Understanding the JN.1 Variant: Protect Yourself with Masks and Hand Sanitizer

Understanding the JN.1 Variant: Protect Yourself with Masks and Hand Sanitizer

by ads Converclick on June 07, 2024

In early November 2023, the JN.1 variant caused less than 5% of COVID-19 cases in the U.S. Today, it is responsible for more than 60% of cases. Virologists, including Dr. Andy Pekosz, a professor in Molecular Microbiology and Immunology, are closely monitoring this variant. Here, we’ll explore what virologists are observing, the implications for case rates and treatments, and why it's crucial to use effective protective measures, including the latest face masks and hand sanitizers.

What is JN.1?

The JN.1 variant is a descendant of the BA.2.86 variant, which emerged with numerous mutations aimed at evading immunity. Although BA.2.86 did not dominate, JN.1 acquired additional mutations, enhancing its transmissibility while retaining its parent variant’s ability to evade immune responses.

Dr. Andy Pekosz explains: "JN.1 has mutated to transmit more efficiently, making it a significant concern for public health."

Current Situation with JN.1

The rise of JN.1 cases corresponds to an overall increase in COVID-19 infections. Symptoms of JN.1 are similar to those of previous Omicron variants and do not appear to cause more severe disease. However, there are indications that JN.1 might cause more gastrointestinal symptoms, like diarrhea, although more data is needed to confirm this.

Dr. Pekosz adds: "We have tools to fight COVID infection—tests, vaccines, and antivirals. Using these tools effectively is key to managing the spread."

Importance of Updated Vaccinations

Vaccination rates remain low, with only 8% of children and 19% of adults having received the latest vaccine. It's critical to boost these numbers to protect against severe illness.

Dr. Pekosz emphasizes: "The newest COVID-19 vaccine formulation is essential to protect from severe illness caused by JN.1 and other recent variants."

How to Protect Yourself: Use Face Masks and Hand Sanitizer

To safeguard against COVID-19, especially new variants like JN.1, it's crucial to use high-quality face masks and hand sanitizers.

Face Masks:

  • KN95 and N95 Masks: These masks provide superior filtration, blocking at least 95% of airborne particles. They are highly recommended for use in public spaces, especially during high transmission periods.
  • Why They Matter: According to the CDC, masks significantly reduce the transmission of respiratory viruses, including COVID-19. Using KN95 or N95 masks offers enhanced protection compared to cloth or surgical masks.

Hand Sanitizer:

  • Effective Use: Hand sanitizer with at least 60% alcohol content is effective in killing most viruses and bacteria on contact.
  • Why It’s Important: The FDA highlights that hand hygiene is one of the most important measures to prevent the spread of infections. Using hand sanitizer frequently, especially when soap and water are not available, helps reduce the risk of infection.

Dr. Anthony Fauci, former NIAID Director, notes: "Wearing masks and using hand sanitizer are simple yet powerful tools to reduce the spread of COVID-19."

Transmission Timeline of JN.1

The infectious period for JN.1 is similar to other Omicron variants. Individuals are contagious one to two days before symptoms begin and remain contagious for at least two to three days after symptom onset. Some may continue to shed the virus for up to a week.

Dr. Pekosz clarifies: "Understanding the transmission timeline helps in implementing effective isolation and preventive measures."

Reinfection and Vaccine Efficacy

Older vaccines provide limited protection against JN.1 due to the significant mutations in the virus. The updated COVID-19 vaccines, however, are designed to offer better protection against current variants.

Dr. Pekosz advises: "Annual vaccine updates are necessary to match the evolving virus, similar to influenza vaccines."

Is It Too Late to Get Vaccinated?

No, it's not too late. Getting vaccinated now can provide protection during ongoing surges. This is especially important for high-risk groups but beneficial for all eligible individuals.

Pekosz urges: "Get vaccinated as soon as possible to reduce your risk of severe illness."

Effectiveness of Paxlovid Against JN.1

Paxlovid remains effective, particularly for high-risk populations. It must be taken early in the course of infection, ideally within five days of symptom onset.

Dr. Pekosz highlights: "Early testing and prompt treatment with antivirals like Paxlovid are crucial for managing COVID-19."

Maintaining Clean Air: The Role of Air Purifiers

In addition to personal protective measures, maintaining clean air in indoor environments is vital to reduce the spread of COVID-19 and other airborne illnesses.

Why Clean Air Matters:

  • Healthier Indoor Environment: Air purifiers help remove airborne particles, including viruses, bacteria, and allergens, creating a safer indoor environment.
  • Enhanced Protection: For homes, offices, and schools, air purifiers like the Medify Air Purifier are essential in maintaining high air quality.

Medify Air Purifier Benefits:

  • HEPA Filtration: Captures 99.97% of airborne particles, including dust, pollen, and viruses.
  • Activated Carbon Filter: Eliminates odors and volatile organic compounds (VOCs).
  • UV Light Technology: Kills bacteria and viruses, providing an extra layer of protection.


The JN.1 variant highlights the ongoing challenge of COVID-19. Staying informed, getting vaccinated, using effective personal protective equipment like KN95/N95 masks and hand sanitizer, and maintaining clean indoor air with air purifiers are crucial steps in protecting yourself and others.
