COVID-19: new virus variantsA number of new COVID-19 virus variants have been identified across the world
- This updates the news item of 15 January 2021
A number of new variants of the SARS-CoV-2 virus, which causes coronavirus disease (COVID-19), have been identified, originating from different countries across the world [1,2].
Surveillance globally continues to identify changes in the virus; this is to be expected and most new variants are not generally a cause for concern .
However, it is the variants that increase transmission from person to person or can evade the host immune response that are considered variants of concern, resulting in increased cases and pressure on health care systems globally [4, 5].
Advice for travellers
If a new variant of concern is identified, you may experience disruption to your journey or plans at short notice such as:
- Immediate travel restrictions, including flight cancellations and suspension of entry into the UK. Check with your airline or travel provider before setting out on your journey and also prior to your return to the UK. A list of countries with travel restrictions in place can be found on GOV.UK.
- Additional public health measures: i.e. those sharing a household with anyone who is self-isolating, after returning from a country where travel is suspended, may also be required to self-isolate.
- Not being eligible for the Test to Release scheme on your return.
- Closure of land borders to limit the spread of variants to neighbouring countries.
Travellers are recommended to check their travel insurance policy and to be prepared if time abroad is unexpectedly extended due to the implementation of new restrictions.
