Bangladesh registered 32 more deaths and 1,567 new cases and 2,051 recoveries from coronavirus in 24 hours till Saturday morning.
The recovery rate from Covid-19 reached 73.23 percent as 2,051 patients got cured from the disease during the period raising the number of total recoveries to 2,54,386 since March last.
So far, 4,913 people died due to the deadly disease, according to an official release sent by the Directorate General of Health Services (DGHS).
Besides, the daily infection rate in Bangladesh declined to 11.90 percent during the period as the new patients were detected after the test of 13,170 samples.
With the latest figure, the number of total cases rose to 3,47,372 which is 19.20 percent of the total tested population.
Currently, there are 88,073 active cases in the country. Bangladesh is seeing 1,493.70 recoveries per million while 28.85 are dying against the same number.
Since March 18, the release said 3,829 men and 1,084 women have died from the disease.
Of the 4,913 victims, the highest 2,477 are above 60 years of age, 1,336 between 51 and 60 years, 636 between 41 and 50 years, 288 between 31 and 40 years, 113 between 21 and 30 years, 42 between 11 and 20 years and 21 others are below 10 years.
So far, 2,404 people have died in Dhaka division, 1,022 in Chattoram, 329 in Rajshahi, 415 in Khulna, 184 in Barishal, 221 in Sylhet, 231 in Rangpur and 107 have died in Mymensingh divisions.
Across the country, 17,032 people are now in isolation and 47,355 in quarantine.
In Bangladesh, the first three cases of coronavirus infection were detected on March 8 and it crossed 3,00,000 on August 26.
On July 2, a total of 4,019 Covid-19 patients were identified in the country which was the highest in a single day.
A team of scientists from Noakhali Science and Technology University (NSTU) and North South University (NSU) has claimed to make the first and successful attempt to detect SARS-CoV-2 viruses' genetic material in the sewage water.
The team is led by Professor Firoz Ahmed, Chairman Dept. of Microbiology, Noakhali Science and Technology University (NSTU), said a media release issued by NSTU on Saturday.
They collected specimens in between 10th July and 29th August, 2020 from drain, sewage and toilets near Shaheed Bhulu Stadium Detention Centre dedicated for COVID-19 patients at Noakhali, Bangladesh.
The team "successfully detected" several genes including ORF1ab, and N protein genes, from the sewage water samples, it said.
While the wastewater surveillance of COVID-19 has been focused on wastewater treatment plants around the world, the researchers opted for drain waters monitoring in the vicinity of isolation center, which is first of its kind.
Apart from this being the first detection report of SARS-CoV-2 RNA in the wastewaters of Bangladesh.
The uniqueness of the study has been the tracing of genetic load in the vicinity of isolation center that contains almost the constant number with COVID-19 patients.
This has been the key feature of this study as most of the study reported worldwide has either reported total infected person in the city or country, said the media release.
However, the critical observation has been the temporal variation where small drains showed reduction of genetic load, the bigger canal and main sewer city exhibited temporal accumulation of SARS-CoV-2 RNA.
On the other hand, distance of sampling location in meters appears to be insignificant from the perspective of wastewater surveillance of COVID-19.
According to the renowned virologist and former Vice Chancellor of BSMMU Professor Dr. Nazrul Islam, it is internationally recognized the presence of COVID-19 in the gastro intestine system and therefore, the method developed by the team to identify the presence of COVID-19 in the sewage water could serve as a tool to prevent the future spread of the disease.
Prof. Nazrul considers the initiative of the group as a remarkable achievement in developing an effective waste water surveillance system in Bangladesh.
"Wastewater is an important source to monitor the presence and progress of the infection because the virus leaves the body of not only those who are symptomatic but also asymptomatic individuals through excretion," said NSTU Professor Firoz Ahmed, who is leading the ongoing preliminary research.
He also added “Our finding effectively substantiates the ability of wastewater surveillance to enormously supplement testing individuals who are infected or incubating that virus which causes COVID-19."
Vice Chancellor of the NSTU, Professor Dr. Didar-ul-Alam said they are running Covid-19 Diagnostic Laboratory with the voluntary support of faculties, staff & students since May 2020.
"In the meantime, our lab has performed about 21000 SARS-CoV-2 RT-PCR tests to serve for the peoples of ten upazilas of Noakhali and Laxmipur Districts with the financial support of our university. I am very happy with the research findings the existence of Covid-19 genetic materials in the waste waters as revealed by our team during the global pandemic. This will help to establish national surveillance on tracking the routes of Covid-19 virus spreading and its interplay with the environment”.
The team consists of Prof. Md. Jakariya, PhD, Dr. Maqsud Hossain, Prof. Hasan Mahmud Reza from North South University and Prof. Firoz Ahmed, Prof. Dr. Newaz Mohammed Bahadur, Foysal Hossen, Md. Shahadat Hossain, Aminul Islam, Md. Main Uddin, Md. Nur Islam from Noakhali Science and Technology University.
Criminal Investigation Department (CID) have arrested eight officials including engineers of Titas Gas Transmission and Distribution Company Ltd in connection with the blasts at a mosque in Nayaranganj that left 32 people dead .
CID’s acting DIG Moinul Hasan disclosed the information at the Police Superintendent’s office here on Saturday.
The arrestees are Fatullah zonal office manager engineer Mohammad Sirajul Islam, deputy manager Mahmudur Rahman Rabbi, assistant engineer SM Hasan Shahriar, assistant engineer Manik Mia, senior supervisor Md Manibur Rahman, senior development officer Md Aiyub Ali, helper Md Hanif Mia and Md Ismail Prothan.
Moinul Hasan said they were arrested from their respective areas in Fatullah.
Around 40 people were injured in the blasts at Baitul Salam Jame Mosque i mosque in Fatullah after Esha prayer on September 4.
Of them, 37 were taken to the Dhaka hospital in critical condition and 32 of them have died so far.
A man and his minor son were killed and 12 other people injured following a collision between a pick-up van and a microbus on Mymensingh-Kishoreganj highway in Dangri area of Nandail upazila on Saturday morning.
