Long COVID affects 23% of positive cases, causing symptoms in ‘long haulers’ that may last for months

A new USC study found that 23% of people infected with COVID will be “long-term”, and found predictors of who could cause symptoms in some cases that could last months.

The study, which appeared in it Scientific Reportis unique because it has pre-existing symptoms such as fatigue and sneezing that are common to certain conditions and can be mistaken for COVID symptoms.

“Long COVID is a major public health concern. Twenty-three percent is very high, and can translate to millions of people,” said lead author Qiao Wu, a doctoral candidate at the USC School of Gerontology. Leonard Davis. “More knowledge about its prevalence, persistent symptoms and dangers can help health professionals dedicate resources and services to help long-term residents get back to their normal lives. “

The study found that obesity and hair loss during infection are predictors of long-term COVID, but other underlying conditions – such as diabetes or smoking status – have no way of detecting chronic symptoms.

Long COVID: Symptoms last 12 weeks or more

While SARS-CoV-2 is usually a contagious disease that lasts about three weeks, some people with COVID have symptoms that last for months or more. The World Health Organization defines long-term COVID as a symptom of more than 12 weeks or more, a term used by the study authors. Long-term COVID proliferation rates range from 10% to 90% due to improved research criteria and differences in drawing drawing.

For example, some studies have focused on hospitalized patients, which has provided limited insight into long-term COVID in the general population.

USC researchers used an Internet source national surveyThe Coronavirus Awareness Survey in the United States, conducted by the Center for Economic and Social Research (CESR) at the USC Dornsife College of Letters, Arts and Sciences – with an estimated 8,000 respondents from across the country.

From March 2020 to March 2021, researchers invited participants to answer weekly questions about COVID. Their latest sample included 308 infected people, who were not hospitalized who were interviewed a month ago, almost the time of infection and 12 weeks later.

Who will get long COVID? ‘Long ones’ describe the signs

After comparing the previous symptoms, nearly 23% of the participants reported that they had new symptoms during an infection that lasted more than 12 weeks, fulfilling the purpose of the long-term COVID study.

The first, most common symptoms of chronic coronary heart disease in COVID patients are:

  • Headache (22%).
  • Nasal congestion or nasal congestion (19%).
  • Dissatisfaction (18%).
  • Fatigue (17%).
  • Zawo (13%).

In addition, the researchers found that people were more likely to experience long-term COVID if, at the time of infection, they were:

  • They were overweight
  • Experience hair loss
  • Headache experience
  • He suffered from a sore throat

Suddenly, long-term COVID incidence among people with breast cancer decreased. There is insufficient evidence related to the risk of long-term COVID to pre-existing medical conditions such as diabetes or asthma, or age, gender, ethnicity, education or current smoking status.

“The significant association between long-term COVID and obesity is consistent with previous studies,” said Professor Eileen Crimmins, anthropologist at USC School Leonard Davis. “We differentiate some of the existing studies in that we do not find a link between long COVID and any social factors.”
