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

Of the 4119 number of confirmed cases, 136 reported travel history. For 87 cases, travel history location was unknown.

The mean delay between confirmation and entry of suspected case was 4.12 days (median 2 days) and varied by country (n = 523 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 203. The country with the highest number of genomic sequences reported is Germany. 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. 98 percent of cases (for which there was an entry for gender) are described as male. The mean age of confirmed cases is 40.

Figure 4: Age and gender distribution of monkeypox confirmed cases in 2022. 18% of confirmed cases include sufficient metadata to be included in this figure. Of these cases, 96% include reported age ranges that span multiple age categories. Under such circumstances, counts are evenly distributed among the categories that capture the reported age range.
