Understanding Latest COVID Variant Symptoms in 2023

Understanding New COVID-19 Variants in 2023

As we enter 2023, COVID-19 remains an ever-present threat, with new variants continuing to emerge. The latest data shows that the Eris variant now accounts for over 70% of cases globally. While infection rates remain high, recent evidence suggests hospitalization rates are slowing as immunity builds through vaccination and prior infection.

Nevertheless, the unpredictability of new variants means we must remain vigilant regarding potential symptoms. Understanding the latest data can help individuals make informed decisions about protecting themselves and others.

Tracking Emerging COVID-19 Variants

Global surveillance by organizations such as the WHO and CDC tracks new SARS-CoV-2 variants and monitors their growth. This allows us to spot concerning new variants quickly and take appropriate public health action if needed.

Variants undergo genetic changes called mutations that can increase transmissibility, disease severity, or ability to evade immunity. Those meeting criteria as Variants of Concern or Interest are closely watched.

Eris Continues Its Dominance

The BQ.1/BQ1.1 subvariants of Omicron, together called Eris, now cause a large majority of cases globally. Preliminary evidence suggests it spreads faster than BA.5 but may not cause more severe disease.

Vaccination remains highly effective against severe disease and death, even from Eris infection. However, as a highly mutated variant, it has greater ability to infect those with prior immunity. Continued uptake of bivalent boosters can strengthen defenses.

Understanding Common Symptoms

Despite new variants, COVID-19 generally causes similar symptoms:

• Cough
• Fatigue
• Fever
• Body aches
• Shortness of breath
• Sore throat
• Loss of taste/smell

However, some data suggests that common symptoms are changing over time. Less cases involve loss of smell now compared to early 2020. Flu-like symptoms such as fever, fatigue, and body aches appear more prominent.

Monitoring for New or Atypical Symptoms

Experts closely monitor real-world data for symptoms reported with new variants. For Eris, symptoms appear typical so far, but vigilance remains important.

Any new, unusual, or multiplied symptoms should warrant testing. These may include:

• Rashes
• Conjunctivitis
• Severe nausea/vomiting
• Severe chest pain

Bivalent boosters target Omicron subvariants, helping strengthen defenses against variants like Eris with noticeable mutations versus original strain. Vaccines still prevent most severe disease and remain a crucial tool.

Interpreting Testing Results

Molecular tests that detect viral RNA, including common PCR tests, can identify current SARS-CoV-2 infection. However, they cannot distinguish which variant caused infection.

To identify variant strains, samples undergo specialized genomic sequencing – a complex process requiring specialized equipment and analysis. Rapid antigen screening tests are also unable to confirm specific variants.

Since Eris causes most current cases, a positive test likely indicates Eris infection. However, without sequencing, a negative on either PCR or antigen test may miss some infections.

Behavioral Factors Impacting New Variants

Viruses naturally mutate and evolve over time, leading to new variants. But human factors also play an important role influencing the spread of variants like Eris.

Pandemic Fatigue

After approaching three years living with COVID-19, many suffer from pandemic fatigue – exhaustion with complying with personal protective behavior like masking. However, relaxing such precautions allows increased viral spread and mutation.

Large Conferences and Gatherings

Business conferences, political events, holiday celebrations, concerts, and sporting events facilitate superspreader-type scenarios. With travel also continuing, variants can spread rapidly across geographic boundaries.

Isolation Rule Breaking

Isolation rules exist to slow viral transmission of highly contagious diseases like COVID-19. But adherence remains inconsistent – further enabled by lack of paid sick leave policies.

Pressuring employees to return before ending isolation also propagates spread. Remote work options facilitate better compliance when possible.

Looking Ahead with COVID-19 Variants

With Eris causing renewed waves of infection, COVID-19 continues to present unpredictable challenges. However, hope exists that infection severity may decline over time.

Transition Towards Endemic Status

Many experts expect COVID-19 to transition eventually from pandemic to endemic status, circulating persistently but causing less severe outcomes. However, the timing remains uncertain and difficult to predict.

Nevertheless, factors like rising vaccination rates, improved treatments, partial natural immunity, and potentially falling virulence provide reasons for some optimism moving forward.

Role of Vaccine Technology

The fast arrival of mRNA vaccines catalyzed the response against COVID-19. This technology offers easier and faster adaptation to new viral strains. Future multivalent vaccines could target dominant circulating variants, including Eris and beyond.

Ongoing research also explores pan-coronavirus vaccines for protection against the entire virus family, lowering risk from novel strains.

Therapeutics and At-Home Testing

Antiviral pills and monoclonal antibody treatments also continue advancing, offering better early treatment options over time. Easy access to rapid tests facilitates quicker action if infected.

Such innovations further accelerate the transition towards managing COVID-19 as an endemic virus akin to seasonal influenza rather than an overwhelming pandemic threat.
