5 years. We calculated attack rate (AR), case fatality rate (CFR), measles-containing vaccine first dose (MCV1) and Vitamin A coverage, risk ratio (RR), and vaccine efficacy. We collected samples for laboratory confirmation. We conducted a routine immunization system evaluation at multiple levels of Longding district.

We identified 75 suspected cases (56% females) for a Konsa village-specific AR of 86% (75/87) among children ≤5 years; the median age was 36 months; CFR was 7% (5/75); all deaths unvaccinated; none received Vitamin A. Coverage for MCV1 was 9.2% (6/65) and Vitamin A 4.6% (3/65). No MCV1 (RR = 7.3, 95% confidence interval [CI] = 1.3-53) and participation in a recent local festival (RR = 5.3, 95% CI = 1.5-18.5) were associated with illness. MCV vaccine efficacy was 100%. Of 17 cases, 13 tested positive for measles. The local health facility had neither staff nor immunization microplans.

This outbreak was likely due to low MCV1 and Vitamin A coverage due to poor health-care access. The investigation led to a district measles catch-up campaign and resumption of regular immunization.

A suspected food-poisoning outbreak occurred in a residential school in Mirzapur, India, in February, 2017.

We investigated the outbreak to find out the epidemiology and to identify the risk factors.

A descriptive study followed by retrospective-cohort study was done to investigate the outbreak. Cases (defined as ≥3 or more loose stools in 24 h, abdominal pain, or vomiting with onset between February 1 and 4, 2017) were searched by reviewing sick/patient registers from school and nearby health facilities. Cases were also searched through active surveillance by visiting school hostels. Stool samples were sent for microbiological testing. Food sources and food handlers were also assessed.

Among 468 students, 204 cases were identified (44% attack rate) without any mortality. The median age was found to be 14 years (range 10-18 years) and 59% were male. Relative risk with consumption of curd, apple, and panjiri (sweetened wheat flour) was found to be 15.4, 2.5, and 3.7, respectively. All these three food items were served as prasad, a religious offering. Only consumption of sweetened curd (adjusted odds ratio = 36.1, 95% confidence interval = 12.1-107.8) was significantly associated with gastroenteritis. No microorganism was isolated from two tested stool samples. Curd from the vendor was prepared from nonpasteurized milk. There were no illnesses among food-handlers.

This outbreak of acute gastroenteritis in a residential school was associated with consumption of curd, likely contaminated with preformed toxins. We recommend implementation of the food safety and standards authority of India regulations.

Acute diarrheal disease (ADD) accounts for 12 million cases and 1216 deaths annually in India. On July 13, 2016, an ADD outbreak was reported from Sawargaon village from Nagpur district, Maharashtra.

The outbreak was investigated to describe the epidemiology and suggest control and preventive measures.

A case was defined as a person experiencing at least one loose stool in Sawargaon village between July 9, 2016, and July 31, 2016. We searched for cases by enhanced passive surveillance. We collected stool samples for bacterial culture and tested water from multiple water sources for fecal coliforms. We also reviewed sanitary practices and rainfall data.

A total of 889 cases were identified, with 51% female, 280 hospitalizations (31%), and two deaths. The median age was 27 years (range 6 months to 90 years). Cases started on July 9, a week after heavy rains. learn more District authorities started chlorination of water sources on July 13 and cases declined soon after. Two of nine stool samples tested positive for Vibrio cholera O1 serogroup. Of the 18 water samples collected, 16 (88%) samples from multiple sources, including wells, hand pumps, and taps, were positive for fecal coliforms. Of 1,885 households in the village, 450 (24%) households had no toilets and open defecation was commonly observed in the nearby river bed.

This ADD outbreak was likely associated with drinking contaminated groundwater, which probably occurred after heavy rainfall in an area of open defecation. We recommended providing chlorinated drinking water, promoting safe sanitation practices, including building more public and private toilets, and enhancing diagnostic laboratory capacity.

A foodborne disease outbreak among wedding attendees from Makunsar village, Palghar district, Maharashtra state, India, was reported on February 18, 2018.

The outbreak investigation was conducted to find out the epidemiology of the outbreak and to identify the etiologic agent and risk factors.

A case-control study was carried out, where cases (patients), controls, and food handlers were interviewed and leftover foods were collected for culture. A case was defined as a person having vomiting or diarrhea (i.e., ≥3 loose stools within 24 h) who attended the wedding ceremony at Makunsar village, Palghar district, Maharashtra, on February 18, 2018. Attack rate and odds ratio (OR) were calculated with 95% confidence intervals (CIs).

Out of 75 cases, 63% were female. Altogether, forty-two (56%) cases were hospitalized, and later on, all of them were discharged from hospital without any mortality. About 93%, 68%, 43%, and 41% of the cases reported with vomiting, nausea, abdominal pain, and diarrhea, respectively.
