Why are so many people coming down with Covid again?
The current wave of Covid-19 infections is being caused by
highly infectious subvariants (BA.4 and BA.5) of the Omicron variant that
entered the UK in late 2021. These subvariants are more infectious than the
previous variants of the coronavirus that the UK has faced. They are also more
likely to cause reinfections. Other factors increasing the number of infections
include greater mixing of people now that Covid-19 measures in the UK have
ended and reduced protection from infection from vaccines because many people
are more than six months since their last Covid-19 vaccination.
Are the new variants worse than the other variants?
Although they are more infectious than other variants, the
new subvariants of Omicron do not cause more severe disease and on average,
they probably cause a milder illness. However, because of the very large number
of infections caused by these subvariants, some people will have a serious
illness with a risk of being admitted to hospital or dying. The good news
though is that vaccines still work very well at reducing the risk of serious
illness and death. The number of deaths from Covid-19 in England is very low
due to this protection given by vaccines.
How bad could this new wave get?
We will see a further increase in cases and hospitalisations
during July. After July, we should see a decline in both cases and
hospitalisations as we saw with the previous two Omicron waves in January and
April. Although we will see additional pressures on the NHS, the number of
deaths will remain much lower than in January 2021 when deaths from Covid-19 in
the UK peaked.
Could any restrictions be brought back and if so, what?
It’s very unlikely the government will bring in any new
legal restrictions but they may offer public health advice on the use of face
masks in indoor settings and the importance of good ventilation in reducing the
risk of infection. They will also encourage people to take up the offer of
Covid-19 vaccination if they are eligible for a booster or have not yet had a
full course of vaccines.
Wasn’t the colder season the worst time for Covid? How
come it’s now spreading in the hot weather?
Respiratory infections are usually worse in winter when the
weather is colder and people spend more times indoors. With Covid-19, however,
we have seen new virus variants emerge that are highly infectious and which can
increase the number of infections, including in the summer.
If I’ve already had Covid this year am I just as likely
to catch this new variant, or if I do might the symptoms be milder?
People who have already had an infection this year are less
likely to get a second infection. If they do get a second infection, it is
likely to be milder, particularly if they are fully vaccinated. However, for
some people, a second infection can be more severe than their first infection.
How could the new Covid surge affect the summer holidays?
The UK government has no plans to introduce restrictions on
travel or requirements for Covid-19 testing like those we saw in previous
years. However, if there is a large increase in the number of Covid-19
infections, it is possible some countries may introduce new measures. However,
at this point, I would say this is unlikely to happen.
Will they bring back airport testing, and if not how
easily could we catch Covid if there are positive people on the flight?
There are no plans to bring back Covid-19 testing before
flights. It’s unlikely this will happen in the UK unless the number of serious
Covid-19 cases become so high, the NHS is unable to cope. The best way to
prevent this from happening is for everyone to be fully vaccinated. The risks
of catching Covid-19 are probably higher in crowded airport terminals than on
an airplane because of the ventilation and air filtration systems that modern
airplanes use. If people are unwell, they should avoid travelling so that they
do not infect others.
I’m back to working next to others in a busy office. What
precautions should I take?
Try to ensure that the room is well ventilated. Ideally,
everyone in the office should be fully vaccinated. You can also wear a face
mask (preferably an FFP2 mask that provides better protection). If anyone is
unwell with a possible Covid-19 infection, they should stay at home and not
come into work. Employers have a duty of care to their staff and should not ask
employees to come to work if they are unwell and may pass on a Covid-19
infection to others.
Am I still protected by the vaccine and booster?
If you are fully vaccinated, including with a booster, you
are still very well protected against serious illness and death, although you
can still be infected. When another booster is offered in the Autumn, you
should take up this offer if you are in an eligible group.
When will another booster be available for people under
75 and will it be updated to protect against the new variant?
Another Covid-19 vaccine booster will be available in the
Autumn. This will be offered to people living in care home for older adults and
their staff. Frontline health and social care workers and people aged 65 years
and over will also be eligible for a booster in the Autumn. Some adults aged 16
to 64 years who are in a clinical risk group will also be eligible for a
booster but the government has not yet confirmed what medical conditions will
make people eligible. There are now updated vaccines being tested that target
Omicron. The government has not yet approved these updated vaccines for use in
the UK but if the results from clinical studies are good, it’s very likely
these vaccines will be offered in place of the original vaccines for the Autumn
booster programme.
Why is there talk of an even worst Covid wave in the
Autumn? What might happen?
We had a very high number of hospitalisations and deaths
from Covid-19 in the winter of 2020-21. In the winter of 2021-22, thanks to
vaccines, the number of hospitalisations and deaths was much lower. It’s very
likely that the UK will experience another wave of Covid-19 in the Autumn and
Winter when the weather is cooler and people spend more time indoors. This increase
in Covid-19 cases may occur at the same time as a large flu epidemic. To reduce
the impact of flu and Covid-19 on people’s health and the NHS, it’s essential
that eligible people take up the offer of a flu vaccine and that as many people
as possible are fully vaccinated against Covid-19, including with any boosters
that are offered later this year.
