Abstract
INTRODUCTION Supplementary immunization activities (SIAs) aim to interrupt measles transmission by reaching susceptible children, including children who have not received the recommended two routine doses of MCV before the SIA. However, both strategies may miss the same children if vaccine doses are highly correlated. How well SIAs reach children missed by routine immunization is a key metric in assessing the added value of SIAs. METHODS Children aged 9 months to younger than 5 years were enrolled in cross-sectional household serosurveys conducted in five districts in India following the 2017-2019 measles-rubella (MR) SIA. History of measles containing vaccine (MCV) through routine services or SIA was obtained from documents and verbal recall. Receipt of a first or second MCV dose during the SIA was categorized as "added value" of the SIA in reaching un- and under-vaccinated children. RESULTS A total of 1,675 children were enrolled in these post-SIA surveys. The percentage of children receiving a 1st or 2nd dose through the SIA ranged from 12.8% in Thiruvananthapuram District to 48.6% in Dibrugarh District. Although the number of zero-dose children prior to the SIA was small in most sites, the proportion reached by the SIA ranged from 45.8% in Thiruvananthapuram District to 94.9% in Dibrugarh District. Fewer than 7% of children remained measles zero-dose after the MR SIA (range: 1.1-6.4%) compared to up to 28% before the SIA (range: 7.3-28.1%). DISCUSSION We demonstrated the MR SIA provided considerable added value in terms of measles vaccination coverage, although there was variability across districts due to differences in routine and SIA coverage, and which children were reached by the SIA. Metrics evaluating the added value of an SIA can help to inform the design of vaccination strategies to better reach zero-dose or undervaccinated children.

Abstract
We investigated an increase in malaria deaths in order to formulate control measures. A search of records in health care facilities for cases of death following fever, with a blood smear or rapid antigen test positive for Plasmodium falciparum, identified 77 fatalities. Of these, 72 (93%) occurred in hospitals (78% of which in the 24 hours following admission). Of 60 family members of the patients who died interviewed, 70% reported that the patient had received care from unqualified rural private practitioners available round the clock. Among 100 of these rural practitioners assessed, 21% knew anti-malarial dosage and 7% knew malaria severity criteria. There were 65% and 42% vacancies among 240 community health worker and 12 microscopist positions, respectively, in the public sector in the area. As a result, the mean interval between active case search rounds in the community was 35 days (standard: 14) and the median time between blood slide collection and radical treatment was 12 days (standard < 2 days). Deficiencies in the public health system may have led to a shift towards rural practitioners. Poor management of malaria may have contributed to deaths. We posted microscopists and community health workers in the area to restore appropriate malaria management in the public sector.

Abstract
BACKGROUND In September 2007, the Gayeshpur municipality reported a cluster of cases with diarrhoea. We aimed to identify the causative agent and the source of the disease. METHODS We defined a case as the occurrence of diarrhoea (> 3 loose stools/day) with fever or bloody stools in a resident of Gayeshpur in September-October 2007. We asked healthcare facilities to report cases, collected stool specimens from patients, constructed an epidemic curve, drew a map and calculated the incidence by age and sex. We also conducted a matched case-control study (58 in each group), calculated matched odds ratio (MOR) and population attributable fraction (PAF), as well as assessed the environment. RESULTS We identified 461 cases (attack rate: 46/1000 population) and isolated Shigella flexneri (serotype 2a and 3a) from 3 of 4 stool specimens. The attack rate was higher among females (52/1000) and those in the age group of 45-59 years (71/1000). The outbreak started on 22 September, peaked multiple times and subsided on 12 October 2007. Cases were clustered distal to a leaking pipeline that crossed an open drain to intermittently supply non-chlorinated water to taps. The 58 cases and 58 controls were matched for age and sex. Drinking tap water (MOR: 10; 95% CI: 3-32; PAF: 89%), washing utensils in tap water (MOR: 3.7; 95% CI: 1.2-11.3) and bathing in tap water (MOR: 3.5; 95% CI: 1.1-11) were associated with the illness. CONCLUSION This outbreak of diarrhoea and Shigella flexneri dysentery was caused by contamination of tap water and subsided following repair of the pipeline. We recommended regular chlorination of the water and maintenance of pipelines.

Abstract
To estimate the burden and cost of chikungunya in India, we searched for cases of fever and joint pain in the village of Mallela, Andhra Pradesh, and collected information on the demography, signs, symptoms, healthcare utilization and expenditure associated with the disease. We estimated the burden of the disease using disability-adjusted life years (DALYs). We estimated direct and indirect costs and made projections for the district and state using surveillance data corrected for under-reporting. On average, from December 2005 to April 2006, each of the 242 cases in the village led to a burden of 0.0272 DALYs (95% CI 0.0224-0.0319) and a cost of US$37.50 (95% CI 30.6-44.3). Overall, chikungunya in Mallela led to 6.57 DALYs and a loss of US$9100. Out-of-pocket direct medical costs accounted for 68% of the total. From January to December 2006 the burden for Kadapa district was 160 DALYs (cost: US$290 000). Over the same period the burden for Andhra Pradesh was 6600 DALYs (cost: US$12 400 000). While the burden was moderate, costs were high and mostly out of pocket.
