Internet searches for measures to address COVID-19 in Brazil: a description of searches in the first 100 days of 2020. / Buscas na internet sobre medidas de enfrentamento à COVID-19 no Brasil: descrição de pesquisas realizadas nos primeiros 100 dias de 2020.

OBJECTIVE: to describe profiles of interest of web search queries related to the Covid-19 epidemic in Brazil. METHODS: this was a quantitative and exploratory study using Google Health Trends. We analyzed daily data of interest, defined as search probability (Pr), in 23 terms in searches performed by users connected in Brazil from January 1 to April 9, 2020. RESULTS: the peak in interest (Pr=0.0651) on the theme of coronavirus occurred on March 21. Interest in use of face masks (Pr=0.0041), social distancing (Pr=0.0043) and hand hygiene with alcohol gel (Pr=0.0037) was greater than interest in respiratory etiquette (Pr=0.0010) and hand hygiene with soap and water (Pr=0.0005). CONCLUSION: the difference in interest in issues related to combating Covid-19 was substantial and can guide new strategies for disseminating health information.

Simulating social distancing measures in household and close contact transmission of SARS-CoV-2.

We sought to evaluate contact rate reduction goals for household and close contacts and to provide preventive recommendations during the coronavirus pandemic. We applied an agent-based model to simulate the transmission dynamics of SARS-CoV-2 within household or close contacts through a social network of 150 nodes. there is no great difference in total infected people within modifications in number of links per node for networks with average number of links per node greater than three. For six nodes, total infected people are 149.85; for five nodes, 148.97; and for four nodes, 141.57. On the other hand, for three nodes, total infected are 82.39, for two nodes, 13.95; and for one node, 2.96. This model indicates a possible pitfall if social distancing measures are not stepwise suspended and close surveillance of cases are not provided, since the relationship between average links per node and number of infected people seems to be s-shaped, and not linear.
