First childhood flu helps explain why virus hits some people harder than others

Why are some people better able to fight off the flu than others? Part of the answer, according to a new study, is related to the first flu strain we encounter in childhood.Scientists from UCLA and the University of Arizona have found that people ’s ability to fight off the flu virus is determined not only by the subtypes of flu they have had throughout their lives, but also by the sequence in which they are been infected by the viruses. Their study is published in the open-access journal PLoS Pathogens.The research offers an explanation for why some people fare much worse than others when infected with the same strain of the flu virus, and the findings could help inform strategies for minimizing the effects of the seasonal flu.In addition, UCLA scientists, including Professor James Lloyd-Smith, who also was a senior author of the PLoS Pathogens research, recently completed a study that analyzes travel-related screening for the new novel coronavirus 2019-nCoV. (The research is under review;a preprint is online.)The researchers report that screening travelers is not very effective for the 2019 coronavirus — that it will catch less than half of infected travelers, on average — and that most infected travelers are undetectable, meaning that they have no symptoms yet, and are unaware that they have been exposed. So stopping the spread of the virus is not a matter of just enhancing screening methods at airports and other travel hubs.“This puts the...

Authors: Petretto DR, Masala I, Masala C Abstract School closure and home confinement are two of the measures of lockdown chosen by governments and policymakers all over the world to prevent and limit the spread of the infection of COVID-19. There is still an open debate about the real effect of school closure on the reduction of risk of infection on children and the risk of infection on with other age groups (parents, grandparents and others). There is an agreement on the effect of school closure in reducing and delaying the peak of the outbreak. In this Editorial, starting from the ongoing Italian experience, we ...

Authors: Conti P, Caraffa A, Tetè G, Gallenga CE, Ross R, Kritas SK, Frydas I, Younes A, Di Emidio P, Ronconi G Abstract SARS-CoV-2 virus is an infectious agent commonly found in certain mammalian animal species and today also in humans. SARS-CoV-2, can cause a pandemic infection with severe acute lung injury respiratory distress syndrome in patients with COVID-19, that can lead to patient death across all ages. The pathology associated with pandemic infection is linked to an over-response of immune cells, including virus-activated macrophages and mast cells (MCs). The local inflammatory response in the lung...

Conclusions: The antiviral mouthwashes play a certainly important role in reducing the viral load of the salivary virus. In the present study, this importance could be proved in two different aspects, that is, the use of mouthwash before dental procedures to reduce the risk of transmission of the virus to the dental team and the use of this mouthwash in COVID-19 patients to help improve systemic problems associated with oral microbial flora.

Authors: Jung SW, Kim YJ, Han SB, Lee KY, Kang JH Abstract OBJECTIVES: Since the 2000s, two lineages of the influenza B virus (influenza B/Victoria and influenza B/Yamagata) have been co-circulating. Information on the age distribution of patients infected by each influenza B virus lineage may be helpful for establishing differentiated influenza prevention and control strategies for each age group. METHODS: Age distributions were compared between patients infected by influenza A and B viruses and between those infected by the influenza B virus when B/Victoria and B/Yamagata lineages circulated dominantly. R...
