Weekly Epidemiological Record (WER)

The Weekly Epidemiological Record (WER) serves as an essential instrument for the rapid and accurate dissemination of epidemiological information on cases and outbreaks of diseases under the International Health Regulations and on other communicable diseases of public health importance, including emerging or re-emerging infections.

An electronic bilingual English/French version of the WER is accessible every Friday and can be downloaded free of charge.

An e-mail subscription service exists, which provides by electronic mail the table of contents of the WER.

WHO has recently started the migration of all its Web pages towards a new content management system in order to navigate in a smoother and more efficient manner.

The task is however complex, and we are expecting a few more weeks before the full migration of both the website and the archives of the Weekly Epidemiological Record (WER) is completed.

We apologize for the inconvenience and the disruption you may encounter. In the meantime, should you need to access specific issues of past WERs please contact us by email (werreh@who.int) and we will be happy to share the relevant PDF files.

Many thanks in advance for your understanding and patience.
