MIAMI, Florida.- At the beginning of the coronavirus outbreak, there was a theory that the threat of contagion in the United States would be reduced as the northern hemisphere began to heat up as a result of spring and by the summer, the disease it produces -covid- 19- it will disappear. “When the weather warms up a bit, it miraculously disappears,” said President Donald Trump in one of his last campaign events in February. Just a month later, doctors and scientists warn that, although several studies have shown that The weather affects flu-like viruses, that doesn’t seem to be the case for covid-19. “It’s like a forest fire. It just spreads much more,” he added, comparing it to California forest fires that consume everything in its path. “There is no immunity” Previous coronavirus epidemics, such as the flu, have circulated for decades, which has allowed the population to develop immunity, he explained in a telephone interview. “When you have a pandemic like this, there is no basic immunity to prevent it. It’s something totally different,” he said. As a result, he cautioned that factors such as temperature should be ignored. “I think it is irrelevant at this stage,” he said. Reports confirm that coronavirus cases have now exceeded 430,000 worldwide, and show no signs of slowing down. More than 19,000 people have already died worldwide, most in China, Italy and Spain, and the death toll increased by more than 700 in the United States. Univision News spoke to half a dozen doctors and scientists who confirmed that we should not expect relief with rising temperatures. “The message is that we don’t know enough. We can’t underestimate this virus,” said Dr. Marcos Espinal, director of Infectious Diseases at the Pan American Health Organization (PAHO) in Washington, the The world’s oldest public health agency that is a regional partner in the Americas of the World Health Organization (WHO). Latin America Espinal noted an increasing number of confirmed cases of coronavirus in South America, with more than 100 deaths so far, a despite currently being at the end of the summer season. Panama reported 443 cases, although it has one of the smallest populations in the region and where temperatures this week were around 90ºF (32ºC). “Initially we all hoped that the heat and the tropical climate would stop the entry of the virus to our countries, “Dr. Xavier Saez-Llorens, a member of the technical committee that directs the response of the Panamanian government in a telephone interview on Tuesday, told Univisión Noticias.” However, the current evidence indicates that this is not the case … or really “This initial hope was false. The virus has really entered all of our countries with force,” he added. As a result, Panama entered a total quarantine as of Wednesday, “similar to Wuhan,” he said, referring to The Chinese city where the virus is believed to have originated and was cut off from the outside world for weeks. Worried Florida Governor. Cases were also increasing rapidly in the sunny Miami, the epicenter of the outbreak in Florida, where the temperature hovered around 80ºF on Tuesday. On Monday, Governor Ron DeSantis expressed concern about reports from people in New York, a heavily affected area, seeking refuge from the coronavirus outbreak In southern Florida, DeSantis announced Monday that it will require anyone on a flight from the New York City area to isolate themselves for 14 days upon arrival in Florida for the purpose of controlling the spread of the coronavirus.
The growing number of positive test results in Miami does not reflect what medical professionals see on the ground, according to a letter released Monday by 75 Miami emergency room doctors, nurses and physician assistant doctors. “The low number of Confirmed cases in published reports do not show the true number of people who have been infected by the virus in Miami, or anywhere else in the United States, “the doctors wrote. “It only reflects where we should do the testing,” they said. Experts say that instead of relying on weather factors, local health authorities should heed calls for more containment and mitigation measures, especially in big cities. “Cases generally occur in urban areas and places where much travel is done, such as coastal cities,” said José Szapocznik, a public health scientist at the University of Miami.
Evidence was also lacking in many places, not just in the United States, he added, pointing to Russia, which has reported just 495 cases and one death, or Nicaragua, with allegedly two cases. “The problem with statistics is that there is a lot of garbage. Yes the evidence is inadequate, we have no idea of the transmission, “he said.
“There is great concern about what will happen in the great megacities of Latin America,” said Gregory Glass, a professor at the University of Florida and a member of the Institute of Emerging Pathogens (EPI). “It is not about whether they are better or worse prepared. It is a great challenge to provide care in any city. Just take a look at Europe,” Glass told Univision News in a telephone interview from his home in Gainesville, Florida, that It was quarantined on Monday. The only possible positive point for Latin America, he said, was the age distribution in the region “which, in most countries, tends to favor young people.” Images of the pandemic: these Photographs describe the harshness of an unprecedented global crisis The flu season “No one can guarantee that it will not affect us,” agreed Alexandra Hill, foreign minister of El Salvador, who participated in the same panel.
Glass and the other experts said the key to understanding the impact of climate on covid-19 is to learn more about its behavior and how it is transmitted, as well as its ability to resist environmental conditions. Scientists say the virus is transmitted by droplets from the airways when an infected person coughs or sneezes. These droplets can fall directly into the mouth or nose of people who are near or onto solid objects, such as doorknobs and shopping carts, before passing indirectly to another person.
When the virus contaminates objects it falls on, studies of other epidemics show that warmer temperatures and wetter conditions could delay its spread due to increased exposure to the environment. “But if transmission occurs more through Close personal contact with families and crowds, so temperature and humidity in the environment probably won’t play a role, “Glass said. Flu and the Stations In temperate parts of the world, the flu tends to have a seasonal pattern with spikes during the winter, like other milder forms of coronavirus. “Cold, dry conditions seem to favor the flu virus,” said Baker, who studies the effects of climate change on viruses. On the other hand, in the warmer tropics, the flu season tends to extend throughout the year, with some spikes during the rainy season. Other forms of coronaviruses, such as severe acute respiratory syndrome or SARS, and MERS (Middle East respiratory syndrome) also appear to thrive in colder temperatures and drier climates. Preliminary evidence of one study out of 100 Chinese cities that had more than 400 cases revealed that the coronavirus was transmitted faster in places with cooler and drier weather conditions. Wuhan, the epicenter of the virus, generally has temperatures in the range of 40ºF (4.4ºC to 9.4ºC) during December and January. Another analysis of statistical data by two MIT scientists found that 90% of covid transmissions March 19-21 occurred in regions with temperatures below 17 ° C and low humidity. However, the authors told Univision News that the study was conducted at an early stage in the spread of the virus and that it was too early to draw certain conclusions.They noted that the role of warmer temperature in slowing the spread of the virus The virus “could only be observed, if at all, at much higher temperatures” that would not affect most cities in the United States and Europe. The authors also said that factors such as cultural norms, measures of social distancing, and Lack of evidence may have distorted the number of cases reported in some countries. Human behavior cannot be ruled out, either, because people often spend more time together indoors during the winter, Baker said. “There are multiple theories out there,” he said. “But the strongest evidence is that it all depends on the survival of the virus,” he said. Another factor was the size of the dose of virus needed to infect a potential victim. “Generally, there is a certain dose. In this case, we don’t know what the dose is,” Glass said. We won’t know until I’m done. Finding that out will take time. “We really won’t know until it is all over, in the later report,” he said. Meanwhile, quarantine and social distancing are the best defense against transmission. “We have to act with caution,” he said. “The bottom line is that the weather is not going to slow down the spread. Whoever trusts that is trying to cover the Sun with a finger,” Glass added. In photos: This is how you face the US coronavirus from coast to coast (photos)
