Table 1: Number of confirmed cases by country (highest to lowest) and percentage change since last week.

Of the 1623 number of confirmed cases, 103 reported travel history. For 68 cases, travel history location was unknown.

The mean delay between confirmation and entry of suspected case was 4.06 days (median 4 days) and varied by country (n = 282 total number of cases where the dates of suspected and confirmed was known; Figure 2). Most countries do not report suspected cases.

Genomic data is being reported via multiple open source repositories. In order to support ongoing genomic surveillance and improve representativeness of genomic sequences we here plot the relationship between number of genomic sequences vs. number of confirmed cases (Figure 3). The (combined) number of genomic sequences of the current outbreak is 79. The country with the highest number of genomic sequences reported is Portugal. A comparison between the number of genomes and number of confirmed cases is below (Figure 3).

The age and gender ratio is shown in Figure 4. 97 percent of cases (for which there was an entry for gender) are described as male. The mean age of confirmed cases is 39.
