Is it coronavirus?The virus has evolved, what are the current symptoms to detect infection

Although movement between cities and countries seems normal and many of us have forgotten the fateful March 2020, The new coronavirus is still circulating around the world and the epidemic continues. Since its introduction, more than 770 million people have been diagnosed with COVID-19 and 6,957,216 have died, according to data reported to the World Health Organization. World Health Organization (WHO).

It’s obvious that the way Disease manifestations in people Changing. Doctors say they are finding it increasingly difficult to distinguish COVID-19 from allergies or the common cold, even as hospitalizations continue to rise. certainly, test They are an essential tool for detecting whether it is a virus.

Characteristic symptoms of coronavirus infection, such as dry cough or loss of feeling taste or smellThe frequency is now lower if one takes into account the increase in COVID-19 cases recorded in different countries since July last year.

Instead, doctors will consider The condition is mildmainly concentrated in the upper respiratory tract.

When asked, he said: “Today’s COVID-19 is increasingly difficult to distinguish from other respiratory diseases.” database Vice President of the Argentine Society of Infectious Diseases (SADI), Adrian Morales.

“They’re different from the typical symptoms we’ve seen before. It causes severe congestion, sometimes sneezing, and often a mild sore throat,” the doctor said. ” Eric EttingVice President of Emergency Medicine Operations Mount Sinai City Center New Yorkinside USA. A sore throat usually appears first, followed by congestion, he added.

In conversation database doctor Javier Farinaof Argentine Society of Infectious Diseases (SADI) “This change is due to the degree of immunity gained from previous infection or vaccine protection,” he explained.

inside U.K.Symptom study COVID-19 Zoe Data on self-reported symptoms were collected via a smartphone app. He documented the same trend.Their research results show sore throat Becomes more common after variant Omicron Become dominant by the end of 2021.

On the other hand, anosmia became less common and hospital admissions declined compared to summer and autumn 2021. Doctors now describe a clearer, more coherent pattern of symptoms.

“Almost everyone I see has very mild symptoms,” Eiting said of his urgent care patients, adding: “The only way we know it’s COVID-19 is because we happen to treat them Tested.”

doctor Grace McConcySome patients have commented that they have “a burning sensation that they’ve never had before, even in patients who have had strep infections in the past,” said the associate dean for clinical and translational research at Case Western Reserve University. “Once a blockage occurs, The throat seems to get better,” he said.

with congestionAccording to doctors, some patients experience symptoms such as headache, fatigue, muscle aches, fever, chills, or postnasal drip, which can lead to coughing, although coughing is not the main symptom.

Dan BaruchDirector, Center for Virology and Vaccine Research, Medical Center Boston Deaconess Beth IsraelMild symptoms observed by doctors were also attributed to immunity to the vaccine and previous infection.

“Overall, the severity of COVID-19 is much lower than it was a year ago and two years ago. It’s not because these variants are less robust. It’s because the immune response is stronger,” Baruch said.Symptoms can Appears 2 to 14 days after exposure to the virus.

In Argentina, people who can visit after detecting symptoms test in public hospital are those considered priority groups: People over 50 years old, pregnant women, and people with comorbidities such as diabetes, grade 2-3 obesity, cardiovascular disease, chronic kidney disease, chronic respiratory disease, chronic liver disease, etc.

Priority groups also include people living with HIV, people with intellectual disabilities, carriers of tumors or oncohematological diseases, pre- or post-transplant patients, carriers of autoimmune diseases or those receiving immunosuppression-immunomodulation or biologic therapy, and tuberculosis.

In addition, essential workers (staff or residents of long-term residential facilities, health service staff, or security personnel) and those living with high-risk individuals must also be tested.

one of the Reasons for the increase in COVID-19 cases This would be the entry of a more transmissible sublineage of the coronavirus into the country. It is often called Eris.The name of the World Health Organization is Omicron EG.5. Another reason for the increase in cases is that many people are no longer protected by the vaccine because they do not get booster shots.

Beyond the vaccine, it’s important to note that coronavirus is primarily spread through the air. If a person is infected (with or without symptoms), they can spread the virus by exhaling, coughing, sneezing, talking, shouting, or singing. Therefore, it is important to reduce the use of enclosed spaces or use permanent cross ventilation.

“Ventilation is key to avoiding outbreaks or super-spreading in enclosed spaces where many people share the air,” he stressed. database scientific Andrea Pineda Rojasresearcher at the Center for Oceanic and Atmospheric Research, depending on Conicet and School of Exact and Natural Sciences of the University of Buenos Airesand one of the organizers of the Ventilar del del event Argentina Ministry of Science, Technology and Innovation.
