Recent investigations into the March 2003 outbreak of SARS in Hong Kong have concluded that environmental factors played an important role in the transmission of the disease. These studies have focused on a particular outbreak event, the rapid spread of SARS throughout Amoy Gardens, a large, private apartment complex. They have demonstrated that, unlike a typical viral outbreak that is spread through person-to-person contact, the SARS virus in this case was spread primarily through the air.
Currently, the emergence of a novel human coronavirus, SARS-CoV-2, has become a global health concern causing severe respiratory tract infections in humans. Human-to-human transmissions have been described with incubation times between 2-10 days, facilitating its spread via droplets, contaminated hands or surfaces. We therefore reviewed the literature on all available information about the persistence of human and veterinary coronaviruses on inanimate surfaces as well as inactivation strategies with biocidal agents used for chemical disinfection, e.g.
Prevention and control of cholera with household and community water, sanitation and hygiene (WASH) interventions: A scoping review of current international guidelines
Introduction. Cholera remains a frequent cause of outbreaks globally, particularly in areas with inadequate water, sanitation and hygiene (WASH) services. Cholera is spread through faecaloral routes, and studies demonstrate that ingestion of Vibrio cholerae occurs from consuming contaminated food and water, contact with cholera cases and transmission from contaminated environmental point sources.
Introduction A cholera epidemic began in Haiti over 8 years ago, prompting numerous, largely quantitative research studies. Assessments of local ‘knowledge, attitudes and practices’ relevant for cholera control have relied primarily on cross-sectional surveys. The voices of affected Haitians have rarely been elevated in the scientific literature on the topic.
Background: Refugees are at high risk for communicable diseases due to overcrowding and poor water, sanitation,
and hygiene conditions. Handwashing with soap removes pathogens from hands and reduces disease risk. A
hepatitis E outbreak in the refugee camps of Maban County, South Sudan in 2012 prompted increased hygiene
promotion and improved provision of soap, handwashing stations, and latrines. We conducted a study 1 year after
After the flood: an evaluation of in-home drinking water treatment with combined flocculent-disinfectant following Tropical Storm Jeanne — Gonaives, Haiti, 2004
Tropical Storm Jeanne struck Haiti in September 2004, causing widespread flooding which contaminated water sources, displaced thousands of families and killed approximately 2,800 people. Local leaders distributed PuR, a flocculent-disinfectant product for household water treatment, to affected populations. We evaluated knowledge, attitudes, practices, and drinking water quality among a sample of PuRw recipients. We interviewed representatives of 100 households in three rural communities who received PuR and PuR-related education.
Programmatic implications for promotionof handwashing behavior in an internally displaced persons camp in North Kivu, Democratic Republic of Congo
Background: Diarrhea and acute respiratory infections (ARI) account for 30% of deaths among children displaced due to humanitarian emergencies. A wealth of evidence demonstrates that handwashing with soap prevents both diarrhea and ARI.
Pilot testing and evaluation of a toolkit for menstrual hygiene management in emergencies in three refugee camps in Northwest Tanzania
Displaced adolescent girls and women face many challenges managing their monthly menstrual flow with dignity
and comfort in various challenging settings around the world, such as refugee camps, informal settlements, and
while in transit across geographies as they flee disaster or conflict. Menstrual hygiene management requires easy
access to safe, private water and sanitation facilities, along with appropriate menstrual materials and supplies, discreet
Legal principles and moral obligations that guarantee the basic needs of people living in humanitarian crisis situations (HCSs) predate inclusive development (ID). This review of the scholarly literature on access to water, sanitation and hygiene services (WASH) in HCSs links: (a) legal principles and moral obligations for WASH in HCSs, (b) technological, assessment and participatory instruments for WASH provision in HCSs, and (c) the social, relational and environmental dimensions of ID.
Measuring the Benefits of using market based approaches to provide water and sanitation in humanitarian contexts
The use of cash transfers and market based programming (CT/MBP) to increase the efficiency and effectiveness of emergency responses is gaining prominence in the humanitarian sector. However, there is a lack of existing indicators and methodologies to monitor activities designed to strengthen water and sanitation (WaSH) markets. Gender and vulnerability markers to measure the impact of such activities on different stakeholders is also missing.
