30th Brazilian Society for Virology 2019 Annual Meeting—Cuiabá, Mato Grosso, Brazil

The 30th meeting of the Brazilian Society for Virology (SBV) was held, for the first time in its 30 years of existence, in Cuiabá, the capital of Mato Grosso State, Central Western Brazil, a tropical region between the three richest biomes in the world: Amazon Florest, Cerrado and Pantanal. In recent years, the field of virology has been built in the State. The aim of this report is to support participants and virologists to receive the most up-to-date information about the meeting, which occurred from 16 to 19 October 2019. National and international speakers gave SBV the opportunity to learn about their experience on their virology fields, sharing recent scientific findings, compiling conferences, round table presentations and work presentations in oral and poster sessions. The meeting held over 300 attendants, who were also involved on oral and poster presentations, showing a great variety of recent unpublished studies on environmental, basic, animal, human, plant and invertebrate virology. In addition, SBV offered the Helio Gelli Pereira award for the best research studies in each field presented during the meeting. The 30th meeting of SBV was very productive and has also encouraged scientific partnership and collaboration among virologists worldwide.


Introduction
Virology is a biological research field characterized by rapid advances of concepts, paradigms and understanding of virus biology, epidemiology, pathogenesis, evolution, therapy and control. Viruses have been demonstrated to be the most diverse microorganisms on earth. Human resources and institutions constantly need to update and amplify their resources to go along with this rapid evolution, promoting direct improvements in Brazilian virology education and research institutions. Concerning this, the organizing committee of the 30th Brazilian Society for Virology Meeting provided a coherent scientific program based on national and international high-level selection of researchers to present their recent findings in their fields.
The 30th Brazilian Society for Virology Meeting shared advanced knowledge on important viruses for public health, such as Hepatitis C, Zika, Chikungunya, West Nile and other arboviruses, HIV, HPV, Influenza, oncolytic viruses and those linked to veterinary and agricultural viral diseases. This vast virology approach was explored in order to expand the One Health concept of a global tendency linking human, animal and plant health. The event also allowed students to share their most recent developments, distributed in oral sessions and poster presentations, integrating the academy and giving renowned scientists and new researchers the opportunity to interact in a multi-thematic virological environment.
Therefore, participants experienced in this meeting a unique opportunity to exchange knowledge, share experiences and amplify discussions and extend collaborations with national and international researchers, professors, professionals, postdocs, post-graduate and graduate virology students, reinforcing pre-existing affinities, especially those linked to virologists from Institutions belonging to Mercosul. It is extremely important to highlight that for the first time the event was held in the state of Mato Grosso, an ancient Brazilian region important as an ecotourism destination related to Pantanal and Amazon, which started to develop as economically noteworthy only in recent years, mostly because of the agriculture field. Virology groups in the State are proportionally few and recent, with low inclusion in graduate courses, research and diagnosis. This scientific area has provided in-depth exploration of the full potential of biodiversity observed in the three biomes located at Mato Grosso State; in such a way, it is expected that these professionals will expand their contributions to the national virology scenario in the near future. The fulfillment of an event of this size in the region allowed local researchers and students of diverse areas within virology to present their skills and form bonds with renowned institutions of other geographic regions so that they can increase and strengthen research in virology fields.

Historical Perspectives
The Brazilian Society for Virology (SBV) is a non-profit, non-governmental organization that has organized annual scientific meetings since 1986. The Society itself was initiated from discussions between the former Brazilian Microbiology Society president Prof.  São Paulo (SP) States. The latest three SBV events were held in Pirenópolis, GO, Belo Horizonte, MG, and Gramado, RS. In Gramado 2018, the event received 626 attendants, represented mostly by post-graduate students (40%).

The scientific Program of the 30th SBV Annual Meeting
The scientific program of the 30th SBV Annual Meeting was based on 38 speakers, 31 Brazilian virology researchers and one from Argentina, four speakers from European institutions-France, Spain and England-and two from USA research groups, distributed over basic, environmental, veterinary, human, plant and invertebrate virology. Speakers represented 8 (21.1%) former SBV members, 22 (57.9%) national and international senior scientists and 8 (21.1%) young researchers distributed in all virology fields that completed their Ph.Ds within less than 10 years, representing the SBV commitment to give an opportunity to recent doctors and research beginners to create solid research lines and interactions with renowned researchers in their fields. All seven conferences and 23 round table speeches were made by men; 14 women presented their research findings in round tables, emphasizing the necessity to improve women's participation on SBV meetings as speakers. On the other hand, 295 posters were presented by 145 (63%) women and 85 (37%) by men; 25 (65.8%) oral presentations were made by women and 13 (34.2%) by men; 6 (50%), although awarded oral presentations (n = 12), were made 50% by women, 50% by men. These statistics show that we must improve and recognize women's participation in the most relevant activities in future meetings since they represent the majority of participants, posters and oral presenters nowadays in Brazilian virology fields.
Speakers were distributed over seven main conferences and 12 round tables, including four presentations of the most recent subjects on the fields of antivirals, plant virus diversity and evolution, virology of plants and invertebrates, virus-cell interactions, emerging viruses, oncolytic immunotherapy, viral structure and pathogenesis, viral global spread, small animal viruses, omics virology and environmental virology.
The 30th SBV Annual Meeting also hosted eight sections of students' oral presentations, two sharing basic, human and veterinary research studies, one of plant and invertebrate and finally, one of environmental virology. All of these eight sections of oral presentations, in addition to poster presentations by virology field, applied for the Helio Gelli Pereira (HGP) award, which this year granted a free publication fee on Viruses Journal for the two general winners and a fee deduction for each field first position in oral and poster presentation.

Scientific Program
For four days, the 2019 SBV occurred in Centro de Eventos do Pantanal, a strategic area located in the capital of Mato Grosso (MT) State, Cuiabá. The event was divided amongst the facilities of this modern and sustainable building with simultaneous conferences and round tables (Table 1).

Conference Speakers and Presentations
Dr. Elliot Watanabe Kitajima is a plant virologist from Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo (USP), Brazil. Over his career, he has contributed to the discovery and characterization of several plant viruses, resulting in more than 400 research articles, 12 books and 31 book chapters. Due to his impressive contributions, a viral family was named in his honor as the Kitaviridae family. His main opening conference was based on plant viruses transmitted by Brevipalpus saga.
Dr Dr. Valerian Dolja, a researcher at Oregon State University from the USA, showed his impressive studies on virus evolution in his presentation "Origin of viruses: primordial replicators recruiting capsids from hosts". His group publications have changed the way that the International Committee on Virus Taxonomy (ICTV) and virologists around the world currently classify viruses.
Dr. Glenn C. Randal from University of Chicago, USA, is a human virologist developing research on Dengue and hepatitis C pathogenesis. In our meeting, Dr. Randal shared his studies on Hepatitis C virus-host interactions. Tables   Round table 1

ASM granted a 1-year membership to ASM and full discount for publication of the awardees, if the manuscript was accepted by referees and editors, respectively. One of the works was recently published in Viruses [16].

Concluding Remarks
The 30 th Brazilian Society for Virology Meeting provided a unique opportunity for scientists, undergraduate and postgraduate students, professionals and principal investigators to share information and exchange experiences in virology with a broad perspective. The meeting explored recent research findings in all the main fields of virology, reinforcing the importance of this knowledge area for modern science. The fact that this meeting was held for the first time in Cuiabá, South-Central Mato Grosso strengthens the virology field in the State through a network of international and national collaboration. Therefore, SBV also invests in recent researchers' consolidation and enhances its purpose, which is to promote the exchange of information and to stimulate discussion and collaboration among virologists bringing the virology field as a key point in science and development. Consolidation of virology in Brazil strongly reinforces rapid and efficient responses to the emergence and re-emergence of public, animal and agriculture health-important viruses.
