BANDAR SERI BEGAWAN, Sept 16 (Borneo Bulletin/ANN): A total of 3,835 cases have been reported since the second wave began on August 6, of which 3,791 (98.9 per cent) were local transmissions, with 44 imported cases.
Meanwhile, 27.9 per cent of the cases were children and adolescents aged 19 and below.
The vital analysis and findings on the second wave of the Covid-19 outbreak in the country, as of September 12, was provided by Minister of Health Dato Seri Setia Dr Mohd Isham Jaafar at the daily press conference in the capital.
Permanent Secretary at the Ministry of Health (MoH) Maswadi Mohsin also attended.
Referring to a graph in a slide presentation, the minister said, “This is a graph showing the epidemic curve for this second wave. Based on the dates, the cases underwent swab tests.
“This graph shows that, although the second wave did not show a decrease, it was however stable and did not show an increase.
"This graph also shows the ‘doubling time’, whereby the period for the number of cases to double is 20.1 days, compared to three to four days when the second wave first occurred.”
He added, “The findings are in line with the graph on Slide 3, which shows the reproduction number for the second wave, where the basic reproduction number (R-naught), which is the reproduction number when the second wave first occurred, is at level 5.
“This means that at the time, one positive case caused five new cases. Currently, the effective reproduction number of R(t), that is the reproduction number at this time, is around level 1, which means that one positive case has caused one new case.”
“The R(t) at level 1 also indicates a stable state of infection.
“The diagram on Slide 4 shows that to date, most of the cases involved in the second wave are those who have not received the COVID-19 vaccine injection, whereas 8.4 per cent from the cases are those who have completed the Covid-19 vaccine injection.
“As previously mentioned, those who have received the Covid-19 vaccine can still be infected with the SARS-CoV-2 virus, but in general, the infection they experience is mild – that is, whether they only have mild signs of infection or they do not show any signs of infection at all.”
The analysis of the cases involved in the second wave also found that the vaccine effectiveness in preventing symptomatic infections and asymptomatic infections was 75.8 per cent for those who just received one dose of the vaccine, and 82.9 per cent for those who have completed two doses of the Covid-19 vaccine injection.
“These findings indicate that despite the occurrence of the breakthrough infections, the Covid-19 vaccine injection has been shown to prevent most of the Covid-19 infections in the country,” said the minister.
“Therefore, as part of our efforts to curb the Covid-19 outbreak, the public is strongly encouraged to get the virus vaccine that is provided free of charge by the government.” - Borneo Bulletin/ANN
