California
2 West Coast states are the first to depart from CDC’s COVID isolation guidelines
The remaining COVID-19 guidelines that still exist around the US are starting to fade away as we approach our fourth year of living with the pandemic.
Earlier this month, California’s Department of Public Health issued a formal order to change existing COVID-19 control and prevention guidelines, reducing isolation expectations for infected individuals. The introduction of the new rules, which allow people testing positive to return to public life if they are not showing symptoms, makes California the second state to break from CDC guidelines and do away with specific isolation times, following behind Oregon, which made such changes back in May.
In California’s order, issued on Jan. 9, the changes were attributed to the reduced impact of COVID compared to past years, the availability of treatment and the changing expectations to keep people most at-risk safe while posing minimal disruptions to the public.
Fact check: CDC data shows levels of COVID-19 in wastewater, not water supply
Oregon and California limit quarantine
Oregon and California are the first states to depart from the guidelines put forth by the CDC, which still recommends at least five days of isolation after first testing positive for COVID or experiencing symptoms.
Instead, Oregonians and Californians are no longer asked to isolate for a specified period after contracting COVID. Those who experience symptoms can return to work or school after just 24 hours of being fever-free, so long as symptoms are “mild and improving.” Those who experience no apparent symptoms are no longer required to isolate at all, according to the state policies.
However, both states still suggest taking precautions if you have been infected, even if you don’t have to stay home anymore. It is still advised that you avoid contact with high-risk people and mask when around others for 10 days after testing positive or becoming sick.
“We are now at a different point in time with reduced impacts from COVID-19 compared to prior years due to broad immunity from vaccination and/or natural infection, and readily available treatments available for infected people,” Director of the California Department of Public Health Dr. Tomás Aragón said in the state order.
“Our policies and priorities for intervention are now focused on protecting those most at risk for serious illness while reducing social disruption that is disproportionate to recommendations for prevention of other endemic respiratory viral infections.”
What does the CDC recommend?
The CDC guidelines still advise isolation with or without symptoms, regardless of vaccination status.
According to the guidelines, anyone who suspects they may have COVID-19 should begin isolating, even if they have not yet tested. Once testing positive, it is advised that you isolate for five days, as you are most likely to be contagious during that time.
If you test positive without symptoms but develop symptoms during the 10 days following, the isolation clock restarts. If at the end of the five days you are fever-free for 24 hours without the assistance of medication and your symptoms have improved, you may end isolation. However, if you are still experiencing symptoms with no improvement, you should wait until you are fever-free for 24 hours and/or your symptoms are improving.
People who experience more serious symptoms of shortness of breath or difficulty breathing should isolate for an additional five days, making the total quarantine time 10 days. People who had a severe illness that resulted in hospitalization or who are immunocompromised should consult their doctor about treatment plans and isolate for at least 10 days as well.
Is COVID surging again?: Surging COVID-19 cases detected in wastewater: Could it signal a new wave?
During isolation periods, the CDC suggests you:
- Wear a high-quality mask if you must be around others at home and in public.
- Do not go places where you are unable to wear a mask.
- Do not travel.
- Stay home and separate from others as much as possible.
- Use a separate bathroom, if possible.
- Take steps to improve ventilation at home, if possible.
- Don’t share personal household items, like cups, towels, and utensils.
- Monitor your symptoms. If you have an emergency warning sign (like trouble breathing), seek emergency medical care immediately.
A California man was arrested on suspicion of committing lewd acts and exploiting minors through online platforms.
The Santa Barbara County Sheriff’s Office identified the suspect as Edward “Eddie” Alessandro Zarate, 20, of Santa Maria.
On May 28, authorities began investigating Zarate over allegations that he was communicating with underage girls online and exchanging sexually explicit material with them.
Detectives later learned that Zarate allegedly communicated with minor victims through mobile phone apps such as Whipd, Purp, Wizz and Snapchat, along with exchanging text messages.
Zarate’s profiles appeared to portray him as a juvenile.
“Once he established communication with minors, he would often encourage them to move conversations off the platform and continue communicating via text message,” the sheriff’s department said. “During these conversations, Zarate would disclose his true age and identity.”
So far, authorities are aware of two female juveniles who have met with Zarate in person and reportedly engaged in lewd acts.
He is accused of communicating with minors in multiple states including California, Florida and Illinois. In California alone, detectives believe Zarate contacted minors from Los Angeles, Oxnard, Santa Barbara, San Diego, Santa Maria, Lompoc, Paso Robles, Nipomo, Arroyo Grande and San Francisco.
“Based on the scope of the investigation, detectives believe there may be additional survivors who have not yet been identified,” authorities said.
On June 10, Zarate was arrested and booked on multiple felony charges including oral copulation with a person under 18 years of age, unlawful sexual intercourse with a minor, sending harmful matter to a minor, and two counts of possession of obscene material depicting a minor.
Anyone who may be a victim, has communicated with Zarate online or through text or has information on the case is asked to call Sheriff’s Detectives at 805-681-4150. Anonymous tips can be provided to the SBSD’s tipline at 805-681-4171 or online at SBSheriff.org.
Top universities reject Trump’s ‘compact’ over academic freedom
Massachusetts Institute of Technology, Brown University, University of Pennsylvania, and University of Southern California rejected Trump’s “compact.”
To the surprise of perhaps no Californians, several California universities appeared in the top rankings of the world’s best universities in the latest U.S. News and World Report rankings released on June 16.
Of the more than 2,250 worldwide research institutions that U.S. News & World Report evaluated for this list, six California universities ranked in the top 50 globally, with an even split among Northern and Southern California institutions.
The 2026 list includes universities from more than 100 countries, with the following countries receiving the most schools in the overall rankings:
- China: 409
- United States: 275
- India: 123
- United Kingdom: 93
- Japan: 86

U.S. News and World Report methodology
When determining a university’s placement on the list, U.S. News & World Report considered factors more relevant to research-oriented institutions than to undergraduate-focused metrics like bachelor’s degree graduation rates.
It focused on aspects like academic institutions’ research and reputation, number of publications, the quality of publications and citations. It considers other factors, including location, campus culture, the strength of particular programs, and cost, which are also very important.
“For students seeking universities with strong academic excellence and global recognition, the Best Global Universities rankings offer an essential comparative resource,” said LaMont Jones, Ed.D., managing editor for Education at U.S. News.
“Our methodology focuses on a school’s research mission and scholarly impact, helping students identify institutions that are truly at the forefront of global knowledge creation.”
Out of the top 10 global universities, two California institutions made the list:
- Harvard University
- Massachusetts Institute of Technology (MIT)
- Stanford University
- University of Oxford
- University of Cambridge
- Tsinghua University
- University of California Berkeley
- Yale University
- University College London
- Columbia University
How did California colleges rank in U.S. News and World Report’s Best Global Universities 2026 list?
Outside of the top 10 universities, California saw a handful of other institutions rank highly on U.S. News & World Report list.
Notably, the University of California – Los Angeles just missed the top 10 list, ultimately ranking as the 11th-best global university and the second-best public institution on the list. It was beaten out as the best public institution by its academic counterpart, the University of California, Berkeley, which was ranked the 7th-best global university.
Additionally, a number of University of California schools made the top of the list, ultimately reaffirming the quality of the institutions’ public campuses across the state.
“Research from the University of California is vital to work that benefits all Americans, from breakthroughs in the treatment of Parkinson’s to the science behind previously unimagined successes in fighting cancer and the development of quantum computers that will enable the critical advances of the 21st century,” the University of California said in a press release about its rankings.
Here’s the list of California universities that made the top 100 list:
- 3. Stanford University
- 7. University of California Berkeley
- 11. University of California – Los Angeles
- 22. University of California – San Francisco
- 23. (Tied) California Institute of Technology
- 23. (Tied) University of California – San Diego
- 74. University of Southern California
- 95. University of California – Davis
- 99. University of California – Irvine
- 100. University of California – Santa Barbara

The most significant seismic event in California’s history – an earthquake of 7.9 magnitude – occurred in 1857 and ruptured about 225 miles on the San Andreas Fault. That earthquake, dubbed the last “Big One,” killed two people and produced shaking that lasted between one and three minutes.
Since then, California has exploded in population and been has been rattled by many major earthquakes. But Californians have also grown familiar with the existential dread of another “Big One” looming.
Researchers have long warned there will be another massive earthquake in Southern California. They just don’t know when.
A recent study says warning signs continue to grow in 2026. The San Andreas and San Jacinto fault systems have reached the highest stress levels seen in the past 1,000 years, according to a study conducted at the University of Hawaiʻi at Mānoa.
The San Andreas fault runs throughout the state, passing through San Francisco and San Bernardino, while the San Jacinto fault is in Southern California and runs through Riverside, San Diego and Imperial Counties.

Why the San Andreas Fault is so risky
Faults rupture on the San Andreas Fault approximately every 150 years, according to UCLA professor Jonathan Stewart, who studies earthquake engineering.
But it’s been over 300 years since the last “large rupture” occurred south of the 1857 Fort Tejon earthquake, Stewart said. “As far we know it didn’t produce a large rupture since around 1690. To the present that’s a lot more than 150 years, so there’s a lot of build-up. That doesn’t mean it’s going to happen immediately, it just means there is more stress built-up.”
When the earthquake happens, it is likely to cause a lot of damage. One major concern is the state’s water systems.
“An earthquake like this would rupture most, if not all of the major aqueducts bringing water into Southern California,” Stewart said. “Most people will not be in a collapsed structure after this earthquake, but everybody’s going to be affected by water problems.”
Study highlights longstanding risk
To investigate the probability of an earthquake occurring, researchers built a physics-based simulation and fed it the earthquake history from the region. By doing so, they were able to estimate how much stress has built up along the southern San Andreas and San Jacinto fault systems.
The results suggest that catastrophe may be near.
“Right now, with stress at historically high levels across the region and more than 160 years elapsed since the last major rupture, the system is in a critically loaded state,” lead author Liliane Burkhard said.
Most importantly, the Cajon Pass, at the junction of the San Andreas and San Jacinto faults, could facilitate a joint rupture of the two faults. This scenario, according to the study, would probably be “significantly more damaging” than a single-fault event.
How is earthquake safety considered?
Seismic hazard assessments are critical for the safety of the millions of residents in California’s densely-populated and earthquake-prone areas.
Seismic Hazard maps show the relative hazard associated with earthquakes using information on past faults, the behavior of seismic waves and the near-surface conditions of specific locations, according to the U.S. Geological Survey.
Larger values indicate a stronger level of earthquake shaking. A peak ground velocity of 269 cm/sec would correspond to extreme shaking and heavy damage. For reference, the largest ground velocity recorded in Taiwan’s 1999 Chi-Chi earthquake reached 318 cm/sec and had a magnitude of 6.7.
That earthquake killed more than 2,000 people and incurred approximately $14 billion in damage.
How do the fault lines rupture?
The San Andreas and San Jacinto faults are strike-slip faults, which typically cause horizontal displacement. Both faults comprise the geologic boundary between the Pacific Plate and the North American Plate.
If a major earthquake occurs on the San Andreas fault, it is likely to produce surface rupture, which occurs when a fault breaks through to the surface. Most earthquakes, however, do not produce surface rupture, according to USGS.
In a major rupture, strong shaking could cause severe damage near the fault and in areas built on soft or water-saturated soils, which can amplify shaking. Rupture can directly offset roads, buildings, and other structures that span the fault trace.
Although the study helps explain the risk associated with the California fault lines, Burkhard emphasized that it shouldn’t serve as a forecast.
“This is not a prediction of when an earthquake will happen,” Burkhard said. “However, studies like this are important contributions to national and global earthquake hazard research in that we are using rigorous, quantitative science to better understand the risk facing millions of people.”
