Most patients had elevated levels of ALT (60%), AST (90%), LDH (94%), and ferritin (69%) in serum. The imaging of brain damage on MRI and CT scans varied in patterns and locations. There was no difference in the timing of methylprednisolone treatment within and after 48 h.

A key effort in response was the need for a substantial expansion in laboratory testing and diagnosis to monitor the spread of the virus and to provide critical data to support effective public health measures. The scale of the threat drove research and innovation in laboratory diagnostics and genomic surveillance, enhancing testing capabilities and providing technological support to countries that previously did not have access to the key capabilities for rapid detection of pathogens that are necessary to prevent the next outbreak from becoming a pandemic.&lt;/p&gt;&lt;p&gt;The WHO Eastern Mediterranean Region (EMR) comprises the Occupied Palestinian Territories and 21 member states: Afghanistan, Bahrain, Djibouti, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Qatar, Saudi Arabia, Somalia, Sudan, Syrian Arab Republic, Tunisia, United Arab Emirates, and Yemen. These countries have a diverse range of socio-economic and demographic conditions, and many are facing humanitarian crises caused by civil conflict and natural disasters. Despite these challenges, member states in the region, supported by national, regional, and international stakeholders, were able to mount variable but largely robust laboratory responses, increasing COVID-19 diagnostic and genomics capacity to covering 100% of the region [&lt;span&gt;1&lt;/span&gt;]. This special issue provides an insight into the challenges faced in this rapid scale-up of capacity, as well as the extraordinary efforts taken to overcome them during the pandemic.&lt;/p&gt;&lt;p&gt;The key initiatives highlighted throughout this issue are now being redirected towards a sustainable laboratory network with the capacity to detect and respond to new and re-emerging pathogens that pose threats to public health in the region and globally, with the goal of preventing the next outbreak from becoming a pandemic. The investment in strengthening testing capacity, through molecular platforms such as PCR and genomics, that play a pivotal role in detecting and monitoring COVID-19 and other respiratory viruses, are now being expanded to include detection of priority pathogens with epidemic and pandemic potential such as other respiratory pathogens (e.g., MERS-CoV), arboviruses (e.g., dengue), and hemorrhagic fevers (e.g. CCHF), which periodically threaten the region. These capacities are being strengthened and sustained through the development of and investment in national and regional strategies to support genomic surveillance in the region, with efforts underway to establish steering committees and technical working groups to sustain, standardize and enhance genomic sequencing in the region [&lt;span&gt;2&lt;/span&gt;], as well as the continued expansion of quality assurance networks to ensure that laboratories continue to produce robust, reliable results to su","PeriodicalId":13544,"journal":{"name":"Influenza and Other Respiratory Viruses","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/irv.70030","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142576064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
