Policy brief, 24 July 2020
The COVID-19 pandemic has affected older people disproportionately, especially those living in long-term care facilities. In many countries, evidence shows that more than 40% of COVID-19 related deaths have been linked to long-term care facilities, with figures being as h

igh as 80% in some high-income countries. Concerted action is needed to mitigate the impact across all aspects of long-term care, including home- and community-based care, given that most users and providers of care are those who are vulnerable to severe COVID-19.
This policy brief provides 11 policy objectives and key action points to prevent and manage COVID-19 across long-term care. Its intended audience is policy makers and authorities (national, subnational and local) involved in the COVID-19 pandemic. The brief builds on currently available evidence on the measures taken to prevent, prepare for and respond to the COVID‑19 pandemic across long-term care services including care providers

The Zambia Population Based HIV impact assessment of 2016, reported the prevalence of viral hepatitis in Zambia as ranging between 5.6% among adults aged 15 to 59% in the general population, and 7.1% among HIV infected individuals. It is estimated that the majority of persons with chronic hepatitis

B and/ or hepatitis C are unware of their infection and do not benefit from promotive, preventive and curative services designed to reduce onward transmission. Zambia introduced hepatitis B virus vaccine to the routine Under 5 vaccination schedule in 2005. Preliminary results from the ZAMPHIA indicate that hundreds of infections have been abated in children since then. However, its also clear that we continue to miss key opportunities to prevent transmission, diagnose and treat infections, prevent serious disease, and in many cases cure people. In addition, high risk groups inter alia health care workers still have limited access to the vaccine.

Every year, an estimated 15 million babies are born preterm – before 37 weeks of pregnancy. That is more than 1 in 10 live births. Approximately 1 million children die each year worldwide due to complications from their early birth. Those that survive often face a lifetime of ill-health including

disability, learning difficulties, and visual and hearing problems.
Half of the babies born at or below 32 weeks (2 months early) die in low-income settings, due to a lack of feasible, cost-effective care, such as warmth, breastfeeding support, and basic care for infections and breathing difficulties. In high-income countries, almost all these babies survive.

partners, and experts on use case scenarios and associated testing algorithms for COVID-19 antigen tests. It recommends the use of antigen tests to increase access to testing and enable timely results for persons with or without symptoms in specific settings. The document will be reviewed and updated as more evidence becomes available regarding the use of rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from global studies and evaluation efforts.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition

al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

tions in 2010. Globalization, trade, travel, demographic trends, and warming temperatures are associated with the recent spread of the primary vectors Aedes aegypti and Aedes albopictus and of dengue. Overall, models project that new geographic areas along the fringe of current geographic ranges for Aedes will become environmentally suitable for the mosquito’s lifecycle, and for dengue transmission. Many endemic countries where dengue is likely to spread further have underdeveloped health systems, increasing the substantial challenges of disease prevention and control. Control focuses on management of Aedes, although these efforts have typically had limited effectiveness in preventing outbreaks. New prevention and control efforts are needed to counter the potential consequences of climate change on the geographic range and incidence of dengue, including novel methods of vector control and dengue vaccines.

act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim

ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are
...
limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire
...
ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.
