Mt. Diablo Schools Return with Enhanced Air Quality Measures, COVID Boosters Recommended

CONCORD, CA – Mt. Diablo Unified school District students head back to classrooms Wednesday with upgraded HVAC systems designed to improve air circulation and quality,officials announced. The district is also welcoming its youngest learners, with the expansion of transitional kindergarten for 4-year-olds.

Superintendent Adam Clark confirmed the implementation of the HVAC improvements as part of ongoing efforts to maintain a healthy learning environment. Hand sanitizing stations will remain available throughout school facilities.

“we’re super excited,” Clark stated, noting the district serves approximately 30,000 students across 55 schools in seven cities.

While COVID-19 protocols have eased, public health experts continue to emphasize the benefits of vaccination. dr. Swartzberg recommends a COVID booster shot for school-aged children, stressing it’s a personal decision best made in consultation with a pediatrician.

“A booster can add protection for a child,” Dr. Swartzberg explained.

A new, updated COVID vaccine tailored to the latest viral variants is anticipated to be available in September, offering perhaps enhanced protection as the virus continues to evolve.

Beyond the Headlines: The importance of Indoor Air Quality in Schools

The focus on HVAC systems in Mt.Diablo schools reflects a growing national awareness of the critical link between indoor air quality and student health. Poor ventilation can contribute to the spread of not only viruses like COVID-19,but also common allergens and pollutants that can exacerbate asthma and other respiratory conditions.

Investing in improved air filtration and circulation isn’t just a response to the pandemic; it’s a proactive step towards creating healthier, more productive learning spaces. Experts recommend schools regularly assess and maintain their HVAC systems, considering upgrades like HEPA filters and increased outdoor air intake.

The availability of updated COVID vaccines underscores the ongoing need for vigilance and adaptability in the face of evolving viruses. Staying informed about recommended vaccinations and consulting with healthcare professionals remains crucial for protecting individual and community health.

What specific accommodations are Bay area school districts providing for students with underlying health conditions that make them more vulnerable to severe COVID-19?

Bay Area Students Return as COVID Surge Threatens School Year

Current COVID-19 Landscape in the Bay Area

As of August 5, 2025, the Bay Area is experiencing a notable surge in COVID-19 cases, driven primarily by the EG.5 variant (Eris).This increase is raising concerns as students return to in-person learning for the new school year. Public health officials are closely monitoring hospitalization rates, which, while elevated, remain lower than during previous peaks. However, the increased transmissibility of EG.5 necessitates heightened vigilance and preventative measures.Key indicators include:

Positive Case Rates: Up 35% in the last two weeks across the nine Bay area counties.

Hospitalizations: Increased by 18% but still below January 2023 levels.

Wastewater Surveillance: Showing a consistent upward trend in viral load.

Dominant Variant: EG.5 (Eris) now accounts for over 70% of sequenced cases.

School district Responses & Safety Protocols

School districts throughout the Bay Area are implementing varying levels of safety protocols in response to the COVID-19 surge.These range from strongly recommending masking to reinstating mandatory masking policies in certain situations.

Here’s a breakdown of common approaches:

1. Masking: Several districts, including San Francisco Unified and Oakland Unified, are strongly recommending indoor masking, notably for those with underlying health conditions. A few smaller districts are mandating masks for all students and staff.
2. Ventilation: Enhanced ventilation systems, including upgraded HVAC filters and increased air exchange rates, remain a priority. Many schools are utilizing portable air purifiers in classrooms.
3. Testing: Access to rapid antigen tests is being made available to students and staff, though widespread testing programs are less common than in previous years.
4. Vaccination: School districts are actively promoting COVID-19 vaccination and boosters, emphasizing the importance of staying up-to-date with immunizations. Data on vaccination clinics is being disseminated to families.
5. Sick Leave Policies: Flexible sick leave policies are crucial to encourage students and staff to stay home when feeling unwell.

Impact on Vulnerable Student Populations

The COVID-19 surge poses a disproportionate risk to vulnerable student populations, including:

Students with Disabilities: Those with underlying health conditions or compromised immune systems are at higher risk of severe illness.

Low-Income Students: Limited access to healthcare and resources can exacerbate health disparities.

English Language learners: Interaction barriers can hinder access to information and preventative measures.

Students Experiencing Homelessness: Increased exposure and limited access to hygiene facilities contribute to higher risk.

School districts are working to address these inequities through targeted outreach programs, providing access to testing and vaccination resources, and offering accommodations for students with medical needs.

Long COVID & Its Effects on Students

The potential for Long COVID – persistent symptoms following an initial infection – is a growing concern. Studies indicate that children and adolescents can develop Long COVID, experiencing symptoms such as fatigue, brain fog, and respiratory issues. This can substantially impact academic performance and overall well-being.

Symptoms: Common Long COVID symptoms in children include fatigue, headache, difficulty concentrating, and sleep disturbances.

Academic impact: Long COVID can lead to school absenteeism and reduced academic performance.

Support Services: Schools are encouraged to provide support services for students with Long COVID, including accommodations for learning and access to mental health resources.

Reduced Transmission: Minimizes the spread of COVID-19 within schools and the community.

Increased Attendance: Keeps students in school, promoting academic continuity.

Protection of Vulnerable Populations: Safeguards students and staff with underlying health conditions.

* Peace of Mind: Provides a safer learning environment for all.

Practical Tips for Parents & Students

Here are some practical steps parents and students can take to protect themselves and others:

1. Stay Up-to-Date on Vaccinations: Ensure everyone eligible is fully vaccinated and boosted.
2. Consider Masking: Wear a high-quality mask (N95 or KN95) in crowded indoor settings.
3. Practice Good Hygiene: Wash hands frequently with soap and water.
4. Stay Home When Sick: Do not attend school or activities if feeling unwell.
5. Monitor for Symptoms: Be vigilant for COVID-19 symptoms and seek
