Winter appears like it’s going to be robust. Instances are rising throughout the entire of the UK, the restrictions on our lives are already tightening, there are fears some hospitals are beginning to refill and there are ongoing political and scientific rows.

It looks like there’s a fixed stream of knowledge and you’ll be forgiven for getting misplaced within the whirlwind of headlines.

So – let’s hold this actually straight and actually easy. The place are we, is that this a repeat of spring and the way apprehensive ought to we be?

Covid remains to be largely delicate

Do not forget the overwhelming majority of individuals do get well from Covid and it’s usually a light illness.

The primary signs are a cough, fever and a lack of sense of odor and most will recuperate at residence.

It’s estimated that

1% to three% of people that catch the virus require hospital remedy.

However it’s extra lethal than flu

The variety of people who die after catching the virus, referred to as the an infection fatality fee, is about 0.5%. Or one demise in each 200 individuals contaminated.

That’s 5 to 25 instances extra lethal than a seasonal flu an infection, regardless of ongoing myths that Covid is rather like flu.

Influenza kills between 0.02% and 0.1% of people who find themselves contaminated.

Some individuals are at greater threat

Folks of any age can die from Covid, however the dangers are greater the older you’re.

Solely a tiny fraction of individuals underneath the age of 45 die after catching the virus and the chance actually picks up after the age of 65.

Folks with different well being issues – corresponding to sort 2 diabetes and coronary heart issues – are additionally at greater threat.

As are individuals from sure ethnic backgrounds.

The numbers are all going up

The statistics inform a grim story.

The variety of day by day circumstances – up. The variety of individuals being admitted to hospital – up. The variety of individuals dying – up.

We aren’t on the identical degree we have been on the peak, when 3,000 individuals have been being admitted to hospital with Covid every day. It’s presently under 1,000.

So it is a drawback of trajectory.

The concern is rising circumstances may finally overwhelm the NHS. If that occurs then extra individuals will die, from Covid and different causes, as a result of there will not be sufficient beds and docs to go spherical.

However the virus is spreading extra slowly than earlier than

The issues we are actually doing in our day-to-day lives are making a distinction to the unfold of the virus.

Initially of the pandemic, the variety of individuals being contaminated was doubling each three-to-four days. The doubling time is now nearer to each fortnight.

The replica or R quantity – the variety of individuals every contaminated particular person passes the virus onto on common – was about 3.0 throughout the UK early March. It’s now about half that (between 1.3 and 1.5).

We’re making a distinction, however any development remains to be development and until the R quantity comes under 1.0, the variety of circumstances, and in flip strain on hospitals, will proceed to rise.

We’re higher at treating Covid

The possibility of dying if you’re admitted to hospital has fallen for the reason that begin of the pandemic.

Getting a exact estimate is tough, however the demise fee in hospitals appears to have fallen by between a 3rd and a half.

Medical doctors have a greater understanding of what occurs to extreme Covid sufferers, corresponding to creating unusually sticky clot-prone blood. Meaning care has improved.

And we now have the primary life-saving drug, a steroid referred to as dexamethasone that calms the immune system when it turns into overactive and assaults the physique.

However we should not ignore ‘lengthy Covid’

Nonetheless, there may be rising recognition {that a} coronavirus an infection can take an enduring toll on the physique.

We do not understand how lengthy or precisely how many individuals are affected, however long-term fatigue and a complete host of different well being issues have been reported.

These signs seem to have an effect on younger and previous, in addition to those that had even delicate infections.

You are most likely not immune

Most individuals haven’t been contaminated with the virus. About 9 in 10 of us within the UK are thought to nonetheless be susceptible.

Getting Covid twice is uncommon. Nonetheless, no one is sort of positive how lengthy any immunity from combating off the virus would possibly final.

We’re nonetheless ready for a vaccine

An efficient vaccine would both cease individuals getting contaminated or at the very least make the illness much less extreme.

Progress is being made, however none has but been confirmed to work.

A vaccine stays one of many key instruments for getting our lives again, till then the federal government’s technique is counting on slowing the unfold of the virus and meaning restrictions on all our lives.

Check-and-trace is struggling

The opposite measure that was supposed to assist suppress the virus was the federal government’s test-and-trace programme.

Testing capability has elevated dramatically for the reason that starting of the pandemic and there are actually greater than 300,000 checks a day being carried out.

Nonetheless, the programme works greatest when ranges of the virus are low and the federal government’s personal science advisers, Sage, say test-and-trace is having a “marginal affect on transmission”.
