On 23 Aug. 65 Assoc. Prof. Dr. Teera Woratanarat, Faculty of Medicine Chulalongkorn University Posted a message via Facebook, Thira Woratanarat stated that…
Yesterday, worldwide, 451,561 more people died, 1,205 more deaths, bringing the total to 601,329,157 people, total 6,473,267 deaths.
The top five with the most infections were Japan, South Korea, Russia, Taiwan and the United States.
Yesterday, the number of new infections had countries from Europe and Asia occupy seven of the top 10 and 15 of the world’s top 20.
The number of new infections every day in the world now. from Asia and Europe together accounted for 89.33 percent of the world’s population, while the number of deaths accounted for 72.86%.
…The epidemic situation of Thailand
From this morning’s Worldometer data, it was found that
Number of deaths yesterday The 12th highest in the world and 6th in Asia, although the Thai Ministry of Health has adjusted the reporting system from 1 May until the number of reports is greatly reduced.
…Update knowledge regarding the incubation period of COVID-19
Wu Y et al from China conducted a systematic review of the research. and meta-analysis About the average incubation period for COVID-19 classified by different species in the past
Published in the International Medical Journal JAMA Network Open yesterday, August 22, 2022.
the essence is
One strain of the COVID-19 virus The average incubation period (meaning ‘time from infection to symptom onset’) is consistently shorter.
from the alpha species The onset of infection to symptoms took approximately 5 days (confidence interval from 4.94-5.06 days).
Beta strain lasts 4.5 days (confidence interval from 1.83-7.17 days).
Delta species (The worst outbreak last year) lasted 4.41 days (Confidence interval from 3.76-5.05 days).
And the latest Omicron species that has spread this year Shortened to 3.42 days (confidence interval from 2.88-3.96 days)
This research indicates that Alpha and beta species have approximately the same incubation period. with the original strain that began to spread in Wuhan (regarding 5.2 days).
but following Later outbreaks Since the middle of last year, Delta and Omicron have markedly shorter incubation periods.
An overview of all past outbreaks The mean incubation period for all species studied was 6.65 days (confidence interval from 6.31-6.99 days), with the shortest 1.8 days and the longest 18.87 days.
By categorizing the disease by severity, it was found that those who were infected with severe illness tended to have a shorter incubation period than those who were infected with less symptoms.
While the children (8.82 days, 8.19-9.45 days confidence interval) and the elderly (7.43 days, 5.75-9.11 days confidence interval) had a longer incubation period than the average of the population.
Benefits of this research Help us know the nature of the disease. and keep an eye out for any abnormal symptoms following a history of close contact with an infected person or following the risk
…in the ongoing epidemic situation Everyday life requires awareness and attention to the health of oneself and family members.
Wearing a mask correctly and consistently is the key to greatly reducing the risk.
