As COVID-19 cases spike across the country, public health experts, doctors and everyday people are constantly checking the spread of the virus in their communities.There are several tools available that give a variety of information regarding case levels. Some trackers provide the number of cases over a 100-day period, while others compare the number of positive tests to the total number of tests.The information can be overwhelming, especially for those who are not health experts. What information is useful, and how should the general public use it to make decisions about their everyday life?Health experts say any tool will help provide context to the situation, as long as the information comes from a legitimate source, like a state health website or reputable institution like Johns Hopkins University.But to make things easier to understand, experts suggest using just one tool in order to get information."If you're traveling somewhere, you want to be able to compare your risk at home versus your risk on the trip," said Dr. John Hammer, the chief of medicine at Rose Medical Center. "It's nice to have a tool that's used in both places to measure that."Using just one source makes it easier to understand the situation, even if the numbers vary from tool to tool. 1286

An isolated Amazon tribe with no known contact with the outside world has been spotted by a drone flying over the Brazilian jungle, according to the country's National Indian Foundation.Footage released this week shows several people walking through a wide clearing made in a patch of dense jungle in the Javary River valley, near the border with Peru.One of the figures is carrying a spear or pole of some kind, while four or five others stand near what look like thatched structures.None of the people spotted by the drone appear to notice their observer, which is flying high above the trees surrounding them. 620

Anyone who plans to travel internationally should get tested for COVID-19 before and after their trip, according to new Centers for Disease Control and Prevention (CDC) recommendations.In addition, the CDC says anyone returning from international travel should isolate for at least seven days — even if they test negative for COVID-19 upon their return.Planning aheadIn the new guidance published to its website, the CDC recommends travelers plan ahead several weeks before travel. The CDC says to avoid high-risk activities like large social gatherings (parties, weddings, funerals, sporting events), indoor recreation (bars, restaurants, fitness centers) and taking public transportation for at least two weeks.As the travel date approaches, the CDC recommends receiving a test between one and three days before boarding an international flight — but also to make sure test results are available before the flight departs. If the test results aren't back in time, the CDC recommends delaying travel.The CDC stresses that anyone who tests positive for COVID-19 should not travel — anyone who tests positive should immediately isolate and follow public health recommendations.The CDC also says that anyone who tests negative should still wear a mask, maintain 6 feet of social distance and wash hands frequently while traveling."A negative test does not mean that you were not exposed or that you will not develop COVID-19," the CDC says on its website.Finally, travelers should carry a copy of their test results with them — officials in other countries may ask to see them.Upon ReturnUpon return to the U.S., travelers should get another COVID-19 test within three to five days upon return. Even if that test comes back negative, the CDC urges a full week of self-isolation."You may have been exposed to COVID-19 on your travels. You may feel well and not have any symptoms, but you can be contagious without symptoms and spread the virus to others. You and your travel companions (including children) pose a risk to your family, friends, and community for 14 days after you were exposed to the virus," the CDC writes on its website.Anyone who chooses not to get tested upon their return to the U.S. should stay home for 14 days.Places where it's safe to travelThe CDC's website also includes risk assessment maps to help travelers determine where COVID-19 is spreading. As of Wednesday morning, nearly every country around the world was listed as a Level 4 risk — the highest level listed by the CDC.Click here to see the CDC's risk assessment map. 2559

APATUL VALLEY (CNS) - Firefighters battling the Valley Fire in rural eastern San Diego County worked to take advantage of lighter winds and higher humidity this morning in an attempt to increase containment of the blaze.The fire, southeast of Alpine, has burned 17,665 acres, destroyed 30 residences and 31 outbuildings, damaged 11 other structures, injured three firefighters and was 79% contained.At noon Friday, Cal Fire announced that all evacuations and road closures necessitated by the conflagration, dubbed the Valley Fire, had been lifted.However, Cleveland National Forest remained closed to the public until further notice ``to protect natural resources and provide for the safety of the public and firefighters,'' Cal Fire advised.``This closure will stay in place until conditions improve and we are confident that national forest visitors can recreate safely,'' according to the state agency.The blaze erupted for unknown reasons early Sept. 5 off Spirit Trail and Carveacre Road and spread rapidly through tinder-dry vegetation amid sweltering heat and high winds, Cal Fire officials said.Cal Fire cautioned those returning to the fire-ravaged area Friday to ``use extreme caution around trees, power poles and other tall objects or structures that may have been weakened'' by the blaze.The San Diego County Sheriff's Department will increased its patrols in the area to ensure public safety and prevent looting, according to Cal Fire.Officials advised that motorists in the area may face traffic disruptions due to the continued presence of firefighters, law enforcement personnel and utility workers still working there.Non-residents were asked to avoid locales in and around the burn zone if possible.About 140 San Diego Gas & Electric customers in Alpine, Barrett Lake, Dehesa, Lyons Valley and Rancho Palo Verde were without power. Electricity was restore to many customers on Friday and the rest were expected to be back online by Tuesday afternoon, the utility said.Due to smoke drifting over much of the San Diego region, the county Pollution Control District advised that the air quality may be unhealthy in some local communities and advised people to limit outdoor activities until conditions improve.Gov. Gavin Newsom declared a state of emergency for San Diego County Sunday due to the Valley Fire, a move intended to free up federal relief funds.County officials encouraged people who have lost their homes or other property to the wildfire to call for assistance at 858-715-2200 or email valleyfirerecovery.@sdcounty@ca.gov.Additionally, a county assistance center for victims of the blaze will be in operation at Rancho San Diego Library, 11555 Via Rancho San Diego, on Saturdays and Sundays from 10 a.m. to 6 p.m. and Mondays from 11 a.m. to 7 p.m. until further notice.Those who would like to help victims of the fire can make donations to a disaster-relief fund implemented by the San Diego Foundation, which can be accessed online at sdcountyrecovery.com. 3002
