SAN DIEGO (KGTV) -- For some people who catch the coronavirus, their symptoms can last for months. Researchers are calling these patients who now test negative but still experience symptoms "long haulers." Doctors are calling the long hauler problem a big mystery.It's a new phenomenon of a new virus, stumping even the brightest researchers and doctors."I have to tell him, I don't know," Dr. Zehui Tan with Sharp Rees Stealy Rancho Bernardo said.Dr. Tan is treating an otherwise very healthy 24-year-old man who tested positive for COVID-19 in September. She says after he quarantined for 14 days, most of his symptoms went away. He retook the test, and it came back negative. But the good news was short-lived. A month later, he ended up in the ER once again."His blood test is normal, chest is fine, but they found an abnormality in the EKG -- an inflammation of the heart. It can be a complication after COVID," Dr. Tan said.Researchers believe about 10% of COVID-19 patients see a relapse in symptoms. These "long haulers" now test negative for COVID but still experience symptoms that include coughing, fatigue, body aches, shortness of breath, loss of taste and smell, and brain fog."Almost three months after the COVID infection, he's still not feeling right," Dr. Tan said.Researchers say there does not seem to be a consistent reason or type of patient who becomes long-haulers."We see people die long from COVID, and I have a 92-year-old just fully recovered, so you just never know what's going to happen in your body once you get this COVID," Dr. Tan said.So it could be a long road ahead until her patient feels like himself again."We don't know," Dr. Tan said. "The only thing we can give is offer lots of support, treat them symptomatically, and then just watch and wait."Experts say patients who had bad respiratory issues may develop permanent lung damage. However, those who lost their sense of taste and smell will likely get those senses back. 1973

SAN DIEGO (KGTV) — For more than three hours, two women were trapped inside a downtown San Diego elevator.Fire crews were called to the Copley Symphony Hall at about 7:30 p.m. Wednesday after the elevator stopped as it took the women to the 34th floor.A Battalion Chief said the women felt a jolt and the elevator's lights flicker before it came to a stop.Rescuers were able to reach the women at about 11 p.m., more than three hours later. Until then, the women Facetimed a friend to stay calm, but a friend was worried they would run out of air or suffer from heat related injuries."Once I learned that they pried the doors open because it was so hot in there, what else could I do but just wait?" Kalani Creutzberg said. "It turned into a waiting game. And I'm just very very fortunate that there's a happy ending to this."Both women were taken to a nearby hospital to be checked out. While they were shaken up and nervous, neither appeared to have any serious injuries. 982

SAN DIEGO (KGTV) — Early data suggests the coronavirus vaccine candidates from both Pfizer and Moderna are safe and effective, but some patients may experience side effects that can feel intense but resolve quickly.More than 37,000 people have taken either the Pfizer or the Moderna vaccine in a Phase 3 trial. Both vaccines require two doses, and side effects were more common after the second dose.Pfizer reported 3.8% of the recipients felt fatigue and 2% experienced headache, based on preliminary data from its Phase 3 trial. These symptoms are classified as Grade 3 or “severe” adverse events because they can interfere with daily activity.Moderna reported more Grade 3 side effects. There was fatigue in 9.7% of recipients, muscle pain in 8.9%, joint pain in 5.2%, headache in 4.5%, pain in 4.1%, and redness at the injection site in 2%.Neither company reported side effects that affected less than 2% of participants in their press releases but more detailed data will be released.Dr. Peter Chin-Hong, an infectious disease specialist at UC San Francisco, said the symptoms typically appear in the first few hours after vaccination and resolve within 24 to 36 hours.“The most troublesome of them for people has been low grade temperatures, but they go away in many cases without even using anti-inflammatories” like ibuprofen, he said.Experts say the vaccines appear to have a higher rate of Grade 3 side effects than the typical flu vaccine, even high-dose flu vaccines, but they say there’s no reason to worry about so-called reactogenic symptoms like muscle and joint pain.“Usually if it hurts that's a positive sign. That's your immune system actually responding to the immunization so that it's going to be able to fight off the virus in the future,” said Dr. Shane Crotty, a virologist at the La Jolla Institute for Immunology.Both leading COVID-19 vaccines rely on the same platform: messenger RNA. This technique has never been used in an approved vaccine before.There is no evidence yet of any long-term side effects, but they can’t be ruled out either. The fragility of mRNA makes it unlikely to linger in the body but any vaccine could theoretically cause disruptions in the immune system, experts said.The FDA required vaccine makers to follow vaccine recipients for a median of two months after the second dose before seeking approval to detect longer term side effects.“I think that's a pretty good window to see a bad side effect like Guillain-Barré,” said Dr. Christian Ramers of Family Health Centers of San Diego. “It really should show up within those two months after the second shot.”Guillain-Barré Syndrome can cause paralysis and some flu vaccines have been associated with increased rates of it. But the increased rates are still extremely rare: an extra 1 to 2 cases for every million doses, according to the CDC.Dr. Ramers said the long-term consequences of contracting COVID-19 are much more concerning.“This is not a virus that you want to get,” he said. “There are unpredictable effects. There are healthy young people developing clots and strokes.”A study on COVID-19 patients in Michigan found that two months after hospitalization, 32.5% had a lingering cough or difficulty breathing and 11% reported new or worsening trouble caring for themselves.Both the FDA and the CDC are taking extra steps to monitor people who get the vaccine early for any side effects. The CDC plans to monitor recipient’s health via text message for several weeks, including one or more texts per day during the first week. 3548

SAN DIEGO (KGTV) - Driving back from a call in Jamul, two HVAC technicians act quickly to help a driver trapped in a smoking car. The accident happened on Campo Road."It looked like the truck got t-boned by a car and flipped on its side," one of the technicians told 10News.For Kyle Hester and Anthony Ramirez, it was a day they will never forget."Working and something crazy happened, you'll never forget it it’ll always be a story to tell," Ramirez said.Dashboard cameras installed in their work truck weeks ago caught the entire incident on camera."It all happened in a matter of seconds," said Ramirez.Hester and Ramirez pulled up to the crash before firefighters and paramedics were there.
