    Study Type
    Demographic Surveillance
    Series Information
    This dataset contains baseline census and 7 rounds of surveillance data covering the period from 1 Jan 2011 to 31 Dec 2015. The baseline census carried out in 2011 and first round began in mid 2012. It is important to note that this does not imply that the dataset contains 3 individual cross sectional component rather that the information (events) assosiated with each individual could have been updated at each of these 7 surveullance rounds if the individual was under surveillance during any particular round

    Overview
    Abstract
    The Kombewa Health and Demographic Surveillance System (HDSS) grew out of the Kombewa Clinical Research Centre in 2007 and has since established itself as a platform for the conduct of regulated clinical trials, nested studies and local disease surveillance. The HDSS is located in a rural part of Kisumu County, Western Kenya, and covers an area of about 369 km2 along the north-eastern shores of Lake Victoria. A dynamic cohort of 141 956 individuals drawn from 34 718 households forms the HDSS surveillance population. Following a baseline survey in 2011, the HDSS continues to monitor key population changes through routine biannual household surveys. The intervening period between set-up and baseline census was used for preparatory work, in particular Global Positioning System (GPS) mapping. Routine surveys capture information on individual and households including residency, household relationships, births, deaths, migrations (in and out) and causes of morbidity (syndromic incidence and prevalence) as well as causes of death (verbal autopsy). The Kombewa HDSS platform is used to support health research activities, that is clinical trials and epidemiological studies evaluating diseases of public health importance including malaria, HIV and global emerging infectious diseases such as dengue fever. Formal data request and proposed collaborations can be submitted at Kombewadssdata@usamru-k.org .

    Scope
    Notes
    This study represnts only a portion of the total data associated with the complete Kombewa HDSS demographic surveillance as described in the study abstract.

    It specifically only includes the events defining the resident exposure of individuals under survellance as well as the delivery events of women. Each type of event contains minimal attributes describing the event:

    Attributes common to each event:

    Event Type,

    Event Date

    Observation date

    Migration:

    Origin and Destination

    Delivery

    Live born counts

    Coverage
    Geographic Coverage
    The Kombewa HDSS is located in a rural part of Kisumu County, western Kenya, and covers an area of about 369km2 stretching along the north-eastern shores of Lake Victoria The demographic surveillance area (DSA) is about 40km west of Kisumu city, the administrative capital of Kisumu County, and borders the KEMRI/CDC HDSS to the west and northern parts. The site lies between longitudes 34024'00"E and 34041'30"E, and latitudes 0011'30" to N-0011'30"S, at an average altitude of 1400m above sea level. The area has a total of 37 subdivisions

    (sub-locations) and 359 villages based on mapping work done by the programme from 2008 to 2010

    Universe
    Residents household members of household resident within the demographic surveillance area.

    Inmigrants are defined by intention to become resident, but actual residence eposodes of less than 90 days are censored.

    Outmigrants are defind by intention to become resident elsewhere, but actual periods of non-resident less than 90 days are censored.

    Children born to resident women are considered resident by default, irrespective of actual place of birth.

    The data contains the events of all indididuals ever resident during the study period (01 Jan 2011 to 31 Dec 2015)
