Coronavirus disease 2019 is also known as COVID-19. It is a viral illness that infects the lungs. It is caused by a virus called SARS-associated coronavirus (SARS-CoV-2). This illness was first seen in late 2019 in China and has spread across the world.
The signs of COVID-19 are like the flu, and y...ou may have a cough, fever, and it may be hard to breathe. It spreads easily through droplets with the virus when you sneeze or cough. The germs also survive on surfaces like tables, door handles, and telephones. That means you can become sick if you touch a surface with the virus and then touch your face.
Some people have a mild case of COVID-19 and are able to stay at home until they feel better. Others may need to be in the hospital if they are very sick. People with COVID-19 most often have to isolate themselves for about 2 weeks.

Diseases that spread easily have always been around. Sometimes these diseases spread from one person to another person. Sometimes they spread from animals to people. Other times, they spread through germs in the water, soil, food, or air.
Some diseases can be prevented or controlled with a vaccinat...ion, like measles. Other diseases may not have a vaccine or drugs to treat them. Because of this, it is important to prevent the spread of diseases.

2nd edition. Children with TB comprise about 10-12% of the total TB cases diagnosed in the country. This burden is likely to be higher given the challenges in diagnosing TB in children. The symptoms of TB in children mimic those of other childhood diseases. Children do not readily expectorate and th...ey have pauci-bacillary TB hence some will be missed using bacteriological tests. The government has however introduced GeneXpert molecular testing that is more sensitive than microscopy in detecting TB. Health care workers therefore need a reference guide to obtaining sputum from children for testing. Treatment of TB in children has been reviewed and now includes Ethambutol. There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition. Nutrition care and support forms an integral part of treatment for a child with TB disease.

Serum Institute of India Pvt. Ltd. [COVISHIELD™, ChAdOx1 nCoV-19 Corona Virus Vaccine (Recombinant)]
The ChAdOx1-S/nCoV-19 [recombinant] vaccine is a replication-deficient adenoviral vecto...r vaccine against coronavirus disease 2019 (COVID-19). The vaccine expresses the SARS-CoV-2 spike protein gene, which instructs the host cells to produce the protein of the S-antigen unique to SARS-CoV-2, allowing the body to generate an immune response and to retain that information in memory immune cells. Efficacy shown in clinical trials in participants who received the full series of vaccine (2 doses) irrespective of interval between the doses was 63.1%, based on a median follow-up of 80 days, but tended to be higher when this interval was longer. The data reviewed at this time support the conclusion that the known and potential benefits of ChAdOx1-S/nCoV-19 [recombinant] vaccine outweigh the known and potential risks.

In order to meet changing global population needs and consumer expectations, healthcare systems worldwide are under transformation and face restructuring. As systems adapt and shift their emphasis in response to the disparate requests for healthcare services, oppor-tunities emerge for nurses, especi...ally the APN, to meet these demands and unmet needs (Bryant-Lukosius et al. 2017; Carryer et al. 2018; Cassiani & Zug 2014; Cooper & Docherty 2018; Hill et al. 2017; Maier et al.2017). In 2002, the International Council of Nurses (ICN) pro-vided an official position on Advanced Practice Nursing (ICN 2008a). Since that time, worldwide development has increased significantly and simultaneously this field of nursing has matured. ICN felt that a review of its position was needed to assess the relevance of the definition and characteristics offered in 2002. This guid-ance paper defines diverse elements such as assump-tions and core components of the APN. The attributes and descriptors presented in this paper are intended to promote a common vision to continue to enable a greater understanding by the international nursing and healthcare communities for the development of roles commonly identified as Clinical Nurse Specialist (CNS) and Nurse Practitioner (NP).

The COVID-19 pandemic arrived in an evolving epidemiological context where some countries are experiencing a progressive decrease in HIV positivity in their testing programme as they are moving closer to the first 95 target. Distinguishing changes in HIV testing services due to the COVID-19 pandemic... from those resulting from evolving HIV testing strategies is crucial for adapting services and helping countries define their strategic mix of testing options moving forward. There is a need to focus, prioritize and plan for strategic efforts to prevent going further off the track toward achieving global targets and goals.
To support these efforts, WHO in partnership with ministries of health conducted an in-depth analysis of HIV testing services and antiretroviral therapy (ART) initiation prior to and during reported COVID-19 disruptions. Additional publicly available Global Fund and PEPFAR data was also reviewed and analysed. This analysis, and coordination with ministries of health, identified key service delivery adaptations utilized during COVID-19-related disruptions and formed the basis of this strategic guide.
This document focuses on current country needs, as well as plans for prioritization and potential surge support needs in the event of future disruptions. Although the data and implications are specific to sub-Saharan Africa, key principles and lessons can be applied elsewhere.

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.

Lancet 2021; 398: Series: Heat and Health
Hot weather and heat extremes harm human health, with poverty, ageing, and chronic illnesses as aggravating factors. As the global community contends with even hotter weather in a changing climate, there is a pressing need to better understand the most eff...ective prevention and response measures, particularly in low-resource settings. In this two-paper series, the physiological, social, and environmental factors that contribute to individual heat vulnerability, and the megatrends affecting future heat-related morbidity and mortality at the population level, are comprehensively reviewed. Solutions to address the physiological heat strain that underlies the negative health effects of heat extremes and hot weather, which can be employed across a range of settings at individual, building, and landscape scales, are presented.

Extreme heat events (EHEs) are a leading cause of weather-related injury and death in the United States, and under a changing climate, these meteorological episodes are predicted to increase in both frequency and intensity. Prolonged heat exposure from EHEs places an increased strain on the heart an...d may lead to heat-related illness if the cardiovascular system fails to properly thermoregulate internal body temperature. Every individual is susceptible to heat-related illness, however, those with reduced cardiovascular function and pre-existing cardiovascular diseases are at a greater risk for morbidity and mortality during EHEs. This document gives an overview of our current understanding of heat exposure and its impact on cardiovascular health outcomes, an overview of the medications that may exacerbate heat-related cardiovascular illness, and asummary of the interaction between extreme heat and air pollutants, and their collective impact on cardiovascular health. Additionally, this document summarizes epidemiologic evidence and identifies gaps in the extant peer-reviewed literature on the effectiveness of strategies and interventions to protect against heat-related cardiovascular disease and death. This information is intended to aid health departments and other health professionals in understanding and responding to the impacts of heat exposure on cardiovascular health.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.
