COVID-19 vaccines have proven to be safe, ...effective and life-saving. Like all vaccines, they do not fully protect everyone who is vaccinated, and we do not yet know how well they can prevent people from transmitting the virus to others. So as well as getting vaccinated, we must also continue with other measures to fight the pandemic.

The CDC's "About Cholera" webpage provides essential information on cholera, an intestinal infection caused by the bacterium Vibrio cholerae. It highlights that cholera is primarily spread through contaminated water and food, leading to severe diarrhea, dehydration, and potentially death if untreate...d. Individuals in areas with unsafe drinking water, poor sanitation, and inadequate hygiene are at the highest risk. The page emphasizes the importance of early and proper treatment, such as rehydration therapy, to improve survival rates. Preventative measures include using treated water, practicing good hygiene, and vaccination, especially for travelers to regions where cholera is prevalent.

Leaving no one behind in the Covid-19 Pandemic: a call for urgent global action to include migrants & refugees in the Covid-19 response
People on the move, whether they are economic migrants or forcibly displaced persons such asylum seekers, refugees, and internally displa...ced persons (hereafter called migrants & refugees), should be explicitly included in the responses to the coronavirus disease 2019 pandemic. This global public health emergency brings into focus, and may exacerbate, the barriers to healthcare these populations face. Many migrant & refugee populations live in conditions where physical distancing and recommended hygiene measures are particularly challenging. The Covid-19 pandemic reveals the extent of marginalisation migrant & refugee populations face. From an enlightened self-interest perspective, the Covid-19 disease outbreak control measures will only be successful if all populations are included in the response. It is counter- productive to exclude migrant & refugee populations from the preparedness and response to the Covid-19 pandemic.

We investigate whether and to what extent Chinese development finance affects infant mortality, combining 92 demographic and health surveys (DHS) for a maximum of 53 countries and almost 55,000 sub-national locations over the 2002-2014 period. We address causality by instrumenting aid with a set of ...interacted variables. Variation over
time results from indicators that measure the availability of funding in a given year. Cross-sectional variation results from a sub-national region’s “probability to receive aid.” Controlled for this probability in tandem with fixed effects for country-years and provinces, the interactions of these variables form powerful and excludable instruments. Our results show that Chinese aid increases infant mortality at sub-national scales, but decreases mortality at the countrylevel. In several tests, we show that this stark contrast likely results from aid being fungible within recipient countries.

One approach to development assistance for health, or health aid, emphasizes the ex ante selection of cost-effective health interventions, an approach that began with the World Development Report (1993) on Investing in Health and has since been adopted by the Effective Altruism community. But just h...ow much of health aid is cost-effective? In this paper, we examine projects in the Organisation for Economic Co-operation and Development (OECD) Creditor Reporting System, the standard dataset that measures and characterizes development assistance for health, for the
years 2019 to 2021, and count the number of projects that refer to interventions from a list of highly cost-effective interventions as defined by the Disease Control Priorities Project, third edition. This exploratory quantitative analysis indicates that 61% of projects used a key word/phrase of a costeffective intervention. There were 11.9 interventions mapped per project on average. There is little evidence that donors tailor the set of interventions to country income levels by cost-effectiveness.
Policymakers may benefit from reviewing the full portfolio of interventions covered by domestic and external resources.

Zambia is facing a severe economic crisis marked by high inflation, increasing poverty and a heavy debt burden that is straining both its fiscal stability and progress in health outcomes. By 2020, the country's external debt reached United States dollars (USD) 12.7 billion, representing 108% of the ...country's gross domestic product (GDP). In 2020, Zambia sought assistance through the G20 Common Framework and the International Monetary Fund (IMF) Extended Credit Facility (ECF), securing a USD 1.7 billion loan over 5 years. IMF loans, however, come with austerity measures that prioritise fiscal discipline but could potentially exacerbate social inequalities. These measures, which include increasing consumer taxes on goods and services (value added taxes - VATs), electricity tariffs and fuel prices, disproportionately impact vulnerable populations, raising concerns about their long-term effects on essential services, especially accessible and good quality healthcare services.

The document “Malaria Prophylaxis for Travellers: Guideline for Healthcare Workers” (2019) from Sri Lanka provides guidance for healthcare providers on preventing malaria among travelers to endemic areas.
It explains that since Sri Lanka was certified malaria-free in 2016, the main risk comes f...rom imported cases, mostly Sri Lankan travelers. The document emphasizes assessing travelers’ risk, advising on mosquito bite prevention, and prescribing appropriate chemoprophylaxis like chloroquine, mefloquine, atovaquone-proguanil, or doxycycline depending on destination and traveler profile.
It highlights that children, pregnant women, and immunocompromised individuals are particularly at risk, and stresses adherence to medications and protective measures. Special instructions are given on handling missed doses, long-term prophylaxis, and managing side effects. Overall, the guideline aims to maintain Sri Lanka’s malaria-free status by preventing reintroduction through well-informed traveler care.

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.

The emergence of SARS-CoV-2 has significantly altered the epidemiology of other infectious diseases, making investigations into its co-infection with malaria particularly relevant in endemic regions. This review examines the epidemiological, incubation and clinical features of the two diseases, high...lighting the diagnostic challenges and strategies for accurate detection. Emerging immunological and genetic evidence indicates that prior exposure to malaria may reduce the severity of outcomes of SARS-CoV-2 infection through mechanisms involving ACE2 downregulation, TLR signalling, T-cell activation and upregulation of coinhibitory receptors. Additionally, potential control measures are discussed, including vaccine development, the repurposing of antimalarial drugs, the exploration of natural products, innovations in bioinsecticides, and the strengthening of electronic disease surveillance. These insights provide valuable guidance for clinical management and public health policy, while emphasising the need for continued research into the complex interactions between SARS-CoV-2 and malaria.

In 2019, 1.5 billion international tourist trips were counted worldwide. Germany, with 70.8 million vacations lasting ≥ 5 days, was one of the populations most willing to travel. These days, even elderly and multimorbid persons regularly travel long-distance, which can be associated with significa...nt health risks. By advising travelers and implementing preventive measures, the risk of illness can be reduced significantly.
