Three negatives and a positive: Problems with coronavirus tests in China


first_imgTopics : Finally, at least, he had an explanation for why he felt so terrible. “I felt like I was dying. You can’t imagine how it feels.”His case is not unique. Similar instances in China and elsewhere have compounded concern over the accuracy of coronavirus testing, even as authorities push for testing as key to handling the crisis.Unreliable testing could undermine strategies not just for stopping the virus but for opening up locked-down economies, as pressure grows on governments around the world to ease restrictions.More than 2.5 million people have been infected with the coronavirus globally and about 177,000 have died, according to a Reuters tally.Wuhan, where the new coronavirus emerged late last year, has recorded 50,333 cases and 3,869 deaths as of April 21, accounting for the majority of China’s cases.Nucleic acid testing, on samples swabbed from the back of a patient’s throat or respiratory tract, for the virus’ genome, is the main way cases are detected.The test is not easy to administer and, experts say, and mistakes do happen, such as if too small a sample is taken or if the swab misses a virus-hit spot.”The limitations of these tests need to be recognized, and the need to run regular tests if we want assurance that someone is truly negative, and that they remain so over a period of time,” said Andrew Preston, a lecturer in microbial pathogenesis at the University of Bath.Testing times There is little consensus on what proportion of nucleic acid tests yield false negatives.A survey by Chinese doctors in February looking at samples from 213 patients suggested a false-negative rate of about 30%.Media has also reported cases of people testing negative repeatedly before finally getting a positive result.In February, the People’s Daily newspaper reported on a woman who had fallen ill with pneumonia but tested negative for the coronavirus four times. A fifth test was positive.Wuhan authorities have started testing residents for antibodies. China is conducting an epidemiological survey in nine regions in an effort to determine the full extent of asymptomatic infections and immunity levels.He said he first got tested on March 1 when his chest congestion worsened though he had no fever or cough.X-rays showed his lungs had white blotches, similar to those found in coronavirus patients, but his nucleic acid test was not positive so a hospital declined to admit him.As a precaution, a committee that manages his housing compound put him in quarantine for 14 days.Later, two more hospital tests came back negative so he turned to traditional Chinese medicine and other drugs.Finally, on March 28, he took a fourth nucleic acid test, which was again negative, but he was also tested for antibodies and got confirmation.”I told my story to a doctor and he said ‘you’re so lucky you didn’t die’,” he said in his apartment, where boxes of various medicines were scattered about.His wife, who he lives alone with, has shown no coronavirus symptoms though she has not been tested.He said he believed he was immune and not infectious, though he’s taking no chances and wears an N95 mask and a face shield when going out.”If there’s any possibility that I’ll infect others, I’ll harm them,” he said. “That’s why I’m taking these precautions.” Still, he did not challenge the three negative tests at the time. After all, his wife did not fall sick.But he could not shake off the nagging suspicion that he had the coronavirus and in late March went to a hospital in Wuhan for more tests, including one for antibodies.This time he tested positive.”I didn’t expect it,” the 52-year-old vegetable seller said as he showed Reuters a copy of his test results – positive for antibodies showing exposure to the coronavirus.center_img Trader He Ximing in the Chinese city of Wuhan says he has no idea how or where he caught the coronavirus or why repeated nucleic acid tests showed he didn’t have it.He was not a coronavirus patient, doctors told him, even though he had been having difficulty breathing with what he described as smothering chest congestion from early February.But his condition worried the authorities enough to get him sent to a quarantine center.last_img read more


Pennsylvania comparte la actualización del panel de datos de monitoreo de alerta temprana de COVID-19, casos entre empresas, grupos de edad


first_img Español,  Press Release,  Public Health El Gobernador Tom Wolf y la Secretaria de Salud, Dra. Rachel Levine, publicaron hoy una actualización de estado semanal que detalla los esfuerzos de mitigación del estado basados en el Panel de control del sistema de monitoreo de advertencia temprana de COVID-19, que compara el período de siete días del 7 al 13 de agosto con los siete días previos, del 31 de julio al 6 de agosto, junto con datos sobre casos que informaron haber visitado una empresa entre posibles exposiciones y datos específicos por edad para personas de 19 a 24 años.El panel está diseñado para proporcionar signos tempranos de advertencia sobre los factores que afectan las medidas de mitigación del estado. La información disponible en el panel incluye las diferencias de casos semana a semana, las tasas de incidencia, el porcentaje de pruebas positivas y las tasas de hospitalizaciones, el uso de respiradores y las visitas a las salas de emergencias vinculadas a la COVID-19.“Nuestro porcentaje de positividad disminuyó por tercera semana consecutiva, lo cual es un testimonio de que se están realizando las pruebas, y que las pruebas están ampliamente disponibles en todo el estado”, dijo el Gobernador Wolf. “Sin embargo, con el aumento de las pruebas se incrementa el número de casos. El virus aún está circulando y debemos seguir usando máscaras, practicando el distanciamiento social y evitando grandes reuniones para que los números sigan siendo bajos, lo que detendrá la propagación y permitirá más libertad”.A partir del jueves 13 de agosto, el estado ha visto un aumento de 5,530 casos en siete días. El aumento de los siete días previos fue de 5,030, lo que indica un aumento de 500 casos en todo el estado durante la semana pasada.El porcentaje de positividad en todo el estado bajó al 4.0% respecto del 4.1% de la semana anterior. Los condados con un porcentaje de positividad preocupante incluyen Fayette (10.4%), Armstrong (8.9%), Cameron (8.7%), Huntingdon (7.1%), Dauphin (6.5%), Northumberland (6.4%), Mercer (6.3%), Erie (5.9%), Crawford (5.8%), Forest (5.8%), York (5.6%), Indiana (5.5%), Franklin (5.4%), Lawrence (5.3%) y Berks (5.0%). Cada uno de estos condados está siendo observado a medida que el estado continúa la supervisión de toda la información disponible.El Departamento de Salud ahora está proporcionando datos sobre la cantidad de personas que respondieron a los investigadores de casos que pasaron tiempo en establecimientos comerciales (restaurantes, bares, gimnasio/centro de fitness, salón/barbería) y en reuniones masivas 14 días antes del inicio de síntomas.De los 24,468 casos positivos reportados entre el 13 de julio y el 11 de agosto, menos de la mitad de las personas respondieron a la pregunta de si pasaron tiempo en un establecimiento comercial. De aquellos que dieron una respuesta, el 13 por ciento, o 1,499 respondieron que sí, visitaron un establecimiento comercial 14 días antes de la aparición de los síntomas:El 47 por ciento de los que dijeron que sí informaron haber ido a un restaurante;El 24 por ciento de los que dijeron que sí informaron haber ido a un bar;El 19 por ciento de los que dijeron que sí informaron haber ido a algún otro establecimiento comercial;El 10 por ciento de los que dijeron que sí informaron haber ido a un gimnasio/centro de fitness; yEl 9 por ciento de los que dijeron que sí informaron haber ido a un salón/barbería.De los 24,468 casos, el 52 por ciento respondió a la pregunta de si asistieron a una reunión masiva u otro evento importante. Del 52 por ciento, casi el 12 por ciento (1,648) respondió afirmativamente si asistieron a una reunión masiva u otro evento importante 14 días antes de la aparición de los síntomas.Las notas del investigador de casos incluyeron menciones frecuentes de visitas a bares y restaurantes entre los casos positivos. Para comprender mejor esta tendencia emergente, el 13 de julio, los rastreadores de contactos comenzaron a hacer preguntas más específicas sobre los tipos de negocios visitados y si las personas asistieron a una reunión masiva, definida como más de 250 personas al aire libre o más de 25 en el interior.Los números anteriores destacan los entornos comerciales y las reuniones masivas como posibles sitios de transmisión. Aproximadamente a la mitad de los encuestados se les preguntó sobre los tipos de negocios que visitaron o si asistieron a una reunión masiva respondiendo a la pregunta, el departamento les recuerda a los residentes de Pennsylvania que es esencial que las personas contesten el teléfono cuando los investigadores de casos llamen y que brinden información completa a estos profesionales clínicos.También hoy, el Departamento de Salud actualizó sus recomendaciones de viaje, anunciadas originalmente el 2 de julio, para eliminar Nebraska, North Carolina, Utah y Wisconsin de la lista de estados recomendados para viajeros nacionales que regresan a cuarentena durante 14 días al regresar a Pennsylvania.Es importante que las personas comprendan que esta recomendación está en vigor para prevenir la propagación de COVID-19 en Pennsylvania. Un número preocupante de casos recientes se ha relacionado con viajes, y si las personas van a viajar, necesitamos que tomen medidas para protegerse a sí mismas, a sus seres queridos y a su comunidad, y eso implica la cuarentena.Además, el departamento ha analizado el cambio porcentual en los casos entre jóvenes de 19 a 24 años desde abril hasta el 14 de julio, en comparación con abril hasta el 14 de agosto después de que se implementaron los esfuerzos de mitigación más recientes:El porcentaje de casos entre los jóvenes de 19 a 24 años en el SW ha disminuido en un 12 por ciento (24 por ciento al 14 de julio a 12 por ciento al 14 de agosto);El porcentaje de casos entre los jóvenes de 19 a 24 años en el NC ha disminuido un cinco por ciento (14 por ciento al 14 de julio a 8 por ciento al 14 de agosto);El porcentaje de casos entre los jóvenes de 19 a 24 años en el NW ha disminuido en un tres por ciento (12 por ciento al 14 de julio a 9 por ciento al 14 de agosto);El porcentaje de casos entre los jóvenes de 19 a 24 años en el SC ha disminuido en un por ciento (13 por ciento al 14 de julio a 12 por ciento al 14 de agosto);El porcentaje de casos entre los jóvenes de 19 a 24 años en el SE, se mantuvo igual (17 por ciento al 14 de julio a 17 por ciento al 14 de agosto); yEl porcentaje de casos entre los jóvenes de 19 a 24 años en el NE se mantuvo igual (17 por ciento al 14 de julio a 17 por ciento al 14 de agosto).Las disminuciones en este grupo de edad, donde vimos aumentos significativos de casos antes de los esfuerzos de mitigación del 15 de julio, indican que las acciones están funcionando, pero deben continuar viendo disminuciones adicionales en todo el estado.El Gobernador Wolf sigue dando prioridad a la salud y la seguridad de todos los residentes de Pennsylvania a través de la pandemia de COVID-19. Los residentes de Pennsylvania deben continuar tomando medidas para prevenir la propagación del COVID-19, independientemente del condado en el que vivan. Esto incluye usar una máscara o cubrirse la cara en cualquier momento que estén en público. Se ha demostrado que COVID-19 se propaga fácilmente en el aire y los portadores contagiosos pueden ser asintomáticos.View this information in English.

DraftKings Lineup Picks: MLB DFS strategy, sleepers for Tuesday, April 23


first_imgLast night’s lineup managed to cash for us in our tournament — thanks in part to a late pivot to the lightly owned David Peralta — and even modest winnings are still winnings, so we’re hoping to keep things going with Tuesday’s DraftKings lineup picks. The pitching options tonight aren’t the greatest, so you’ll have to take some chances with your choices there, but there are plenty of decent hitter sleepers to help round out a stars-and-scrubs strategy. Yesterday we went with two three-man stacks in our offense, but with more games (and the Nationals not facing a lefty), we’re using a slightly more varied approach. We still have two mini-stacks, but on packed main slates like tonight’s 13-gamer, it never feels like you have pieces of enough games. Watch ChangeUp, a new MLB live whip-around show on DAZNOur pitchers are from the top options, but slow and steady might win the race tonight, even in tournaments. You can make a strong case for Domingo German being close to a must-have, but he’ll likely have high ownership even at a $9,000 price tag, so fading him could really pay off if he struggles. As it stands, we feel good about one of our two pitchers, and that’s probably going to be the case for many.MORE: Tuesday’s SP rankings | DFS lineup BuilderDraftKings Lineup Picks: Tuesday, April 23Starting Pitcher: Trevor Williams, Pirates vs. Diamondbacks ($8,300). You’d like a higher K-rate than 6.3, but Williams has been consistently solid this year, registering a quality start in all four outings. The matchups have been mostly favorable (Reds twice, Nationals, Tigers), but the D-backs aren’t exactly a worrisome opponent. Arizona ranks 18th with a league-average 100 wRC+ against righties this year, and perhaps even more important, it strikes out at a 24.1-percent clip against righties, which is slightly above league average. Williams might get an extra K or two because of the matchup, and he’s always been a better pitcher in Pittsburgh (3.30 ERA) than on the road (4.05)Starting Pitcher: Trent Thornton, Blue Jays vs. Giants ($7,000). Chances are, you’re going to be taking some risk with your second pitcher on DK tonight, and Thornton fits that profile. He’s yet to go past the sixth inning this year, and his ground-ball rate of 29.4 percent leaves a lot to be desired. That said, there are plusses, starting with the matchup (San Francisco is 29th in wRC+ vs. righties) and Thornton’s K-rate (10.3). This is one of those boom-or-bust matchups that you’d probably only use in tournaments, but we’ll take our chances given the other options and Thornton’s price tag. Catcher: Mike Zunino, Rays vs. Royals ($3,300).  Normally, we don’t like using someone like Zunino the day after he hit a homer, as it’s unlikely he does it again. But the big backstop tends to hit them in bunches, and fly-ball pitcher Homer Bailey tends to give them up at the same rate, so we’ll hope lightning can strike twice here. Ultimately, we’re just punting the position, so if you’re going to go the cheap route, you might as well go with someone who has legit multi-HR upside. First Base: Yonder Alonso, White Sox @ Orioles ($4,100). Camden Yards is a hitters paradise, and Andrew Cashner has been especially friendly to lefthanded hitters since 2016 (.269/.351/.456). Alonso has had a slow start to his first season with the White Sox, but this is a good spot for a big game.Second Base: Kolten Wong, Cardinals vs. Brewers ($4,300). Lefties has always hit better against Zach Davies, getting on base at a .369 clip against him since the beginning of last season. Wong has had a run or RBI in seven of his past nine games, and he always has the potential to hit a homer and/or steal a base in the same game. Third Base: Yoan Moncada, White Sox @ Orioles ($4,900). Moncada scored twice last night, but with only one hit and no RBIs, he was mostly left out of the fun of a 12-run explosion. That won’t be the case tonight against Andrew Cashner. We’re all about getting lefthanded sticks in the lineup against Cashner, and Moncada hits better from that side of the plate (.645 SLG this year vs. RHPs, .454 for his career).Shortstop: Orlando Arcia, Brewers @ Cardinals ($3,200). We didn’t have the money to pay up for Trevor Story or Tim Anderson, so we ultimately decided to punt the position and pay way down for Arcia. The 24-year-old shortstop has shown a little more pop this year than last season’s dreadful campaign, but ultimately he’s once again disappointing. Given his and the Brewers’ matchup against inexperienced pitcher Daniel Ponce de Leon, we’re hoping he can get on base once or twice and be part of a run-scoring trip or two. Anything else is a bonus. Outfield: Christian Yelich, Brewers @ Cardinals ($5,800). Yelich has had two straight hitless games…so he’s due, right? Yes, we know about the home-road splits (.244/.295/.293 on the road this year), but we’re not getting carried away with a small sample. Last year Yelich hit .328/.399/.545 on the road, including .318/.483/.773 in six games at Busch Stadium. We’re not worried about him, especially against a righty making his 12th career major league appearance (fifth start).Outfield: Juan Soto, Nationals @ Rockies ($5,000). We want a piece of the Coors Field game, and we’re probably taking the most obvious one. While Soto is priced up, he’s only tied for the 10th highest-priced OF. Compare that to Anthony Rendon ($5,600), Nolan Arenado ($5,100), and Trevor Story ($5,200), who are not only more expensive but also the top-priced guys at their positions. Soto feels like a bargain considering he’s facing  Jeff Hoffman, who’s making his first start of the season. Last night we did well with “value Coors guys”, but tonight we’re taking the obvious high-priced bait. Outfield: Enrique Hernandez, Dodgers @ Cubs ($4,100). We kind of like Ian Desmond ($3,500) as a value Coors guy against lefty Patrick Corbin, but the extra $600 didn’t really allow us to upgrade too much anywhere else, so we’ll happily take Hernandez against lefty Jose Quintana. Hernandez is once again crushing southpaws (.500/.636./938), which is in line with his career splits (.273/.363/.505 vs. LHPs). He’s a no-brainer in these spots, even if he does generally hit worse on the road.last_img read more
