Although there are currently no data showing that COVID-19 affects pregnant people differently than others, we do know that pregnant people are at greater risk of getting sick from other respiratory viruses than people who are not pregnant. Sometime...s, this causes adverse outcomes for the mother or child. Therefore, if you are pregnant, be mindful about reducing your risk of getting sick.

The decontamination of instruments and medical devices plays a very important role in the prevention of health care-associated infections (HAIs). Indeed, improper decontamination of surgical instruments, endoscopic devices, respiratory care devices ...and reusable haemodialysis devices still occurs in many settings, leading to HAIs. This course is based on the WHO manual on decontamination and reprocessing of medical devices for health care facilities, as well as in collaboration with the US CDC.

Over the past weeks, there has been wide media attention on the risk of transmission of the novel coronavirus [severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)] by asymptomatic individuals. This situation has also been extensively discus...sed on various platforms globally. The purpose of this position statement is for the Africa Centres for Diseases Control and Prevention (Africa CDC) to clarify the situation of transmission of SARS-CoV-2 by pre-asymptomatic and asymptomatic Individuals.

N95 or equivalent respirators are single-use personal protective equipment (PPE) designed for use by health workers that provide direct care to patients with diseases transmitted by aerosols or during aerosol generating procedures (AGP) for patients... with acute respiratory disease, as is the case of COVID-19. • Given the current shortage of N95 and equivalent respirators, the World Health Organization (WHO) has suggested the possibility of their extended use by the same individual for up to 6 hours or the reprocessing of respirators when necessary.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensiv...e method to test for SARS-CoV-2 than the reference method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

The checklist is aligned with, and builds upon, existing COVID-19-related WHO guidelines and is structured around protective measures related to: 1) hand hygiene and respiratory etiquette; 2) physical distancing; 3) use of masks in schools; 4) envir...onmental cleaning and ventilation; and 5) respecting procedures for isolation of all people with symptoms. The checklist is designed to support policy-makers, staff and officials from the education and health sectors, local authorities, school principals/leaders and administrators, teachers’ unions, community leaders, school staff, teachers, parents and caregivers.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular disease, diabetes and chronic respiratory diseases and their risk factors are an increasing public health and development challenge in Kazakhstan. This report provides evidence through t...hree analyses that NCDs reduce economic output and discusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

This is a document to support the use of pulse oximeter for assessment of suspected and confirmed cases of Covid-19 in the community.
It is a well-known fact that Covid-19 can present as “happy hypoxia” with minimum symptoms of severe res...piratory distress despite significant low oxygen levels in the blood. The use of pulse oximeter for clinical assessment significantly augments decision making, save lives and provide high quality care. It allows for early detection of patients with hypoxia requiring either close monitoring in the community or timely referral for hospital care.

No country can claim to be free from health-care associated infections, therefore, improvement of infection prevention and control (IPC) strategies is essential. WHO recommends the use of multimodal improvement strategies to implement IPC interventions. These include each item of standard and transm...ission-based precautions according to national guidelines or standard operating procedures and under the coordination of the national IPC focal point (or team, if existing). This publication consists of three focused improvement tools, called “aide-memoires”, which focus on 1) respiratory and hand hygiene, 2) personal protective equipment, and 3) environmental cleaning, waste and linen management, all elements of standard, droplet/contact and airborne precautions.

EID Journal , Volume 27, no.12 , Dec. 2021. Early Release
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections may be underestimated because of limited access to testing. We measured SARS-CoV-2 seroprevalence in South Africa ever...y 2 months during July 2020–March 2021 in randomly selected household cohorts in 2 communities. We compared seroprevalence to reported laboratory-confirmed infections, hospitalizations, and deaths to calculate infection–case, infection–hospitalization, and infection–fatality ratios in 2 waves of infection. Post–second wave seroprevalence ranged from 18% in the rural community children <5 years of age, to 59% in urban community adults 35–59 years of age. The second wave saw a shift in age distribution of case-patients in the urban community (from persons 35–59 years of age to persons at the extremes of age), higher attack rates in the rural community, and a higher infection–fatality ratio in the urban community. Approximately 95% of SARS-CoV-2 infections were not reported to national surveillance.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and ana...lyzed in the laboratory of Instituto Nacional de Investigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.
