Public health in Brazil: Before COVID-19, and after

SUS was created to guarantee universal health care and among the changes that took place in Brazilian public health there was a reduction in inequalities and a sharp drop in mortality from communicable diseases, maternal and child morbidity and mortality, and this impacted the increase in life expectancy. Based on evidence from several other pathogens to facilitate an approach, among these factors are cited; (i) pathogen-specific factors as binding site, environmental persistence, virulence, and infectious dose; (ii) host factors (duration of infection, location, the burden of infection, and symptoms); (iii) environmental factors that including population density and the availability and use of infection prevention and control measures; (iv) and behavioral factors that include cough hygiene, social customs, and adherence to public health guidance. The current pandemic is clearly an international public health problem, but Brazil today, we can add the political instability as another big factor that contributes to the dissemination of COVID-19 because domestic political factors and a possible economic recession hampers the government's ability to strengthen its health systems response in a timely manner to COVID-19 control.
