In many countries, as restrictions lift and freedoms are restored, there’s a general feeling that the pandemic is over. There is, however, still the significant concern that a dangerous new variant could emerge.
This happened when omicron arrived, but we got lucky with that one. Omicron turned out to be more transmissible, but mercifully it hasn’t caused an increase in severe disease in most countries where it is dominant.
But this wasn’t guaranteed. Variants crop up randomly, and new ones have the potential to be more dangerous than previous ones. Another has just arrived, and is currently going by the name deltacron. It is – as you can probably guess – a hybrid of delta and omicron, the two variants dominant most recently.
