The World Health Organization's cholera fact sheet provides essential information about cholera, an acute diarrheal infection caused by ingesting food or water contaminated with Vibrio cholerae bacteria. The disease remains a global public health threat, particularly in areas lacking safe water and ...adequate sanitation. While many infected individuals exhibit mild or no symptoms, severe cases can lead to rapid dehydration and death if untreated. Prevention focuses on ensuring access to clean water, proper sanitation, and hygiene practices. Effective treatment primarily involves prompt administration of oral rehydration solutions. The fact sheet also highlights the importance of surveillance, preparedness, and response strategies to control outbreaks.

Immunizations are an essential health service that protect susceptible individuals from vaccine-preventable diseases (VPD).2 By providing timely immunizations, individuals and communities remain protected and the likelihood of a VPD outbreak decreases, Preventing a VPD ...outbreak not only saves lives but requires fewer resources than responding to the outbreak and helps reduce burden on a health system already strained by the COVID-19 pandemic, While committing to sustaining immunization systems, countries should use approaches that respect the principle of do-no-harm and limit transmission of COVID-19 while providing immunization activities, Immunization visits can also be used as opportunities to disseminate messages to encourage behaviours to reduce transmission risk of the COVID-19 virus, to identify signs and symptoms of COVID-19 disease, and to provide guidance on what to do if symptoms emerge

The World Health Organization's malaria fact sheet provides an overview of malaria, a life-threatening disease caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes. It highlights that malaria is preventable and curable, yet remains a significant glo...bal health challenge. Key statistics from 2023 indicate an estimated 263 million malaria cases and 597,000 deaths worldwide, with the WHO African Region bearing the majority of this burden. The fact sheet details transmission methods, symptoms, at-risk populations, diagnostic approaches, treatment options—including the use of artemisinin-based combination therapies (ACTs)—and preventive measures such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS). It also discusses the impact of malaria on vulnerable groups like children under five and pregnant women, and outlines WHO's global response strategies aimed at reducing malaria incidence and mortality rates.

RESULTS: Between 76 and 97% of the PHCS offered RMCAH services before the lockdown. Except in antenatal, delivery and adolescent care, there was a decline of between 2 and 6% in all the services during the lockdown and up to 10% decline after the lockdown with variation across and within States. Dur...ing the lockdown. Full-service delivery was reported by 75.2% whereas 24.8% delivered partial services. There was a significant reduction in clients' utilization of the services during the lockdown, and the difference between States before the pandemic, during, and after the lockdown. Reported difficulties during the lockdown included stock-out of drugs (25.7%), stock-out of contraceptives (25.1%), harassment by the law enforcement agents (76.9%), and transportation difficulties (55.8%). Only 2% of the PHCs reported the availability of gowns, 18% had gloves, 90.1% had hand sanitizers, and a temperature checker was available in 94.1%. Slightly above 10% identified clients with symptoms of COVID-19.
CONCLUSIONS: The large proportion of PHCs who provided RMCAH services despite the lockdown demonstrates resilience. Considering the several difficulties reported, and the limited provision of primary protective equipment more effort by the government and non-governmental agencies is recommended to strengthen delivery of sexual and reproductive health in primary health centres in Nigeria during the pandemic.

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.

BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

INTRODUCTION: Lower extremity peripheral artery disease (PAD) is increasing in prevalence in low- and middle-income countries creating a large health care burden. Clinical management may require substantial resources but little consideration has been given to which treatments are appropriate for les...s advantaged countries.
EVIDENCE ACQUISITION: The aim of this review was to systematically appraise published data on the costs and effectiveness of PAD treatments used commonly in high-income countries, and for an international consensus panel to review that information and propose a hierarchy of treatments relevant to low- and middle-income countries.
EVIDENCE SYNTHESIS: Pharmacotherapy for intermittent claudication was found to be expensive and improve walking distance by a modest amount. Exercise and endovascular therapies were more effective and exercise the most cost-effective. For critical limb ischemia, bypass surgery and endovascular therapy, which are both resource intensive, resulted in similar rates of amputation-free survival. Substantial reductions in cardiovascular events occurred with use of low cost drugs (statins, ACE inhibitors, anti-platelets) and smoking cessation.
CONCLUSIONS: The panel concluded that, in low- and middle-income countries, cardiovascular prevention is a top priority, whereas a lower priority should be given to pharmacotherapy for leg symptoms and revascularisation, except in countries with established vascular units.
