A virus variant has a genome sequence that differs from that of a reference virus.

During recent months, Variants such as Lambda and Delta arise during the COVID-19 infection and transmission.

Some worries in many parts of the world right now is Delta, a highly contagious SARS-CoV-2 virus strain

Delta variant was first identified in India in December 2020.

The Delta variant is highly contagious, more than 2x the previous variants.

It swept rapidly through India and Great Britain before dominating in the U.S and now Canada

Transmissions are happening even in vaccinated individuals.

As a result, The CDC has labeled Delta a variant of concern.

Will the Delta strain make you sicker than the original virus?

A question that is yet to be answered

In two studies, patients infected with the Delta variant were more likely to be hospitalized than those infected with other virus strains.

It seems like cough and loss of smell are less common in Delta COVID disease.

Whereas headache, sore throat, runny nose, and fever are present based on the most recent surveys in the U.K

More than 90% of new cases in the U.S are due to the Delta strain.

Vaccines continue to reduce risk of contracting the virus, but Breakthrough infection can still happen in fully vaccinated people.

Studies demonstrate that vaccines remain highly effective in preventing severe illness and hospitalization.

The Pfizer-BioNTech was about 90% effective against other variants, but recent studies point at 66% efficiency against the Delta variant.

The Delta variant seems to produce the same high amount of virus in unvaccinated and fully vaccinated people.

Fully vaccinated people with Delta variant breakthrough infections can spread the virus to others.

Fully vaccinated people are found to be infectious for a shorter period
Delta Plus variant?

There are additional questions and concerns about Delta Plus, a subvariant of Delta, first identified in Europe in March 2021

Delta Plus is now detected in U.K U.S and India


The plus variant is more transmissible than the Delta variant
Delta plus is now labeled as a variant of concern by CDC.

Some studies suggest that Delta plus could easily outpace immune defenses, bind strongly to lung cell receptors.

This still requires more studies.

This mutation, called K417N, affects the spike protein that the virus needs to infect cells, which is the main target for the mRNA and other vaccines.

It is too early to conclude if vaccines are efficient against the delta plus virus
The higher the transmission rate, the higher the risk of potential exposure in public settings.

Here are some key ways to protect yourself and your loved ones:
Avoiding crowded spaces and keeping a safe distance from others.

Keeping all indoor spaces well ventilated can be as simple as opening a window.

Wearing a mask in public places where there is community transmission and physical distancing is impossible.

Washing hand regularly with soap and water or an alcohol-based hand rub.
The recent increase in infections caused by the Delta variant is an important reminder that this pandemic isn't over,

Keep updated on the level of COVID-19 transmission in your community and follow local guidance.

Even if you are vaccinated, it is still a good idea to take general safety precautions.
