The Monkeypox 2022 outbreak has to date been detected in 72 countries (either confirmed or suspected cases), with 62 confirming transmission, 7 countries continuing to have suspected cases only, and 30 countries having discarded cases that were suspected, out of which 14 have only discarded cases. Overall there are 10269 confirmed and 36 suspected cases (as of 2022-07-13; Figure 1A).

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

Of the 10269 number of confirmed cases, 150 reported travel history. For 87 cases, travel history location was unknown.

The mean delay between confirmation and entry of suspected case was 3.5 days (median 2 days) and varied by country (n = 780 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 365, where we consider a genomic sequence to be related to the current outbreak if it was reported from May 2022 onwards. 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. 99 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. 10% 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.
