The Ebola virus caused travel to be restricted in Europe. The move has sparked concerns that the new, mutated strain of the fatal disease could cause even more problems.
The “south african countries” are shutting down travel from the continent. The European Union is also considering a ban on flights from the region.
Europe has halted travel from Southern Africa due to fears of a new virus mutation that is immune to current vaccines.

While the winter will be difficult for Covid – growing cases, including breakthrough cases, and an under-boosted population – I believe we have the means to stop the epidemic. Booster doses maintain vaccination protection, and Pfizer’s Paxlovid is very effective when administered within three days after the beginning of symptoms.
While we’ve observed viral variations, we haven’t seen rapid mutation that bypasses immunity while simultaneously increasing fitness – allowing the virus to propagate more quickly and in previously infected and vaccinated populations. Even though we’re still vaccination against the original Wuhan strain of the virus and haven’t allowed updated vaccines to be used, vaccines are still effective.
The Nu version, on the other hand, is worrying.
The new variant’s @WHO name/Greek letter will be Nu (,v). B.1.1.529 is a better option. Right now, that’s about the only positive thing you can say about it. https://t.co/5D9R9Z2emk

Based on samples obtained in the middle of the month, this new South African variety was found on Tuesday. It’s been discovered in tourists from South Africa and the neighboring nations all over the globe. Flights from South Africa, Namibia, Zimbabwe, Botswana, Lesotho, and Eswatini have been halted by the United Kingdom. Along with Israel, a number of other European nations have taken similar actions.
If it is a more fit strain of the virus, that will not be enough to stop it. It will expand beyond the nations where it is presently most widespread, and from there, it will infiltrate places where planes are currently being obstructed. As we learnt during the epidemic, only island countries under complete lockdown can stop it. Furthermore, since the virus continues to evolve inside nations where it is already spreading, travel limitations will not halt the spread of mutation.
Multiple spike protein mutations have been found in this variation, which may help it become more transmissible and immune-evading. Whether or not this variety becomes dominant, it suggests that additional modifications in the virus are feasible, contradicting popular belief that major mutation would be impossible while the virus continued to infect people. Indeed, this variation eludes detection in existing testing — PCR assays can amplify three viral genomes, but only two of the genomes with this variant can be amplified. So when we say we found less than 100 examples, it’s because we weren’t actually searching for them. However, researchers discovered that patients with just their genomes amplified linked to case surges.
Regeneron monoclonal antibodies are anticipated to be less successful against the Nu strain, however AstraZeneca’s combination looks to be more effective. Meanwhile, Paxlovid, a drug developed by Pfizer, was so successful that its phase 3 study was stopped short since it was thought immoral to give anybody a placebo when they could get the real thing. The FDA, on the other hand, hasn’t said when it will be available to the public since it hasn’t yet been proven safe and effective. It’s not like we’re going to need it…
