Abstract
Since the beginning of 2020, health authorities have been monitoring the cases of Coronavirus Disease 2019 (COVID-19), which has grown every day in Brazil and around the world, becoming pandemic. The new coronavirus, also called SARS-CoV-2 by scientists spreads rapidly, causing fear, deaths, and threats for the economy of several countries. This work aimed to describe the clinical characterization of the first cases of a new Brazilian variant of SARS-CoV-2 (P1) in the State of Alagoas, which occurred on February 16th, 2021. Two cases are described: first, a person infected in Amazonas State, where the new variant P1 was first described, who migrated to Alagoas State, and second, a case of probable community transmission within Alagoas, since the patient had no history of recent travel. In both confirmed cases the symptoms were mild. Further studies are necessary to better understand the clinical behavior of P1 SARS-CoV-2 variant and also the associated sequelae in the context of COVID-19.

Abstract
SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus 2) has accumulated multiple mutations during its global circulation. Recently, three SARS-CoV-2 lineages, B.1.1.7 (501Y.V1), B.1.351 (501Y.V2) and B.1.1.28.1 (P.1), have emerged in the United Kingdom, South Africa and Brazil, respectively. Here, we have presented global viewpoint on implications of emerging SARS-CoV-2 variants based on structural-function impact of crucial mutations occurring in its spike (S), ORF8 and nucleocapsid (N) proteins. While the N501Y mutation was observed in all three lineages, the 501Y.V1 and P.1 accumulated a different set of mutations in the S protein. The missense mutational effects were predicted through a COVID-19 dedicated resource followed by atomistic molecular dynamics simulations. Current findings indicate that some mutations in the S protein might lead to higher affinity with host receptors and resistance against antibodies, but not all are due to different antibody binding (epitope) regions. Mutations may, however, result in diagnostic tests failures and possible interference with binding of newly identified anti-viral candidates against SARS-CoV-2, likely necessitating roll out of recurring "flu-like shots" annually for tackling COVID-19. The functional relevance of these mutations has been described in terms of modulation of host tropism, antibody resistance, diagnostic sensitivity and therapeutic candidates. Besides global economic losses, post-vaccine reinfections with emerging variants can have significant clinical, therapeutic and public health impacts.
