Summary

The Monkeypox 2022 outbreak has to date been detected in 57 countries (either confirmed or suspected cases), with 42 confirming transmission, 11 countries continuing to have suspected cases only, and 21 countries having discarded cases that were suspected. Overall there are 2077 confirmed and 100 suspected cases (as of 2022-06-17; Figure 1A). Since 2022-06-16, 271 new confirmed cases have been reported, and 5 new countries have been added to the list (Georgia, Luxembourg, Mexico , Nepal, Slovakia) (Figure 1B).

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

Of the 2077 number of confirmed cases, 109 reported travel history. For 74 cases, travel history location was unknown.

The mean delay between confirmation and entry of suspected case was 3.7 days (median 4 days) and varied by country (n = 333 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.
