What leads a boom in Covid cases in India, other countries? | Coronavirus Virus News

India has reported a sudden rise in Covid, starting in late May. The authorities said that the number of active cases of the disease exceeded 5,000.

India is the latest number of countries that reach an increase in long cases this year, after more than five years of declaring virus a Global pandemicWaves New strains communication Show.

Here is what we know about the new alternative to Covid and where it has spread:

How many cases of Covid in India?

As of Thursday this week, there are 5,364 active cases in India, according to the Ministry of Health in India and the well -being of the family. Since January 1, more than 4,700 people have recovered from Covid in India, while 55 people have died of the virus.

What are the variables that cause new and where?

The main alternative is the Corona virus, which causes a new spread of the disease as NB.1.8.1. Cases caused by this alternative in the United Kingdom, the United States, Australia, Thailand, China and Hong Kong were reported among other countries. It is now the dominant alternative in China and Hong Kong.

The second alternative, LF.7, is also responsible for some cases in India.

UKSA has recorded 13 cases of NB.1.8.1 alternative in England, with “small numbers” throughout the UK.

By late April, NB.1.8.1 consists of about 10.7 per cent of the world’s series, according to the World Health Organization (WHO). This rose from 2.5 percent only one month ago.

What do we know about the NB.1.8.1 alternative?

Omicron Variant NB.1.8.1 was first discovered in January this year.

It is a “authorized” variable, which means that he originated from the genetic mixing of two or more varying.

On May 23, 2025, the World Health Organization announced that NB.1.8.1 strains “variable under observation” (VUM).

According to the definition of 2023 by the World Health Organization, VUM is the alternative that has undergone genetic changes that scientists believe may affect the behavior of the virus; Early data indicates that this alternative can grow faster or spread more easily than others, but this has not yet been confirmed.

It is still evidence of the effect of the alternative on health, immunity or transmission is unclear.

Why are there a lot of new cases?

While the NB.1.8.1 dynasty is still searching, evidence so far indicates that the strain may spread more easily, the virus world written by Lara Hero to convert on May 28.

Researchers who use the laboratory -based models have found that among many of the variables that have been tested, the new strain had the strongest ability to associate with human cell receptors. This indicates that the strain may “afflict cells more efficiently than previous breeds,” Herro wrote.

“It is more than that,” Sophash Verma, professor of microbiology and immunity at Nevada University, Faculty of Medicine, told CBS News.

What are the symptoms?

Common symptoms of NB.1.8.1 Sorel, cough, muscle, fever and nose caution include.

It can cause symptoms of the digestive system such as nausea and diarrhea.

Are Covid vaccines effective against the new strain?

Doctors say vaccines remain a strong defense against long infections, severe disease, hospitalization and death.

However, the virus world wrote Herro that besides spreading more easily, NB.1.8.1 may “partially avoid” the immunity acquired from previous vaccines or infection.

Currently, the health authorities say the current Covid death is expected to be effective against this alternative to the Coronav Virus virus and protecting people from severe illness.

Should we feel anxious?

Health experts around the world say there is no evidence that the new strain in the Coronavor virus is more severe or fatal than any previous strain. However, it appears to be more easily spread.

Since Covid spreads through air particles and drips, the virus can be prevented by testing if symptoms appear, wearing a mask and social distance, and doctors have advised.
