Before revision:  We find that the quantity of information about COVID-19 is indeed overwhelming, but that the majority of links shared cannot be rated for its credibility.

The majority of links that could be rated came from credible sources; however, we found a large increase in the proportion of state-sponsored propaganda among non-credible and less credible URLs, suggesting that COVID-19 may be used as a vector to spread misinformation and disinformation for political purposes.
