La OMS ha elaborado una definición de caso clínico de la afección posterior a la COVID-19 mediante la metodología Delphi que incluye 12 dominios, disponible para su uso en todos los entornos. Esta primera versión fue elaborada por pacientes, investigadores y otras personas, en representación d...e todas las regiones de la OMS, en el entendimiento de que la definición puede cambiar a medida que surjan nuevas pruebas y siga evolucionando nuestra comprensión de las consecuencias de la COVID-19.
La afección posterior a la COVID-19 se produce en personas con antecedentes de infección probable o confirmada por el CoV-2 del SRAS, normalmente a los 3 meses de la aparición de la COVID-19 con síntomas y que duran al menos 2 meses y no pueden explicarse por un diagnóstico alternativo. Los síntomas más comunes son la fatiga, la dificultad respiratoria y la disfunción cognitiva, pero también otros, y generalmente tienen un impacto en el funcionamiento diario. Los síntomas pueden ser de nueva aparición tras la recuperación inicial de un episodio agudo de COVID-19 o persistir desde la enfermedad inicial. Los síntomas también pueden fluctuar o recaer con el tiempo.

Diabetes mellitus is one of the most common noncommunicable diseases worldwide. In the Eastern Mediterranean Region there has been a rapid increase in the incidence of diabetes mellitus and it is now the fourth leading cause of death. The increasing prevalence of diabetes mellitus, the emergence of ...diabetes complications as a cause of early morbidity and mortality, and the enormous and mounting burden on health care systems make diabetes a priority health concern. These guidelines provide up-to-date, reliable and balanced information for the prevention and care of diabetes mellitus in the Region. The information is evidence-based and clearly stated to facilitate the use of the guidelines in daily practice. They are intended to benefit physicians at primary, secondary and tertiary level, general practitioners, internists and family medicine specialists, clinical dieticians and nurses as well as policy-makers at ministries of health. They provide the information necessary for decision-making by health care providers and patients themselves about disease management in the most commonly encountered situations.

The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on the clinical, epidemiological and virological chara...cteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

Prompt, effective antimalarial treatment, and supportive care can substantially reduce the rate of mortality from severe malaria. However, many children in malaria-endemic countries do not have access to health facilities or a qualified health care provider and do not receive the necessary care in a... timely fashion. Without rapid detection of danger signs and access to effective treatment, including pre-referral treatment that can be administered in the community level, many of these children with severe malaria die.
In situations where there is no immediate access to a health care facility, WHO recommends the administration of a standard dose of an effective antimalarial medicine as pre-referral treatment before referral to a facility at which complete treatment can be administered.
Rectal artesunate is the WHO-recommended pre-referral intervention in situations where artesunate injection are not feasible for children under the age of 6 years with suspected severe malaria. The intervention reduces the risk of death or permanent disability by up to 50% provided the child is referred to a health facility at which complete treatment can be administered.
This field guide is aimed at supporting the effective deployment of RAS as pre-referral treatment of suspected severe malaria in line with the WHO malaria guidelines.

Scientific Brief 9 July 2020
This document updates the earlier version published in April 2020. In recent weeks, information on the potential use of chloroquine or hydroxychloroquine for the treatment of people with COVID-19 has been disseminated in academic journals and public media. Although there are now ongoing clinical tri...als testing the efficacy and safety of several medicines for COVID-19, as of the date of this document, there is a lack of quality evidence to demonstrate chloroquine and/or hydroxychloroquine are effective in the treatment of COVID-19. Evidence is recently emerging via small studies with sub-optimal methodologies that are conflicting.
