COVID-19 Delta variant symptoms: What we know and what to look for

Vaccinations on the rise across the country

Vaccination rates across the U.S. are up this week after the CDC warned of the delta variant tand the need for vaccinated people to wear masks indoors. FOX 5's Natalie Rubino has more.

WASHINGTON - A surge by the rapidly spreading COVID-19 Delta variant is swamping hospitals, leading to new mask rules and is prompting mandatory vaccinations across the U.S.

CORONAVIRUS RESOURCES

Here’s what the Centers for Disease Control and Prevention (CDC) says about the Delta variant, its symptoms, characteristics and other things to watch for:

WHAT WE KNOW

Viruses constantly change through mutation, and new variants of a virus are expected to occur. Sometimes new variants emerge and disappear. Other times, new variants persist. Multiple variants of the virus that causes COVID-19 have been documented in the United States and globally during this pandemic. MORE ABOUT THE VARIANTS

COVID-19 cases rise in DC, Maryland and Virginia as delta variant continues to spread

COVID-19 cases are soaring across the country and are rising in parts of the D.C. region. The spike in cases is being fueled by those who aren't vaccinated and the fast spread of the delta variant, Dr. Anthony Fauci, the nation's top infectious diseases expert, said on Sunday.

Viruses constantly change and become more diverse. Scientists monitor these changes, including changes to the spikes on the surface of the virus. By carefully studying viruses, scientists can learn how changes to the virus might affect how it spreads and how sick people will get from it.

If you think about a virus like a tree growing and branching out; each branch on the tree is slightly different than the others. By comparing the branches, scientists can label them according to the differences. These small differences, or variants, have been studied and identified since the beginning of the pandemic.

Some variations allow the virus to spread more easily or make it resistant to treatments or vaccines. Those variants must be monitored more carefully.

Local leaders responding to rise of delta variant

Officials in jurisdictions throughout the D.C. area are looking at ways to respond to the rise of the delta variant.

VARIANTS IN THE UNITED STATES

The CDC is monitoring multiple variants; currently there are four notable variants in the United States:

B.1.617.2 (Delta): This variant was first detected in the United States in March 2021. It was initially identified in India in December 2020.

Delta variant, mask mandate causing concern ahead of DC Restaurant Week

D.C. Restaurant Week is just days away and it was supposed to be a celebration of the DMV coming out of the COVID-19 pandemic. However, with concerns over the delta variant and D.C.'s indoor mask mandate in effect, the service industry is once again nervous. FOX 5's Evan Lambert has more.

B.1.1.7 (Alpha): This variant was first detected in the United States in December 2020. It was initially detected in the United Kingdom.

B.1.351 (Beta): This variant was first detected in the United States at the end of January 2021. It was initially detected in South Africa in December 2020.

P.1 (Gamma): This variant was first detected in the United States in January 2021. P.1 was initially identified in travelers from Brazil, who were tested during routine screening at an airport in Japan, in early January.

Some DC bars will require proof of COVID-19 vaccination

New York City is making headlines as the first in the nation to require proof of vaccination for indoor dining, gyms or entertainment activities. Now, similar policies are popping up at bar's in the District. FOX 5's Bob Barnard has more.

These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put more strain on healthcare resources, lead to more hospitalizations, and potentially more deaths.

So far, studies suggest that the current authorized vaccines work on the circulating variants. Scientists will continue to study these and other variants.

Delta variant transmission and masks mandates

Last week, health experts shared a new study stating that the delta variant exhibits similar infection in vaccinated and unvaccinated individuals. 80 percent of vaccinated people experience symptoms from the delta variant. Dr. Ross McKinney Jr, Chief Scientific Officer of AAMC, talks to FOX 5 about the delta variant and the changes it's bringing.

WATCH FOR SYMPTOMS

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. Anyone can have mild to severe symptoms. WHEN TO SEEK EMERGENCY MEDICAL ATTENTION

People with these symptoms may have COVID-19:

Fever or chills

Cough

Shortness of breath or difficulty breathing

Fatigue

Muscle or body aches

Headache

New loss of taste or smell

Sore throat

Congestion or runny nose

Nausea or vomiting

Diarrhea

Delta variant prompts new mask requirements in DC, nationwide

Spiking COVID-19 cases nationwide are prompting a whole slew of mask mandates to return across the nation, including in Washington, D.C. Dr. Dyan Hes, medical director of Gramercy Pediatrics, joined Jim to break down what is prompting the spikes, and offers her takes on not just masking requirements, but new calls for mandatory vaccinations in some sectors.

GUIDANCE FOR PEOPLE FULLY VACCINATED

To maximize protection from the Delta variant and prevent possibly spreading it to others, wear a mask indoors in public if you are in an area of substantial or high transmission. WHEN YOU’VE BEEN FULLY VACCINATED

PROTECT YOURSELF FROM COVID-19

COVID-19 continues to spread in the United States and variants are circulating. Take steps to protect yourself from the virus. WHAT TO DO IF YOU ARE SICK

Get a COVID-19 vaccine when it is available to you.

Wear a mask that covers your nose and mouth to help protect yourself and others.

Stay 6 feet apart from others who don’t live with you.

Avoid crowds and poorly ventilated indoor spaces.

Wash your hands often with soap and water. Use hand sanitizer if soap and water aren’t available.

CDC issues new mask-wearing guidance as Delta variant cases spike

The Center for Disease Control has changed its mask guidelines for vaccinated people. Officials now saying vaccinated people in high transmission areas should wear masks indoors.
