RESUMO
In late 2019, a novel coronavirus, now designated SARS-CoV-2, emerged and was identified as the cause of an outbreak of acute respiratory illness in Wuhan, a city in China, named as COVID-19. Since then the waves of the virus exponentially hit many countries around the globe with high rates of spread associated with variable degrees of morbidity and mortality. The WHO announced the pandemic state of the infection in March 2020 and by June 1st 2020 more than 6 million individuals and more than 370 thousands case fatalities were documented worldwide. In this article, we discussed many aspects regarding this emerged infection based on the available evidence aiming to help clinician to improve not only their knowledge but also their practices toward this infection.

"Tick - host specificity. Results of an intense sampling study in Madagascar"" : Ticks are traditionally considered being host-specific parasites. The pattern of tick-host relationship was elucidated by exhaustive collection from a considerable number of potential hosts from numerous sites in the Malagasy mid-altitude forest. It can from the findings be concluded that the Malagasy ticks found on small mammals may be distinguished as either having a broad host-specificity or being highly host-specific. The results may provide important information in respect to phylogenetic studies with regards to the geological history of Madagascar and its endemic fauna."
