The assortment of reporting techniques alongside other issues, such as underreporting and budgetary constraints, makes predicting the spread and lethality of the virus a challenging task. This work attempts to gain a better understanding of how COVID-19 will affect one of the least studied countries, namely Brazil. Currently, several Brazilian states are in a state of lock-down. However, there is political pressure for this type of measures to be lifted. This work considers the impact that such a termination would have on how the virus evolves locally. This was done by extending the SEIR model with an on / off strategy. Given the simplicity of SEIR we also attempted to gain more insight by developing a neural regressor. We chose to employ features that current clinical studies have pinpointed has having a connection to the lethality of COVID-19. We discuss how this data can be processed in order to obtain a robust assessment. The online version contains supplementary material available at 10.1186/s13362-020-00098-w.

The genome size ranged from 3962 (BM87) to 7369 bp (BM85) but maximum genomes were in the range of 5-5.5 kb. The GC% had an average of 42% and ranged between 34.69 (BM95) and 52.35 (BM81). A total of 3036 SSRs and 223 cSSRs were extracted using IMEx with incident frequency from 18 to 56 and 0 to 7, respectively. The most prevalent mono-nucleotide repeat motif was "T" (48.95%) followed by "A" (33.48%). "AT/TA" was the most prevalent dinucleotide motif closely followed by "CT/TC". The distribution was expectedly more in
