Dozens of countries have introduced travel bans as governments digest the news that a new variant of SARS-CoV-2 had been identified. But is this an effective approach to manage the spread of Omicron, the name the World Health Organization has assigned to the new variant? Shabir Madhi argues not. All they do is delay the inevitable. Governments should rather impose rigorous exit and entry screening programmes to identify potential cases - and mandate
vaccinations. Travel bans are on Madhi’s list of things that aren’t worth doing. He also spells out 10 steps worth pursuing.
For their part Wolfgang Preiser and his colleagues explain how scientists “hunt” for new coronavirus variants and share what they know already about this one.

Research from Meta and some scientists shows no harm from social media, but other research and whistleblower testimony show otherwise. Seemingly contradictory, both can be right.
