The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on ...the clinical, epidemiological and virological characteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)

Updated 6 September 2016. This guidance has been developed to provide advice on the prevention of potential sexual transmission of Zika virus. The primary transmission route of Zika virus is via the... Aedes mosquito. However, sexual transmission of Zika virus may also be possible, with limited evidence recorded in a few cases. This is of concern due to an association between Zika virus infection and potential complications, including microcephaly and Guillain-Barré syndrome.

Available evidence demonstrates that direct patient contact and contact with infectious body fluids are the primary modes for Ebola virus transmission, but this is based on a limited number of studies. In this... review, the authors address what we know and what we do not know about Ebola virus transmission. They also hypothesize that Ebola viruses have the potential to be respiratory pathogens with primary respiratory spread.

The survey centering on reasons behind community resistance was conducted in Butembo in November during a time of Ebola transmission. A researcher from Catholic University of Grab...en in Butembo and collaborators at the University of Alberta in Edmonton published their findings on Sep 26 in PLOS One.
To spark focus group discussions, the researchers used an 18-item questionnaire based on similar ones used during West Africa's outbreak in Guinea, where community resistance and episodes of violence also complicated the outbreak response.
Participants were a convenience sample of 670 adults from the region who were recruited by medical students at Catholic University of Graben. Those surveyed included clinicians, community members, and displaced persons.
