La doctora Kathleen Page, profesora asociada en la Escuela de Medicina de la Universidad Johns Hopkins, explica que existen dos tipos de pruebas para identificar si una persona tiene covid-19. La prueba PCR identifica al virus y sirve para conocer casos actuales, mientras que la prueba de serología se encarga de medir anticuerpos y sirve para conocer al total de la población que está o estuvo infectada.

Melissa Castro (L), head chef at Ccori, an organization that promotes socio-environmental gastronomy with support from the French companies Sodexo and Stop Hunger, and Adeli Yanos, president of "Virgen del Rosario" soup kitchen, train a group of women to prepare a dish using the peels, leaves, and stems of vegetables and fruits at the soup kitchen in Lurin, in southern Lima, on April 11, 2024. Peruvian Chef Palmiro Ocampo launched a crusade in 2018 to not waste food. To do this, he shares his recipes with dozens of mothers from soup kitchens in poor areas of Lima and has managed to optimize more than a ton of ingredients that normally ended up in the trash and have been turned into delicious dishes.

TO GO WITH AFP STORY BY YEMELI ORTEGA LUYANDO - A woman with obesity sits on the sidewalk in Mexico City on May 20, 2013. Obesity among Mexicans soared from 9.5% in 1988 to 32% in 2012 and if overweight is included, up to 70%. The Mexicans also contribute with 22,000 out of the 180,000 people who die annually in the world from conditions related to the intake of sweet drinks, a figure that doubles the 10,000 deaths caused by the organized crime in the country.

MIAMI, FLORIDA - JULY 10: A pile of food is seen after the owners of the Buya restaurant had to discard items from the restaurant's kitchen after having to close the establishment on July 10, 2020 in Miami, Florida. Jeff Grosser, a co-owner, said they have had to throw out about $8,000 worth of food and lay off 22 employees due to closure orders. He and other restaurant owners in Miami-Dade County say county Mayor Carlos Gimenez’s decision to close restaurant dining halls amid the surge in COVID-19 cases is unfair to them as other businesses stay open. They claim there is no clear evidence that closing them is part of a realistic plan that will effectively manage the current crisis in the spread of COVID and they should be able to stay open.

Guatemala's Attorney General, Consuelo Porras, attends a press conference at the Public Prosecutor's Office building in Guatemala City on May 7, 2024. Guatemala's President Bernardo Arevalo headed to Congress on May 6 to present legal reforms that would allow the removal of Attorney General Consuelo Porras, whom he accuses of plotting to oust him. Porras, who is under US and EU sanctions for corruption, was appointed by Arevalo's predecessor and led efforts to have the newcomer's election victory overturned. Her mandate runs until May 2026, and Arevalo cannot legally fire her without showing just cause under the current law. (Photo by Edwin BERCIAN / AFP) (Photo by EDWIN BERCIAN/AFP via Getty Images)
