A new very aggressive variant with disturbing symptoms?

1. Tdn >
2. &#13. Nevertheless, Health

After the Delta or Omicron variants, a new variant of the COVVIR progresses in France. Furthermore, Le Covid “rainstorm”much more contagious, strongly worries doctors. However, And, for good reason, its symptoms would be particularly painful and dangerous. Nevertheless, We explain to you.

COVVI-19, a dangerous virus that can become mortal – New very aggressive variant disturbing

COVVI-19 is a public health issue. Similarly, Everyone now knows: this virus can be very dangerous. Consequently, Very contagious, we can easily catch itbeing in contact with a contaminated person and even with a contaminated surface.

But, what worries the most when we talk about this disease are symptoms, sometimes new very aggressive variant disturbing very aggressive. Furthermore, Although some people are asymptomatic, most patients describe a influenzaheadaches, feverdiarrhea, fatigue and loss of smell.

But, the symptoms depend on each. However, Among the patients, some also have coughs and have breathing difficulties. In addition, In some cases, these breathing difficulties can lead to emergency, intensive care and sometimes the patient’s death. However,

6 million people lost their lives in August 18, 2023, because of the virus, of which 160,000 in France. Therefore, So, yes, the covid can really have terrible consequences, depending on the symptoms. However, The weakest are the most at risk (elderly, sick, children, pregnant women, etc.).

The very new very aggressive variant disturbing vague origin of the coronavirus

The COVVI-19 is a virus from a well-known virus class of science. Therefore, But, until 2019no case had been observed on humans, only on animals. Moreover, the virus was observed by various laboratories, taken from animals.

It is in Chine that the world epidemic begins. However, its precise origin remains very vague. Therefore, Officially, the first contaminated patient would have consumed a contaminated animala bat or a pangolin.

But, according to American authorities, it would be possible that this virus was escape a laboratory Very secure in China. Nevertheless, For the moment, this thesis is highly criticized. Nevertheless, But, what is certain is that the virus has done a lot of damage.

A disease that has changed our lifestyle – New very aggressive variant disturbing

Damage to the health level, with a lot of death, but also damage social and economic. With the pandemic, many countries have invested massively in the health sector. And, in parallel, there were also the confinements.

During the confinements, the country was stopped. THE non -essential shops were closed. which also caused the closure of many establishments, still shunned new very aggressive variant disturbing while the covid is less virulent today (for example, nightclubs).

If we found a globally normal life today, we could not go out without compulsory certificate, the mask was compulsory and the social distancing has greatly changed our current lifestyles.

After the confinements. Social isolation has grown up, generalized anxiety has gained ground, hypocondria and OCS (as excessively washing) stormed the population. new very aggressive variant disturbing Finally, with confinements, e-commerce also nibbled from the field, to the detriment of stores.

Despite the immune defenses, the virus quickly matt

Today, the virus is less virulent and we have generally resumed the course of our life. For this, we can thank the vaccination campaigns, but also Collective immunity. Except that, the covid is still present and far from disappearing.

To survive in the new very aggressive variant disturbing face of vaccination. collective immunity, the virus is constantly puts on to better adapt to its hosts. And, the variants are more and more contagious, sometimes passing under the immune barriers.

Besides, some believe that we are going to live from new waves This summer 2025, and some even speak of a reconfirma in July. Among the variants, there was for example the Delta variant or new very aggressive variant disturbing the variant Omicron, who had really been talked about.

But the more the virus spreads, the more it mute in new variants. And even if other contagious diseases continue to rage in France, COVVIR remains a major concern. Especially since one of its new variants would cause very annoying symptoms.

COVID NIMBUS worries doctors

Right now, the virus rainstorm Progress very quickly new very aggressive variant disturbing in the world and in France. More particularly its Stun NB.1.8.1. This strain is one of the descendants ofOmicron. Only, this strain seems very contagious and much more painful.

Currently, this variant would have been detected in approximately 22 pays and several cases have been detected in the City of LyonIn France. It was then in May 2025, but the virus continued to progress in June 2025. “A dozen carriers of NB.1.8.1 were detected in France”explains the world.

“In particular in Auvergne-Rhône-Alpes and New Aquitaine. The indicators on the virus. if they remain at very low levels, have been increasing for three weeks ”, added the site. And, now, The World Health Organization (WHO) observes it very closely.

The cases are currently treated by the National Reference Center of Lyon, but it could be that several cases have not yet been detected.

At BFMTV, Virologist Bruno Lina explains: “There are a number of countries that have reported it. We found a little in France, not much, four sequences that were found, both in the hospital and in town« .

A strain that passes under immune barriers?

“From what we seem to know about the virus. for the moment, is that it seems capable of be over the immune defenses acquired in contact with other variants. Thus, this variant therefore seems easier to catch ”, Explain in an article dedicated to this strain.

« Il faster in cells faster and reproduces. […] Its specificities probably prefigure that this varying of the virus becomes new very aggressive variant disturbing the majority in the future ”, We read at BFMTV. The virus would therefore be able to cross the immune barriers and would therefore be more contagious.

“According to the specialist interviewed by La Dépêche. the virus seems to benefit from increased transmissibility and better ability to go around immunity acquired naturally or thanks to vaccines ”, We also read at La Dépêche.

“These characteristics explain the outbreak observed in Asia. could promote a Quick spread this summerperiod traditionally conducive to international trips ”, Then adds the media.

Very painful and dangerous symptoms?

But the worst part is its symptoms. “According to Dr. Naveed Asif. this lively and localized pain at the bottom of the throat can be the sign of an infection in variant NB.1.8.1. He talks about a sharp feeling of swallowingdescribed by patients as unbearable and sudden ”, explained this site.

This strain would therefore cause important throat painalmost like a “Pasoir blade”. At Salon, Dr. Mohamed Imran Lakhi also talks about other disturbing symptoms with this strain.

“Some also suffer from digestive problems such as nausea. diarrheawhich is not a typical symptom of variants of the covid new very aggressive variant disturbing ”, explains the doctor.

WHO tempers speech and reassures

The WHO seems very worried about the issue. Moreover, the organization recently published a press release, ranking Nimbus among the variants under surveillance. Despite everything. WHO decided to temper the speech and reassure:

“Despite a simultaneous increase in cases and hospitalizations in certain countries where the variant NB.1.8.1 is present. current data do new very aggressive variant disturbing not indicate that this variant leads to a disease more serious than the other variants in circulation ”, said the health institution.

A potential risk for this summer

Edoardo COLZANI. head of respiratory viruses at the ECDC, also prices the floor in a press release. “The SARS-COV-2 is currently circulating at low levels in the EU/EEE. but its incidence could increase in the coming weeks”, he said.

« We do not plan that the variant NB.1.8.1 presents a more important risk new very aggressive variant disturbing for public health than other variants from omicron. and we also do not provide for significant impact on the effectiveness of the vaccine against the serious forms of the disease ”he added.

“However, after a winter marked by a low circulation of Sars-Cov-2, the immunity of the population Against the SARS-COV-2 could have partially decreased, especially in the elderly and other people presenting a higher risk of serious form« , he explains.

In other words, for the moment, this strain seems disturbing and is under surveillance. It is possible to reduce immune efficiency and it is therefore more contagious, sometimes causing very annoying symptoms. However, the current data do not allow us to say if it presents a greater risk.
