Why You Still Need to Take COVID-19 Seriously

Cases of infections are skyrocketing across the U.S.

With cases of COVID-19 rising in parts of the country, it can be frustrating and scary to still be dealing with the pandemic after almost two years.

But as new variants like delta and omicron become the dominant strains in the United States, it remains important for all of us to do our part to keep ourselves and each other safe.

Even if you’re vaccinated, received your booster and have been practicing social distancing, now is not the time to let your guard down.

Pulmonologist and intensivist Eduardo Mireles-Cabodevila, MD, talks about why we’re still in the middle of a pandemic and what we can do to stay safe.

“We need to keep our guard up because what we’re seeing right now has been caused by relaxed social distancing,” says Dr. Mireles-Cabodevila.

Why are we still here?

Throughout the last two years, tools like at-home COVID-19 testing kits and vaccines have helped us manage the COVID-19 virus.

At times, the number of cases of COVID-19 infections has decreased, but not enough for the World Health Organization (WHO) to declare the pandemic over.

“There’s moments in which the numbers go down and it allows hospitals to be able to manage and take care of patients in the ICU,” says Dr. Mireles-Cabodevila. “It allows people to have a social life and do business as usual. But right now, we’re not there.”

A pandemic is when a disease’s growth rate skyrockets, with more cases each day than the last.

We won’t enter an endemic, a phase when a disease is limited to a particular region, until the rates and spread are predictable.

Even with vaccines and boosters available, many hospital systems across the country are seeing high numbers of patients in their intensive care units (ICUs), with the majority of them unvaccinated.

The best way to protect yourself and others is to get vaccinated. If you’re due for your booster shot, have been undecided about getting your child vaccinated or have been weary all along about getting a vaccine, the science is clear: Vaccines save lives.

“We need the vaccine to go into the arms of people so that we’re able to protect them for the future,” says Dr. Mireles-Cabodevila. “That way, they can get back into real life and we can stop the spread of this virus.”

Why you should still take COVID-19 seriously

We understand; it’s been tough dealing with social distancing, canceling events and not seeing loved ones over the last two years. But even if you’ve been doing everything right, stay the course.

“If you’re vaccinated and you come in contact with the virus, you may not get ill, but you can spread it,” says Dr. Mireles-Cabodevila. “Then, if you’re in contact with somebody who is vulnerable, you have a situation in which you have caused harm to somebody else.”

So it’s important to keep doing the following:

  • Wash your hands.
  • Wear a mask.
  • Limit indoor gatherings.
  • Stay home if you feel sick.

What are variants?

Variants like delta and omicron have been making headlines lately. Viruses like COVID-19 adapt and mutate over time, leading to a variant that could be stronger and can spread faster.


“The virus that we’re seeing right now is not the same virus that we saw in February 2020,” says Dr. Mireles-Cabodevila. “The new variants that are coming out seem to be more contagious than the others, so they spread really rapidly.”

Omicron, the latest variant, seems to spread faster. If you’re vaccinated and get infected with a breakthrough case of COVID-19, these new strains may only result in minor symptoms and many people can recover rather quickly.

“However, the sheer number of people who get the disease increases the amount of people who get severe disease. That’s when it starts overwhelming the healthcare system,” says Dr. Mireles-Cabodevila.

Vaccines protect you against severe disease. Getting a booster increases immune response and reminds your body of how to fight COVID-19 and its variants.

Even if new variants appear, having a defense system activated by vaccines will have you covered better than not being vaccinated at all.

And there may yet be more variants of COVID-19 — unless we all take the pandemic seriously.

“The number of variants that we will see in the future depends on our actions of today,” says Dr. Mireles-Cabodevila. “Every time that the virus infects somebody, it has a chance to mutate. Vaccination is best. The less it spreads, the less chance it has to mutate.”

What to do if you have been exposed or infected

So, thinking you might have been exposed or infected with COVID-19? First, make sure you wear a mask and separate yourself from family, friends and co-workers.

Next, get tested. Although many people have had trouble finding at-home COVID-19 rapid test kits lately due to supply shortages, tests may be available to buy at drug stores and pharmacies or obtained for free at your local library. President Biden has also promised to purchase 500 million at-home COVID-19 rapid tests, which will be distributed for free to Americans who want them starting in early 2022.

Don’t go to the emergency room for a test, though. ERs across the country are currently overwhelmed and have people waiting to get into the hospital for care.

But if you’re experiencing the following, head to the nearest emergency room or call 911.

  • Difficulty breathing.
  • Confusion or disorientation.
  • Severe chest pain or tightness.
  • Bluish discoloration of your skin, lips or nails.

“COVID-19 has no preference. It goes after people of any race, any gender, any age,” says Dr. Mireles-Cabodevila. “We have to protect our communities and our families by doing the responsible thing. Wear a mask and vaccinate yourself because you can help tremendously in controlling the pandemic.”
