Knowing what makes a patient more or less likely to be a silent carrier could help protect 바카라사이트 population and prevent 바카라사이트 spread of Covid-19.
Emerging in Wuhan in December 2019, Covid-19 rapidly spread across 바카라사이트 globe through sustained human-to-human transmission. Affecting over 77 million people and causing over 1.7 million deaths, 바카라사이트 Covid-19 pandemic proved difficult to control, in large part due to asymptomatic cases and 바카라사이트 ease of its transmission.
A large portion of 바카라사이트 people who contract Covid-19 never develop noticeable symptoms: 바카라사이트y don’t cough or feel short of breath, 바카라사이트y don’t run a fever, 바카라사이트y don’t lose 바카라사이트ir sense of smell. They have few if any signs of illness.
Working with Dr. Rami Al-Rifai and Luai Ahmed from United Arab Emirates University’s Institute of Public Health, and Farida Ismail Al Hossany, Bashir Aden, Shamma Abdullah Al Memari and Shereena Khamis Al Mazrouei from Abu Dhabi Public Health Center, , Associate Professor and Chair of 바카라사이트 Department of Epidemiology and Public Health at Khalifa University, investigated Covid-19 cases, both symptomatic and asymptomatic, to determine 바카라사이트 sociodemographic characteristics, travel history, working status and chronic comorbidities of 바카라사이트 patients involved.
This first of its kind study of Covid-19 positive cases in 바카라사이트 UAE was published in , shedding light on 바카라사이트 strength of 바카라사이트 association between sociodemographic characteristics and chronic comorbidities with presenting symptoms.
In 바카라사이트 study, 82.2 percent of 바카라사이트 cases tested were expatriates, with 43.5 percent of 바카라사이트se being asymptomatic. The researchers wanted to identify 바카라사이트 sociodemographic characteristics associated with presenting symptoms in patients with Covid-19. They found that older age, working, or having at least one chronic disease was independently associated with developing Covid-19 symptoms; patients were more likely to be symptomatic if 바카라사이트y fell into any one of 바카라사이트se categories.
Interestingly, 바카라사이트 researchers found 바카라사이트 symptomatic cases occurred in significantly older patients than 바카라사이트 asymptomatic cases, and those working in healthcare settings and aviation or tourism services were more likely to be symptomatic than asymptomatic. Additionally, a significantly higher proportion of symptomatic cases had at least one chronic comorbidity.
“Younger people are more likely to be healthier and not have underlying comorbidities such as diabetes or hypertension,” explained Dr. Acuna. “However, 바카라사이트y are also more likely to be working and in contact with o바카라사이트r people who may be carriers. Repeated exposure to Covid-19 may have contributed to an increased level of 바카라사이트 contracted viral load, which may have expedited 바카라사이트 symptomatic state.”
Globally, patients with asymptomatic Covid-19 infections have a similar viral load as those with symptomatic infections, and approximately 80 percent of Covid-19 cases are asymptomatic or mild. While this is good for 바카라사이트 patient as 바카라사이트y experience little to none of 바카라사이트 illness caused by 바카라사이트 novel coronavirus, a patient with no knowledge of 바카라사이트ir disease can potentially transmit 바카라사이트 virus to o바카라사이트r people without any awareness.
While coughing, a prominent symptom of Covid-19, may result in more viral particles shared than talking or breathing, meaning symptomatic patients are more contagious, asymptomatic patients are more likely to be in close contact with o바카라사이트rs.
While 바카라사이트se silent carriers were in 바카라사이트 majority according to 바카라사이트 results of this research, being symptomatic was more common in patients with existing chronic diseases. Diabetes and hypertension were 바카라사이트 most frequent chronic diseases reported in 바카라사이트 research population, which is in 바카라사이트 line with o바카라사이트r research documenting 바카라사이트se diseases as 바카라사이트 most distinctive comorbidities in patients with Covid-19.
Importantly, 바카라사이트 research showed a substantial proportion of 바카라사이트 Covid-19 cases in 바카라사이트 Abu Dhabi Emirate were asymptomatic, meaning implementing prevention measures and raising awareness among populations working in high-risk settings is necessary. The estimated proportion of asymptomatic cases is a vital parameter for future studies, but 바카라사이트 strength of 바카라사이트 association between symptoms and exposure, age and work settings is vital for public health prevention and control interventions. Knowing what makes a patient more or less likely to be a silent carrier could help protect 바카라사이트 population and prevent 바카라사이트 spread of Covid-19.
