Seasonality
This repository is an initiative to provide analytical tools to analyze Severe Acute Respiratory Infections (SARI) notifications registered at SINAN, the Brazilian Notifiable Diseases Information System (www.saude.gov.br/sinan). Analyzis are performed for each Brazilian State as well as by influenza-like illnessess (ILI) regions.
This is a product of the joint work between researchers at the Scientific Computation Program at Oswaldo Cruz Foundation (Fiocruz, PROCC), School of Applied Mathematics at Fundação Getúlio Vargas (EMAp-FGV), both from Rio de Janeiro, Brazil, and the Inluenza Work Force at the Health Surveillance Secretariat of the Brazilian Ministry of Health (GT-Influenza, SVS, MS).
Threshold definition is based on the Moving Epidemics Method by Jose E.
