The 5 Mystery of Delta Variant of Covid-19

Even though people were hopeful that the pandemic would die down this year, there is still a threat that new mutations of the virus could make it come back stronger.

The most pressing concern right now is the delta variant of the SARS-CoV-2 virus, which is highly contagious and was first identified in India in December. It quickly spread through that country and Great Britain before arriving in the United States, where it is now the most prevalent strain.

So far, it looks like people who are fully vaccinated against Covid-19 are still well protected against the virus, compared to those who aren't vaccinated. However, anyone who is unvaccinated and not taking precautions is at a high risk of getting sick with the new strain, experts say.

1. Delta is more contagious than the other virus strains

Delta is spreading quickly around the world and will certainly accelerate the pandemic. The first Delta case was identified in December 2020, and the variant soon became the predominant strain of the virus in both India and then Great Britain. 

It is very alarming how fast the virus is spreading, commented on Delta's spread in the US in June. Delta was spreading twice as fast as Alpha, which was 50% more infectious than the original strain of SARS-CoV-2. In an environment where nobody is vaccinated or wearing masks, it is estimated that an individual infected with the original Covid strain will infect 2.5 other people. In a similar environment, the Delta strain would spread from one individual to as many as 3.5 or 4 others.

2. Unvaccinated people are at risk

People who are not fully vaccinated against Covid-19 are most at risk. Kids and young people are a concern as well. A recent study showed that children and adults under 50 were 2.5 times more likely to become infected with delta. No vaccine has been approved for children 5 to 12 in the U.S., although other countries have authorized vaccines for adolescents and young children.

As more people in older age groups get vaccinated, those who are younger and unvaccinated will be at higher risk of catching COVID-19 with any variant. However, Delta seems to be affecting younger age groups more than previous variants.

3. Delta could lead to hyperlocal outbreaks

If the Delta variant continues to spread quickly, the biggest questions will be about the increased contagiousness- how many people will get the Delta variant and how quickly will it spread?

The appropriate responses could depend, to some extent, on where you live—and the number of individuals in your area are vaccinated. I call it 'patchwork vaccination,' where you have these pockets that are profoundly vaccinated that are adjoining places that have 20% immunization. The issue is that this permits the infection to bounce, skip, and hop starting with one inadequately vaccinated region then onto the next.

A town with low vaccination rates that is surrounded by towns with high vaccination rates could end up containing the virus within its borders, resulting in hyperlocal outbreaks. The pandemic could then look different than what we've seen before, with real hotspots around the country.

An increase in cases would be more compressed into a shorter time frame. That actually sounds like something worth being. If too many people are infected at the same time in a certain area, the local healthcare system will become overwhelmed, and more people will die. That is something we need to worry about a lot.

4. There is still more to learn about Delta

A question of importance is if the delta strain will make you more sick than the original virus; however, many scientists say they are unsure. Early information about the severity of delta included a study from Scotland that displayed the delta variant was approximately twice as likely as alpha to land unvaccinated individuals in the hospital; though, other data has shown no significant difference.

Another inquiry centers around what Delta affects for the body. There have been reports of side effects that are not quite the same as those related with the first Covid strain. It seems like cough and loss of smell are more uncommon. What's more, headache, sore throat, runny nose, and fever are available dependent on the latest overviews in the U.K., where over 90% of the cases are because of the Delta strain.

5. Vaccination is the best protection against Delta

The most important thing you can to do to protect yourself from delta is to get vaccinated, the doctors say. This means getting both shots of a two-dose vaccine like Pfizer or Moderna and waiting the recommended two-week period for the shots to take full effect. Whether or not you are vaccinated, it is important to follow prevention guidelines that are available for vaccinated and unvaccinated people.

Throughout life, it is necessary to constantly evaluate dangers. For example, if it is sunny outside, you should wear sunscreen to protect yourself from the sun's harmful rays. If you are in a crowded gathering, you should wear a mask to protect yourself from potentially sick individuals. If you are unvaccinated and eligible for the vaccination, the best thing you can do is to get vaccinated.

There are many people who cannot get the vaccine because their doctor has advised them against it for health reasons or because individual coordinating or hardships have created barriers—or they may choose not to get it. Will the delta variant be enough to encourage the people who can get vaccinated to do so? It always is. It is not certain who encourages people with questions about vaccinations to speak to their family doctor, but it is possible.
