SAN DIEGO (KGTV) — There are still many unknowns surrounding SARS-CoV-2, the official name of the new coronavirus, but almost from the beginning one thing has been clear: people with underlying health conditions are more at-risk.San Diego County Health officials released new data this month showing which underlying conditions pose the greatest risk of death from COVID-19, based on the number of times a condition was listed on death certificates and other medical records.Among the 626 COVID deaths recorded in San Diego County as of Tuesday, 96 percent of the victims had at least one underlying condition. Only 4 percent, or 27 people, died without evidence of an underlying condition.Hypertension (high blood pressure) -- listed in 50% of deathsDiabetes -- 35%Cardiac Disease -- 31%Dementia/Alzheimer’s -- 27%Chronic Kidney Disease -- 18%COPD/Asthma -- 13%Obesity -- 8%Immunocompromised -- 5%No underlying condition -- 4%So what makes these conditions more risky than others? It may have to do with the prevalence of these conditions in the population and the way SARS-CoV-2 attacks the body, according to Sharp Rees-Stealy physician Dr. Abisola Olulade.Scientists are still scrambling to understand exactly how SARS-CoV-2 attacks and kills patients, but emerging research offers some theories.It starts when virus particles enter a person’s nose or mouth. The coronavirus makes it way towards the lungs first, and the immune system tries to fight it, causing inflammation along the way that can lead to pneumonia.People with hypertension and diabetes, the top two underlying conditions in San Diego County’s data, often have existing damage to their blood vessels.Based on early studies, scientists theorize the virus may be causing more damage to the vessel through inflammation and clotting, or outright attacking the blood vessels themselves.On top of that, hypertension is common: “Almost half of all adults in the United States have hypertension,” Dr. Olulade said. “45 percent.”Patients with cardiac disease, like coronary heart disease and congestive heart failure, have existing damage to their heart.Early research shows the coronavirus can cause inflammation of the heart muscle. It might also damage the heart indirectly, as the fight with the immune system in the lungs lowers oxygen levels in the blood.“If your heart isn’t pumping enough oxygen out to the blood, that amplifies the risk and the threat of dying from COVID,” Dr. Olulade said.Patients with dementia, the fourth most common condition on the list, already have an elevated risk of dying from pneumonia, one of the calling cards of a severe COVID-19 infection. People with diabetes also have a risk of pneumonia. In fact, the risk is so high, the CDC recommends patients with diabetes get a pneumonia vaccination.For individuals with chronic kidney disease, scientists aren’t yet sure if the virus attacks the kidneys directly or the kidneys get hit with collateral damage from other body system failures.Regardless of the underlying condition, Dr. Olulade said taking steps to treat and keep it under control can greatly reduce your risk from the coronavirus.Individuals with mild or controlled asthma, for example, are not considered to be at higher risk of severe illness, she said.San Diego County’s list does not include two underlying conditions considered high risk by the Centers for Disease Control and Prevention: cancer and sickle cell disease.That might be because the 626 deaths are a small sample size, Dr. Olulade said. 3525

SAN DIEGO (KGTV) — The San Diego Council is expected to vote Monday on a controversial proposal by a developer to build a large office park on land surrounded on three sides by the Del Mar Mesa Preserve. Residents who live nearby have been fighting the project and hope to convince the councilmembers to block it.The project, called "The Preserve at Torrey Highlands," would go on a piece of land south of Sr-56 at Camino Del Sur. Locals call the property "The Notch" and say it's a mystery why the 11-acre parcel was left out of protected zone when voters approved the Preserve in 1996.The best explanation, several residents told 10News, is that the land was owned by the Catholic Church, which planned to build on the property. The Church project was approved but never built and the Church sold the land in 2015.A spokesperson for the developer, Cisterra, told 10News that the land was always meant for development and that an office park is much-needed in the area: "The Preserve at Torrey Highlands will help grow the innovation economy by creating a place for nearly 2,000 high-quality, high-paying jobs."Opponents say voters intended any development on the land to be low-rise and fit the character of the neighborhood. 1235

SAN DIEGO (KGTV) -- The San Diego City Council Tuesday voted unanimously in favor of adding movable tiny homes to the list of options on how to offer more affordable housing to citizens.Tiny houses are similar to granny flats, but smaller. Tiny houses come in a variety of shapes and sizes and are equipped with the basics for living, sleeping, and cooking. They range in size from 150 square feet to 400 square feet and cost between ,000 and 0,000.Tiny homes can help create an affordable option for low-income residents that doesn’t require a taxpayer subsidy.City officials said, “A significant portion of households in San Diego can afford a movable tiny house as an Accessory Dwelling Unit (ADU). The average cost of rent for a tiny home is 0 a month. A property owner would recover their initial investment in eight years. After that, the rent from the tiny house could help cover their mortgage and other expenses.”Currently, the city allows homeowners to build accessory dwelling units on their properties. With Tuesday’s approval, homeowners can add tiny homes to their properties.“Moveable tiny homes are a great option that naturally increases affordable housing at no cost to taxpayers. It’s a win for the homeowner, it’s a win for the renter, and it’s a win for the taxpayer,” said San Diego City Councilman Scott Sherman. “I appreciate my colleagues support for this important housing reform. We must continue pushing for common sense solutions that result in naturally occurring affordable housing.”Sherman has been working to approve the ordinance since 2018, the city said. 1607
