Testing and diagnosis of hepatitis B (HBV) and C (HCV) infection is the gateway for access to both prevention and treatment services, and is a crucial component of an effective response to the hepatitis epidemic. Early identification of persons with chronic HBV or HCV infection enables them to recei...ve the necessary care and treatment to prevent or delay progression of liver disease. Testing also provides an opportunity to link people to interventions to reduce transmission, through counselling on risk behaviours and provision of prevention commodities (such as sterile needles and syringes) and hepatitis B vaccination.

While the full extent of Cyclone Ida’s impact is still being assessed, early reports indicate significant damage to infrastructure and livelihoods, with an estimated 3,000km2 of land submerged. Preliminary government reports as of 24 March indicate that more than 58,600 houses have been damaged, i...ncluding 36,747 totally destroyed, 19,733 partially destroyed and 2,184 flooded. More than 500,000 hectares of crops have been damaged, which is expected to significantly increase food insecurity given that the flooding has coincided with the annual harvest season. More than 3,100 schools have been damaged, along with at least 45 health centres.
Nearly 110,000 people remained displaced in more than 130 accommodation centres – mostly schools and other public buildings – in Sofala (90), Manica (26), Zambezia (10) and Tete (4), where humanitarian needs are acute and both the risk of communicable disease outbreaks and protection risks – particularly for women and girls – are high

Antimicrobial resistance represents a big threat to public health. The Centers for Disease Control and Prevention (CDC) estimate that every year two million Americans are infected with a (multi-)drug resistant bacterium, resulting in 23,000 deaths. The WHO has repeatedly drawn attention to this majo...r health issue. In the worst-case scenario, we will shortly run out of effective antibiotics. Surgery and cancer therapy will then become very dangerous due to the risk of infection associated with such treatments. (Organ) transplantation will become close to impossible as the immunosuppression necessary for transplant patients makes them highly vulnerable to infections. Some infections we can easily treat today could turn deadly. It is therefore conceivable that infectious diseases once again become the leading cause of death as in early 20th century.

As the number of transboundary pest and animal and foodborne disease outbreaks rises, so does the number of people who are chronically hungry due to these and other factors. The correlation can be explained by the link between our health and that of the planet. We rely on land and sea for the produc...tion of safe and quality foods for our daily nourishment. Pests and disease epidemics negatively impact the quality, quantity and safety of our food sources, and cripple economic growth and efficiencies in production. Furthermore, the epidemic and endemic levels of the pathogens and disease vectors can be difficult to control. This is why FAO stresses and promotes the special efforts required for cost-effective preventive measures rather than the more expensive control, disinfestation, treatment and disposal measures. When preventive measures are late or difficult, preparedness and contingency plans must be in place to enable rapid response. Early warning systems, based on close monitoring, surveillance, and timely reporting are fundamental to warn and empower communities to safeguard their livelihoods and assets by enhancing disease and pest prevention measures and for government services to take immediate measures to protect communities and national economies.

A new respiratory infectious disease, COVID-19, caused by a new coronavirus called SARS-CoV-2, emerged in early December 2019. Since then, the virus has spread to India and 106 other countries in Asia, Europe, North America, Africa, and Oceania. On March 11, the World Health Organization (WHO) decl...ared the outbreak a pandemic, which has since rapidly evolved. As an economic hub with substantial global connectivity and movement of people and goods, India is directly impacted by the COVID-19 pandemic. Although it is too early to gauge the full spectrum of the outbreak’s social and economic impacts, COVID-19 has already caused lockdowns in China, Korea, and in many countries in Europe, and in some states of India, suspension of schools and universities, disruption of food systems and other supply chains, as well as a slowdown in trade between India and rest of the world.

For COVID-19, as for many infectious diseases, the true level of transmission is frequently underestimated because a substantial proportion of people with the infection are undetected either because they are asymptomatic or have only mild symptoms and thus typically fail to present at healthcare fac...ilities. There may also be neglected or under-served segments of the population who are less likely to access healthcare or testing. Under-detection of cases may be exacerbated during an epidemic, when testing capacity may be limited and restricted to people with severe cases and priority risk groups (such as frontline healthcare workers, elderly people and people with comorbidities). Cases may also be misdiagnosed and attributed to other diseases with similar clinical presentation, such as influenza.
Differences in mortality between groups of people and countries are important proxy indicators of relative risk of death that guide policy decisions regarding scarce medical resource allocation during the ongoing COVID-19 pandemic. This document is intended to help countries estimate CFR and, if possible, IFR, as appropriately and accurately as possible, while accounting for possible biases in their estimation

Poor sanitary conditions in disaster-stricken areas result in higher risk for diarrheal illness in vulnerable populations, especially children. This disease negatively impacts the nutritional status of affected children and causes significant morbidity and mortality. Early di...agnosis and treatment are thus essential to reduce the impact of diarrheal diseases on people affected by disasters. Early identification of cases allows the implementation of measures needed to prevent or lessen outbreaks that can occur in displaced populations in this context. The use of primary care management tools, such as the Integrated Management of Childhood Illness (IMCI) strategy is highly important.This module will first discuss diarrheal diseases and their management, and dehydration and its treatments.

Antimicrobial resistance (AMR) surveillance plays an important role in the early detection of resistant strains of public health importance and prompt response to outbreaks in hospitals and the community. Surveillance findings are needed to inform medical practice, antibiotic stewardship, and policy... and interventions to combat AMR. Appropriate use of antimicrobials, informed by surveillance, improves patients’ treatment outcomes and reduces the emergence and spread of AMR. This protocol describes the steps and procedures to establish/enhance AMR surveillance in Latin America and the Caribbean.

Countries across the world are facing diverse epidemiological situations with varying response
capacities and access to life saving tools. The World Health Organization (WHO) recommends that national authorities continue to apply a risk-based approach when implementing measures related to COVID-19... and international travel while respecting the dignity, human rights and fundamental freedoms of travellers. This approach should consider the risk posed by travel for the importation and exportation of cases in the context of the evolving epidemiology, including the emergence and circulation of virus variants of concern; the expansion of the COVID-19 vaccination roll-out; and lessons learned while responding to the pandemic, including on the early detection and management of cases and the application of public health and social measures.

The purpose of cancer screening tests is to detect pre-cancer or early-stage cancer in asymptomatic individuals so that timely diagnosis and early treatment can be offered, where this treatment can lead to better outcomes for some people.
The aim of a cancer screening programme is either to reduc...e mortality and morbidity in a population by early detection and early treatment of a cancer (for example, breast screening) or to reduce the incidence of a cancer by identifying and treating its precursors (such as cervical and colorectal screening).
This short guide is designed to be a quick reference that contains the important ideas about cancer screening. Readers should refer to other publications for comprehensive discussion and detailed guidance on cancer screening programmes.

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o...r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

Glaucoma is a leading cause of irreversible blindness globally. In Malawi, glaucoma accounts for 15.8% of the blindness among people aged 50 years and above. Blindness from glaucoma is preventable with early detection and timely treatment. However, glaucoma management remains a challenge to eye care... providers due to its asymptomatic progression.
These guidelines inform eye care providers about the requirements for early detection of glaucoma, and the appropriate assessment and management of glaucoma patients. The guidelines also demonstrate the need for ophthalmologists to work with secondary-level eye care providers. With
glaucoma being a permanently blinding condition, it is vital to ensure that all eye care providers are adequately equipped with skills and resources for the early detection and management of glaucoma.
