As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Background: The impacts of air pollutants on health range from short-term health impairments to hospital admissions
and deaths. Climate change is leading to an increase in air pollution.
In the current absence of vaccine for COVID-19, public health response target breaking the chain of infection by focusing on the mode of transmission. This paper summarizes current evidence-base around the transmission dynamics, pathogenic, and clinical features of COVID-19, to critically identify i...f there are any gaps in the current IPC guidelines.

Since the description of the first case of COVID-19 in Wuhan, Hubei province in China, in December 2019, much knowledge has been accumulated about the dynamics of evolution of the SARS-CoV-2 virus, contagion, disease progression, prevention and treatment.

As the world population is growing and health care resources are in high demand the pressure on medical services is becoming higher. Developing countries are already at a crisis point in health care provision, and time demands a new approach in structuring medical resources. Primary care is t...he vital pillar for fundamental health care at community level and has been deemed as a cost-effective modality. In the West the primary care physician manages chronic medical conditions in communities and therefore reduces unnecessary hospital admissions. In the West, the primary care system is extremely well organised. Low-income countries must improve teaching, training and funding in primary care. In this article the urgent need for primary care is discussed in developing countries, and ways to minimise costs and improve clinical outcomes at community level.

Using the WHO model list of essential medicines to update a national essential medicines list
Since 1977, WHO has been working with countries to design the package of essential medicines as an integral component of treatment within the continuum of care, developing and disseminating the Model List ...of Essential Medicines (Model List). WHO is committed to supporting Member States in sharing best practices in selecting
essential medicines, and in developing processes for the selection of medicines for national essential medicines lists (national EMLs, or NEMLs) consistent with the evidence-based methods used for updating the WHO Model List.

INTRODUCTION: The COVID-19 pandemic has disrupted health systems around the world. The objectives of this study are to estimate the overall effect of the pandemic on essential health service use and outcomes in Mexico, describe observed and predicted trends in services over 24 months, and to estimat...e the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

Over the ages, human societies have altered local ecosystems and modified regional climates. Today the human influence has attained a global scale. This reflects the recent rapid increase in population size, energy consumption, intensity of land use, international trade and travel, and other human a...ctivities. These global changes have heightened awareness that the long-term good health of populations depends on the continued stability of biosphere's ecological, physical and socioeconomic systems.
The world's climate system is an integral part of the complex of life-supporting processes. Like other large systems, the global climate system is coming under pressure from human activities.
This book seeks to describe the context and process of global climate change, its actual or likely impacts on health, and how human societies and their governments should respond with particular focus on the health sector.

In the Indian state of Bihar, visceral leishmaniasis (VL) is a major public health issue that has been aggravated by the rising incidence of new Human immunodeficiency virus (HIV) infections. In endemic areas, the risk of VL infections in patients living with HIV (PLHIV) is higher. It is important t...o investigate the disease-related knowledge, attitude, and practices (KAP) of PLHIV in Bihar in order to monitor HIV/VL co-infection. Adequate knowledge, a positive attitude, and good practices for VL control are essential to stamp out the disease. This study investigated the KAP towards VL in HIV patients attending antiretroviral therapy (ART) clinic at ICMR-RMRIMS, Patna.

Modelling the health impacts of disruptions to essential health services during COVID-19 Module 1
Several epidemiological models have been created to assess the potential impact of disruptions to essential health services caused by COVID-19 on morbidity and mortality from conditions other than COVI...D-19 illness. This guide presents models that have been used to assess these indirect impacts. The effects have been studied in various settings, using a variety of models.
The guide is intended for people who need to understand what the models say, their construction and their underlying assumptions, or need to use models and their outcomes for planning and programme development and to support policy decisions for a country or region.
