Comparative Serological Study for the Prevalence of Anti-MERS Coronavirus Antibodies in High- and Low-Risk Groups in Qatar.

In conclusion, we report a low prevalence of anti-MERS antibodies in the general population, which coincides with the low number of all reported cases by the time of our study (2017) in Qatar (n = 21). The false-positive results and the observed cross-reactivity between MERS-CoV and other circulating human coronavirus necessitate more detailed evaluation of available serological assays.

The alignment-free methods are popular nowadays, whereas the manual intervention in those methods usually decreases the accuracy. Also, the interactions among nucleotid...

Abstract The International Society for Influenza and other Respiratory Virus Diseases held its 6th Antiviral Group (isirv-AVG) conference in Rockville, Maryland, November 13-15, 2018. The three-day program was focused on therapeutics towards seasonal and pandemic influenza, respiratory syncytial virus, coronaviruses including MERS-CoV and SARS-CoV, human rhinovirus, and other respiratory viruses. Updates were presented on several influenza antivirals including baloxavir, CC-42344, VIS410, immunoglobulin, immune plasma, MHAA4549A, pimodivir (JNJ-63623872), umifenovir, and HA minibinders; RSV antivirals including pr...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

Authors: Mandil A, Bresee J, Tageldin MA, Azad TM, Khan W Abstract Infectious diseases continue to represent a significant threat to global health security, particularly in the context of increasing globalization, interconnectedness and interdependence. Chief among such threats are influenza viruses and other respiratory pathogens, such as Middle East Respiratory Syndrome coronavirus (MERS-CoV), because of their risk of high transmissibility and acuity of illness. Annual epidemics of seasonal influenza cause an estimated 3-5 million cases of severe illness and more than 500 000 deaths, with the prospect of pandemic...

Abstract Infectious diseases caused by enveloped viruses, such as influenza, SARS, and MERS, cause thousands of deaths and billions of dollars of economic losses per year. Studies have found a relationship among temperature, humidity, and influenza virus incidence, transmission, or survival; however, there are contradictory claims about whether absolute humidity (AH) or relative humidity (RH) is most important in mediating virus infectivity. Using the enveloped bacteriophage Phi6, which has been suggested as a surrogate for influenza virus and coronaviruses, we designed a study to discern whether AH, RH, or T is a...

Extracorporeal life support (ECLS) has been widely utilized to treat neonatal respiratory failure for two decades. However, its uptake in the case of adult respiratory failure has been slow because of a paucity of quality evidence and a sluggish tempo of ECLS-related technological advances. In recent years, interest in ECLS has been piqued after encouraging results were reported from its use during the 2009 H1N1 influenza pandemic. In a world constantly under threat from another influenza epidemic or deadly novel respiratory infection, e.g., the severe acute respiratory syndrome (SARS) virus, the Middle East respiratory sy...

In this study, we used this effect as a criterion to identify and characterize the bona fide SARS-CoV FP. Our results indicate that both FP1 and the region immediately downstream (amino acids 816–835 KQYGECLGDINARDLICAQKF, FP2) induce significant membrane ordering. Furthermore, their effects are calcium-dependent, which is consistent with in vivo data showing that calcium is required for SARS-CoV S-mediated fusion. Isothermal titration calorimetry showed a direct interaction between calcium cations and both FPs. This Ca2+-dependency membrane ordering was not observed with influenza FP, indicating that the coronavirus...

Infectious diseases are considered emerging when the number of persons who are contracting them increases over the previous 20 years or when such an increase is threatened. Those that are readily transferred from person to person have the potential to spread rapidly throughout the world. Among the recent emerging infections are severe acute respiratory syndrome (SARS), MERS CoV, Ebola, and, most recently, Zika virus. These are largely coronaviruses or influenza viruses and are spread via droplets, aerosols, or direct contact with respiratory secretions of someone with the infection.
