Delta variant worsens pandemic

The Delta variant is putting the planet in check when we believed that vaccines would quickly end the pandemic. In countries like Indonesia there have been an absolutely dramatic explosion of cases. But also in Europe, infections have soared and alarms bells have been set off. But to what extent is this variant of the coronavirus more contagious?

1,000 times higher viral load

The logic of viruses is to refine themselves to infect more people and the Delta variant has more than succeeded: a Chinese and a British study have concluded that the viral load of this variant is 1,000 times higher than that of the alpha variant.

Each person infected infects another five people

Until now an infected person infected on average two or three individuals, whilst with the Delta variant, it infects on average five. Due to the very high viral load that we mentioned.

Extremely contagious

Another factor that causes the explosive expansion of the Delta variant is that whoever becomes infected is immediately contagious: there are experts who claim that you are contagious the same day of infection, even if there are no symptoms, the carrier can begin to infect others.

Vaccination and the Delta variant

Asymptomatic contagion also has to do with mass vaccination: those vaccinated may not get sick and, nevertheless, be contagious. In this way, a silent spread of the virus takes place.

The vaccine saves lives

However, it is crucial to convey a message: the different vaccines, although they do not stop the possibility of being infected with the Delta variant 100%, they do protect against becoming seriously ill. It is a fact that has been statistically proven by analysing hospitalisations in the United Kingdom, Spain and other European countries.

High contagiousness outdoors

The enormous viral load produced by the delta variant means that the contagion is much greater outdoors than that of the previous version of the virus. The air exhaled by someone infected, at a distance of less than two meters, can be contagious.

Do not abandon the mask

So epidemiologists ask governments that, despite the pandemic fatigue that the population are feeling, they ask for more effort and that the mask continues to be mandatory in all spaces: outdoor and indoor.

But governments (and part of the population) want to return to normal

However, in countries where vaccination has been rolling out in great numbers, there is a rush to return to normal life which is reflected, for example, in the celebrations of "Freedom Day" seen in the United Kingdom. Without masks, back to nightclubs meaning, of course, infections and hospitalisations are growing in Great Britain due to the Delta variant.

Group immunity is further away

The problem with the Delta variant's massive breakout is that group immunity is now further out of reach. According to experts if, compared to the alpha variant which forecasted that 70% of the vaccinated population stops the transmission of Covid-19; with the Delta variant it will be necessary to vaccinate at least 80% of the population.

Does the Delta variant kill more?

As for whether the Delta variant is more lethal, it appears not. Viruses do not intend to kill us but to live calmly in our organism so they tend to adapt to infect more but without making us seriously ill. However, for mere statistical reasons, the more infected, the higher the number of serious cases.

Would a new dose of vaccine help?

Pharmaceuticals are using the Delta crisis to promote the idea that a supplementary dose of the vaccine can be useful in restricting further waves of the pandemic. Israel is already doing this. However, epidemiologists do not believe this is the case, for the time being anyway.

Vaccination + mask + distance

In fact, experts believe that to put an end to the pandemic, you have to be patient and not expect a return to normality to be immediate. Mass vaccination, continuing with masks, respecting distances and restricting meetings are still the recommendations for the way forwards out of this pandemic.

The battle that has not yet been won

It is hard after so long, but the reality is that the virus has been changing and the only way to stop community transmission is by placing different layers of security (vaccination, mask, etc.)

Can new, even more contagious variants emerge?

And of course there is the need to stop infections completely, because each contagion is a possibility for the virus to mutate: the more people infected, the more options the virus has to learn how our immune system works and circumvent our defences.

Danger in poor countries

Another factor to consider is how the Delta variant can spread in poor countries and continents like Africa, where it has not yet hit that hard. Could it be a ticking time bomb?

Europe threatened

Meanwhile, in countries within Europe, it has been seen that, although deaths are falling, hospitalisations are skyrocketing.

The Stock Markets are suffering

In the emotional and economic roller coaster that has been caused by the pandemic, the Delta variant has provoked fear among investors and there continues to be days when stock markets have plummeted.

The end of the pandemic is in sight, but still not touchable

So we must assume that the conclusive end of the pandemic will be delayed, even if countries celebrate a Coronavirus Independence Day in 2021.

Fighting the Delta variant

And so the fight against the Delta variant continues in the same way the pandemic continues. But we cannot show a defeatist attitude: science knows how to defeat the virus. Just a little more effort before this disastrous episode in human history is put behind us.
