[Q]: Although single cell RNA sequencing studies have begun providing compendia of cell expression profiles, it has proven more difficult to systematically identify and localize all molecular cell types in individual organs to create a full molecular cell atlas. Here we describe droplet-and plate-based single cell RNA sequencing applied to ~75,000 human lung and blood cells, combined with a multi-pronged cell annotation approach, which have allowed us to define the gene expression profiles and anatomical locations of 58 cell populations in the human lung, including 41 of 45 previously known cell types or subtypes and 14 new ones. This comprehensive molecular atlas elucidates the biochemical functions of lung cell types and the cell-selective transcription factors and optimal markers for making and monitoring them; defines the cell targets of circulating hormones and predicts local signaling interactions including sources and targets of chemokines in immune cell trafficking and expression changes on lung homing; and identifies the cell types directly affected by lung disease genes and respiratory viruses. Comparison to mouse identified 17 molecular types that appear to have been gained or lost during lung evolution and others whose expression profiles have been substantially altered, revealing extensive plasticity of cell types and cell-type-specific gene expression during organ evolution including expression switches between cell types. This atlas provides the molecular foundation for investigating how lung cell identities, functions, and interactions are achieved in development and tissue engineering and altered in disease and evolution.

[Q]: Even though coronavirus infection of humans is not normally associated with severe diseases, the identification of the coronavirus responsible for the outbreak of severe acute respiratory syndrome showed that highly pathogenic coronaviruses can enter the human population. Shortly thereafter, in Holland in 2004, another novel human coronavirus (HCoV-NL63) was isolated from a seven-month old infant suffering from respiratory symptoms. This virus has subsequently been identified in various countries, indicating a worldwide distribution. HCoV-NL63 has been shown to infect mainly children and the immunocommpromised, who presented with either mild upper respiratory symptoms (cough, fever and rhinorrhoea) or more serious lower respiratory tract involvement such as bronchiolitis and croup, which was observed mainly in younger children. In fact, HCoV-NL63 is the aetiological agent for up to 10% of all respiratory diseases. This review summarizes recent findings of human coronavirus HCoV-NL63 infections, including isolation and identification, phylogeny and taxonomy, genome structure and transcriptional regulation, transmission and pathogenesis, and detection and diagnosis.

The term 'emerging infectious diseases' (EIDs) is a broad one that covers newly recognized human diseases caused by pathogens that have recently jumped species, older pathogens that have emerged in new populations due to human behaviors or modifications to natural habitats, and older pathogens that are exhibiting resurgence in areas once brought under control, usually due to microbiological adaptation and change; this includes previously-identified microorganisms exhibiting new patterns of antimicrobial drug resistance and pathogenic properties. Emerging infectious diseases are those with increasing incidence at local, regional, or international scales, and are spreading from epicenters to new geographic areas. The surveillance, study and control of EIDs is a complex interdisciplinary effort, crossing international borders and involving the collaborative efforts of scientists, clinicians, and political leaders from many disciplines and backgrounds to protect human health. According to a comprehensive literature review performed by Taylor et al. (2001) at the Centre for Tropical Veterinary Medicine at the University of Edinburgh, 1415 species of infectious organisms known to be pathogenic to humans were identified. The human pathogens tabulated by this study included an assortment of 217 viruses and prions, 538 bacteria and rickettsia, 307 fungi, 66 protozoa and 287 helminths. The majority of these (61%) were zoonotic infections transmitted from animals to humans. Of the 175 pathogenic species associated with diseases considered to be 'emerging', 135 (75%) were zoonotic. The study found that protozoan and virus pathogens were particularly likely to emerge, and that the helminths were less likely to do so. Interestingly, no association was found between route of transmission and emergence in this study. An updated literature survey from the Centre for Infectious Diseases at the same institution (University of Edinburgh) was published in 2005 by Woolhouse and Gowtage-Sequeria. This study identified 1407 species of human pathogens, 58% of which were zoonotic. Of the total, 177 were regarded as 'emerging' or 're-emerging' pathogens. The emerging and re-emerging zoonotic pathogens were most likely to have the broadest host ranges. The authors noted that although zoonotic pathogens constitute a significant source for emerging and re-EIDs, only a small minority of them would prove capable of causing major epidemics in the human population -but the H5N1 influenza strain could prove to be an exception. Causal factors contributing to the emergence of new pathogens include human population growth resulting in human encroachment on wildlife habitats, increased human contact with domestic and wild animals, changes in agricultural practices CHAPTER 3 sECTion 1 a PRE-TRAvEl AdviCE
