This interim guidance on oxygen sources and distribution strategies for COVID-19 treatment has been adapted from WHO and UNICEF’s technical specifications and guidance for oxygen therapy devices, which is part of the
...
WHO medical device technical series. This guidance is intended for health facility administrators, clinical decision-makers, procurement officers, planning officers, biomedical engineers, infrastructure engineers and policy-makers. It describes how to quantify oxygen demand, identify oxygen sources that are available, and select appropriate surge sources to best respond to COVID-19 patients’ needs, especially in low-and-middle income countries.

The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public

health, laboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

y support the critically ill and protect the safety of health-care workers. The objective of this algorithm is to give overall guidance for the triage and referral of symptomatic COVID-19 patients. Intended for use by ministries of health, hospital administrators and health workers involved in response planning for COVID-19 and/or patient triage, management and referral, this algorithm provides a general framework to be adapted to local health systems in countries.

In response to the COVID-19 outbreak, this guidance provides information on infection and prevention control (IPC) for older people, their friends and families, carers, and healthcare providers. Anyone who manages, works, volunteers or provides care

at any type of facilities where older people receive care at (long-term care facilities, non-acute care facilities, and home care services), should practice strict IPC to prevent and control COVID-19 outbreaks. It has been observed in different countries that older people have higher case-fatality rate compared to other age groups. Therefore, it is especially important to implement and follow IPC measures at facilities, homes, and other venues that older people frequent.

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.
