Provides tools for downloading, reading and analyzing the COVID19 National
  Household Sample Survey - PNAD COVID19, a household survey from Brazilian Institute
  of Geography and Statistics - IBGE. The data must be downloaded from the official
  website <https://www.ibge.gov.br/>. Further analysis must be made using package 'survey'.

A feasible framework for mutation analysis and reverse transcription 
  polymerase chain reaction (RT-PCR) assay evaluation of COVID-19, including 
  mutation profile visualization, statistics and mutation ratio of each assay. 
  The mutation ratio is conducive to evaluating the coverage of RT-PCR assays in 
  large-sized samples. Mercatelli, D. and Giorgi, F. M. (2020)

  English: Downloads and analyzes data  of COVID-19 from the  Mexican General 
  Directorate of Epidemiology (DGE), the Network of 
  Severe Acute Respiratory  Infections (IRAG network),and the Global 
  Initiative on Sharing All Influenza Data GISAID.

Publicly available COVID-19 data for Norway cleaned and merged into one dataset, including PCR confirmed cases, tests, hospitalisation and vaccination.

We propose a method to estimate the probability of an 
    undetected case of COVID-19 in a defined setting, when a given number of 
    people have been exposed, with a given pretest probability of having 
    COVID-19 as a result of that exposure. Since we are interested in undetected
    COVID-19, we assume no person has developed symptoms (which would warrant 
    further investigation) and that everyone was tested on a given day, and all 
    tested negative.
