The Manual for Parasitological Surveillance in Prevention of Reintroduction or Re-establishment of Malaria in Sri Lanka (2019) provides guidelines to health professionals on how to conduct effective malaria surveillance to prevent the reintroduction of the disease in Sri Lanka, which was certified m...alaria-free in 2016.
The manual outlines strategies for active and passive case detection, laboratory diagnosis, case investigation, foci investigation, and follow-up measures. It emphasizes targeted screening of high-risk populations, including travelers and migrant workers, and explains the importance of prompt reporting, accurate parasitological confirmation, and coordination between healthcare levels. The overall goal is to maintain Sri Lanka’s malaria-free status by ensuring early detection and rapid response to any imported or locally suspected malaria cases.

Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Parasites & Vectors volume 11, Article number: 264 (2018)
Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

A new survey on the impact of the floods in Pakistan on older people reveals that hundreds of lives are needlessly being put at risk due to the decimation of health services and the rise of diseases like malaria and diarrhoea, which can be killers to older people with weaker immune systems.
Climate-induced water insecurity poses one of the biggest threats to humanity and will lead to more hunger, disease and displacement
Oxfam water engineers are having to drill deeper, more expensive and harder-to-maintain water boreholes used by some of the poorest communities around the world, mo...re often now only to find dry, depleted or polluted reservoirs.
Today, during World Water Week, Oxfam publishes the first of its series of reports, “Water Dilemmas”, about the growing water crisis, in large part driven by global heating from greenhouse gas emissions. The report describes how climate change will impact water security in different regions, leading to more hunger, disease and displacement.
Carlos Calderon, Humanitarian Advocacy and Partnerships Lead for Oxfam Aotearoa said, “This new Oxfam research is focused on the global Water, Sanitation and Hygiene (WaSH) situation, but it paints a picture that illustrates the complexity of elements that, combined, will continue to increasingly affect women, girls, boys and men in the decades to come. Changing weather, poverty, inequality, gender-based violence, political instability and conflicts are impacting the availability and quality of adequate water systems. All governments, particularly those from rich countries, should responsively take action at a global scale. The clock is ticking. Our children will judge us for our actions today, or for the lack of them.”
