Covid 19 Vaccination of Seniors and Patients Being Discharged to Long Term Care Facilities
People age 65 and older and residents of long term care facilities are at the highest risk for severe morbidity and mortality from Covid-19 infection. Fortunately, the majority of our residents in these categories have been vaccinated with at least one dose of a Covid-19 vaccine and our hospitalization and death rates from Covid-19 are declining rapidly. It is imperative that we vaccinate the remaining unvaccinated individuals age 65 and older and those being discharged to long term care facilities to extend vaccine protection to these high-risk individuals to reduce the spread of Covid-19 to patients, other long term care facility residents and facility staff.

We are asking all acute care hospitals in Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, and Santa Cruz Counties to immediately institute protocols to offer Covid-19 vaccine to all unvaccinated patients age 65 and older before discharge to home as well as to all patients before discharge to a skilled nursing facility or other long term care facility.

Press Release


On February 11th, the Santa Cruz County Medical Reserve Corps (MRC) celebrated 16 years since its founding in 2005. MRC units were established after the tragic terrorist events of 9/11, and the Anthrax attacks that followed. Medical and health professionals came together to organize, train and equip local volunteers to assist Public Health and the community in emergency preparedness and response to all-hazards incidents.

Santa Cruz County MRC volunteers have responded to numerous incidents including disease outbreaks catastrophic wildfires, floods, power outages and today’s COVID-19 pandemic. Throughout the past year, MRC volunteers have supported Public Health with COVID-19 contact tracing, case investigations, infection prevention, sheltering of persons experiencing homelessness, and the CZU Complex wildfire evacuation and shelters. As vaccine has become available, MRC volunteers have been on the frontlines vaccinating disabled home-bound elders and supporting mass vaccination clinics.  Read More

Public Health Advisory

Local Guidance Regarding Communal Activities from Health Officer
The California Department of Social Services (CDSS) and the California Department of Public Health (CDPH) have released guidance allowing communal dining and some group activities under very specific conditions. Dr. Newel does not recommend these due to current widespread community disease transmission.

COVID-19 is a new virus that is still being studied and is not yet well understood. New variants are circulating which make this virus more easily transmissible. We know it can survive both on surfaces, as well as in the air, therefore any activities that increase virus in the air or on surfaces by bringing groups of people together will increase the risk of transmission.

In addition, the Health Officer's Order regarding visitation at skilled nursing and residential healthcare facilities is still in effect.

Currently the County is in the Widespread/Purple Tier of the State’s Blueprint for a Safer Economy. The Health Officer's recommendations will remain in place until we reach the Red Tier at which point facilities may consider using the CDSS and CDPH guidance. Read More

Order for Licensed Healthcare Facilities to Implement a Mandatory Influenza Prevention Program for Health Care Workers

The Centers for Disease Control estimates that in the US as many as 62,000 people died of influenza during the 2019/2020 flu season and up to 740,000 were hospitalized. Health Care Workers (HCWs) are both at risk for influenza and can transmit the virus to their vulnerable
patients. Influenza vaccination of HCWs protects medically fragile patients and reduces employee absenteeism during influenza season.

State law requires that acute care hospitals and certain employers offer influenza vaccinations to employees or have the employee sign a declination statement if they choose not to be vaccinated. While compliance to these existing laws is high, actual HCW vaccination rates are not and may be below that which will blunt the spread of infection in a health care setting. Mandatory vaccination with masking policies have been shown to increase HCW vaccination rates to above 90%. Read More

Ongoing: Local Shigellosis case cluster among persons experiencing homelessness; test & report all symptomatic patients

Current Situation:
Between December 31st, 2019, and January 2, 2020, a cluster of 3 confirmed Shigella sonnei cases have been identified at local Emergency Departments among persons experiencing homelessness. All providers should test and report any individual presenting with symptoms described below.

Between June 1st, 2019 – January 2, 2020, 34 confirmed Shigella sonnei and Shigella unspecified cases were identified in an outbreak in Santa Cruz County (more than twice the average rate). Most diagnosed Santa Cruz County cases (68%) sought medical care at an emergency department, and 41% of all cases required hospitalization.
Fifty percent of the recent cases reported experiencing homelessness. Men who have sex with men are at an elevated risk for Shigellosis. Local Shigella sonnei cases continue to exist in the general population, as well.

Shigellosis is a diarrheal illness caused by the highly infectious Shigella bacteria, and infected persons can shed up to four weeks after illness. Infections can be subclinical or self-limiting. Typical symptoms last 5-7 days and include watery or bloody diarrhea, abdominal pain, fever, and malaise. Read More

Public Health Advisory Update

UPDATE: E-cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI)

The outbreak of E-cigarette, or Vaping, Product Use-Associated Lung Injury (EVALI) has continued in California and nationwide. CDPH urges local health departments to continue reporting new or suspected cases through the identified channels currently in place.

In light of new findings that at least 25% of hospital readmissions and deaths from EVALI occur within two days of hospital discharge, CDC now recommends more stringent follow-up plans than in prior clinical guidance documents:

  • Within 48 hours of hospital discharge, all patients diagnosed with EVALI should see a primary care provider or pulmonologist in an outpatient follow-up appointment.
  • During hospitalization and follow-up, EVALI patients should be offered support for cessation of e-cigarette, or vaping use.
  • Prior to hospital discharge, EVALI patients should be clinically stable for 24-48 hours.

Public Health Officials Announce "It's Time to Get Vaccinated for the Flu!"

The County of Santa Cruz Public Health urges everyone six months and older to get vaccinated early before the virus starts going around. The flu vaccine helps stop the spread of the flu and protects everyone’s health. The start of the flu season is unpredictable, and the vaccine takes two weeks to become fully effective.

Vaccines are available at doctors’ offices, and many pharmacies provide free and low-cost flu vaccinations to the public.

“Flu shots are the best way to protect yourself, your family, and the community from becoming seriously ill with the flu,” said County Health Officer, Dr. Gail Newel.

It is important to get the flu vaccine every year because flu strains change over time. Timely flu shots help prevent a disease that hospitalizes hundreds of thousands and kills tens of thousands of Americans every year. Read More

Opioid Overdoses from Fake Pills
You may have recently seen a “public health warning” regarding fake pills containing the powerful and deadly fentanyl. We are writing to provide additional information, guidance and context. These counterfeit pills have been found in neighboring Santa Clara and Monterey Counties. The following memo provides information about naloxone and guidance on talking with youth.

Why Is This Important?
Fentanyl is a very powerful opioid drug — 80-100 times more powerful than morphine — and exposure to even small amounts can cause overdose and death. The County Medical Examiner has reported 44 opioid deaths* from January 1, 2019 to August 31, 2019. Of the 44 deaths, 11 have involved fentanyl, including those of a 15 and 16-year-old. Several of these deaths have been linked to these fake pills containing the chemical fentanyl, made to look like a 30 mg oxycodone prescription pill (Percocet®). People who took these pills thinking they were taking oxycodone were unaware that they were taking lethal doses of fentanyl. Read More

Increase in Shigella Cases and Antibiotic Resistance

Current Situation: Santa Cruz County Public Health notes that the number of reported Shigella sonnei cases in the first eight months of 2019 is double the average annual count between 2016 and 2018 – excluding outbreaks (21 vs 10). Persons experiencing homelessness (PEH) and men who have sex with men (MSM) are particularly burdened, though Shigella sonnei cases continue to exist in our general population. Emerging evidence shows reduced susceptibility to ciprofloxacin and azithromycin (see “Actions” and “Additional resources” below). Transmission occurs easily via the fecal-oral route, and sexual transmission is known to occur. Consider testing patients with Shigella for sexually transmitted diseases (STDs) and HIV; more than 20% of our recent shigellosis cases are living with HIV. Read More

Vaping-Associated Pulmonary Injury

Current Situation: A Health Advisory has been issued for lung injuries related to vaping cannabis, cannabis oils or nicotine products in Santa Cruz County after the California Department of Public Health (CDPH) issued a statewide Health Alert. There are currently no cases of vaping-associated lung illness reported in the County, however Health Officer, Dr. Gail Newel, has requested local clinicians to watch for symptoms, inquire about use of vaping products, and report any suspected cases.

Since June, 36 cases of vaping-associated lung illness requiring hospitalization were reported in California. In Kings County, located in California’s Central Valley region, seven patients experienced trouble breathing that worsened after an initial diagnosis of pneumonia or bronchitis. Those patients reported vaping cannabis or cannabis-based oils in the weeks prior to hospital admission and failed to respond to antibiotic treatment. Medical tests for infectious disease were negative. Read More

Clinicians who identify cases similar to those described in this health alert are asked to report the cases to the Santa Cruz County Communicable Disease Unit at (831) 454-4114.

Background: Vaping refers to the practice of inhaling vapor from an e-cigarette device, which works by heating a liquid that can contain nicotine, marijuana, or other drugs. The long-term health impacts of vaping are unknown. The liquids used in e-cigarettes can contain toxic chemicals that can cause lung damage.

Public Health Departments Urge Vaccination Before International Travel

As travel season approaches, Santa Cruz County residents should ensure they are protected against measles. Nationwide, measles cases now total 704 in 2019, the highest since 1994. Nearly all these cases have been linked back to international travel by unvaccinated people and subsequent spread in unvaccinated populations in the U.S. So, protection against measles is especially critical for those who plan to travel internationally and for those in communities that might have lower vaccination rates.

“Measles is a highly contagious and potentially serious disease. In the U.S., about 1 in 4 people who get measles will be hospitalized. Luckily, measles is also preventable through a safe, effective, and widely available vaccine,” Jennifer Herrera, Santa Cruz County’s Director of Nursing. “The vaccine protects you as well as vulnerable babies and community members with medical conditions who can’t be vaccinated.”

For both adults and children, completing the recommended two doses of the measles, mumps, rubella (MMR) vaccine is the best protection against measles. The Centers for Disease Control and Prevention (CDC) recommends two doses of MMR vaccine for everyone: the first dose at 12-15 months of age and the second dose at 4-6 years of age. If you are unsure of your immunization status consult with your doctor. Adults should get vaccinated for measles if they did not receive the two doses as children. Read More

Take Charge of Your Sexual Health: Get Tested
Young people encouraged to get tested for STDs

April is sexually transmitted disease (STD) awareness month. STD prevention and testing are critical to overall health.

STD Awareness Month is not just about awareness but also about action. Local health officials urge everyone who is sexually active, especially young people, to take charge of their sexual health and get tested. Young people and men who have sex with men are at particular risk and should get tested more often.

STD testing is now more crucial than ever because rates continue to rise in Santa Cruz County and statewide. Rates of chlamydia, gonorrhea, and syphilis continue to grow, and syphilis has re-emerged as a significant public health concern. Still, all STDs can be prevented and treated, and most can be cured.

Measles Outbreak in Washington and Oregon

A large measles outbreak is occurring in Washington state and Oregon. From January 1-28, 2019, there have been 35 confirmed cases of measles in Clark County, WA. Children aged 1-10 years comprise 25 of these cases while 9 cases are aged 11-18 years. Importantly, 89% (31) of the cases are unimmunized for measles and 4 cases have unverified immunization status. Two additional cases linked to Clark County have been confirmed in King County, WA and Multnomah County, OR. Local health departments in each county are conducting contact investigations with support from the Washington State Department of Health.

Measles is a highly contagious and potentially serious illness caused by a virus. The virus can linger in the air for up to two hours after an infectious person has left. Airborne transmission can easily occur in congregate settings like healthcare facilities, schools, childcares, shopping centers, public transportation, airports, and amusement parks. Clinicians should be vigilant in identifying and managing suspected measles cases to avoid ongoing transmission. It is also very important to ensure that patients and staff are up-to-date with immunizations. Read More

Local Increase in Pertussis (Whooping Cough) Cases

The number of pertussis (whooping cough) cases continues to increase across Santa Cruz County. Since September 1st, the Public Health Division has received 66 reports of suspected or confirmed pertussis cases, with most cases associated with multiple school outbreaks.Public Health officials recommend that providers be vigilant in evaluating individuals for pertussis, particularly those in close contact with infants and pregnant women as whooping cough can progress to severe symptoms, including death, in infants less than one year old. Be aware that early symptoms may resemble a common cold and that vaccinated individuals may present with milder symptoms.

Due to the recent events, Santa Cruz County Public Health officials recommend that local medical providers consider pertussis in any individual presenting with a progressive cough illness lasting longer than one week, particularly if posttussive vomiting and/or paroxysmal coughing occurs. Be aware that early symptoms may resemble a common cold and that vaccinated individuals may present with milder symptoms. Read More

Ongoing Ticks and Tick-Borne Diseases

Spring is a time of high tick activity in our coastal hills and residents should be aware when spending time outdoors. Santa Cruz County Mosquito and Vector Control (SCCMVC) staff and the California Department of Public Health (CDPH) collaborate to collect and test ticks in the County. At least 2% of Western black-legged ticks (Ixodes pacificus) tested in recent years contain the bacteria that can cause Lyme disease. In 2013, there were 5 reported cases of Lyme disease in Santa Cruz County, about the annual average (1.66 cases per 100,000 people).

The western black legged tick (Ixodes pacificus) and other human biting ticks found in Santa Cruz County such as the Pacific Coast tick (Dermacentor occidentalis) may carry other tick-borne diseases. Thus, SCCMVC plans to conduct surveys for these tick species and will submit them to the CDPH for testing. Because of tick-borne disease risk, residents are advised to take precautions to protect themselves from tick bites.

The tick starts out as an egg then matures into a larva, nymph and adult stage over several years. The nymph life stage is active in spring and summer, and is found on tree trunks, fallen logs, wooden benches and in leaf litter and feed on smaller animals, but they will also attach to people and pets. Adult ticks are active in fall when they climb to the tips of vegetation, often alongside trails or paths, and attach themselves to hosts, such as deer, pets or humans that brush against them.

Ticks feed by sticking their mouthparts into the skin of their host and sucking blood. Infections such as Lyme disease may be transmitted when the feeding tick is attached for at least a day. Immature ticks are about the size of a pinhead, and may be missed without careful examination.

The risk of being bitten by ticks may be reduced with the following precautions:

  • Wear long pants and long-sleeved shirts. Tuck pant legs into boots or socks and tuck shirts into pants.
  • Wear light-colored clothing so ticks can be easily seen.
  • Use a repellent registered for use against ticks; always follow label directions.
  • Stay in the middle of a trail and avoid logs, tree trunks, trail margins, brush and grassy areas.
  • Inspect yourself frequently while in tick habitat. Once out of tick habitat, thoroughly check your entire body and pets. Parents should examine their children, especially on the scalp and hairline.
  • Shower and launder clothes soon after activity in tick habitat.

To reduce the possibility of infection, remove attached ticks as soon as possible. Gently and firmly grasp the tick close to the head and pull it straight out, preferably with a tick tool or with fine-pointed tweezers. Save the tick for identification. Ticks should be kept alive by placing the tick into a sealable bag or container with a moist cotton ball in a refrigerator or cooler. The person removing the tick should wash their hands before and after removal and apply antiseptic to the bite area. Insecticides, Vaseline, lighted matches or gasoline should not be used to remove ticks because these techniques are ineffective or unsafe. Anyone who develops symptoms after being bitten by a tick should consult his or her physician.

Painful redness that occurs less than 24 hours after a tick bite and does not expand is likely a local allergic reaction to the tick bite. Early Lyme disease also has a rash but the Lyme disease rash appears three to 30 days after the tick bite, is often painless, and spreads to greater than 5 cm in diameter. The spreading rash can be accompanied by flu like symptoms, such as fever and body aches. Lyme disease is treated with antibiotics and most patients recover without complications, particularly when the disease is diagnosed early. If left untreated, Lyme disease can progress to arthritis and in some cases serious nervous system problems.

Individuals should consult their physician immediately if symptoms similar to those described for Lyme disease develop within one to several weeks after being bitten by a tick.
