Expert seeks inclusion of statisticians in coronavirus contact tracing


Dr Olaniyi Olayiwola, Head, Statistics Department, Federal University of Agriculture, Abeokuta (FUNAAB), has called for the inclusion of statisticians in identifying Coronavirus cases not captured by contact tracing.

Olayiwola, also Chairman, Royal Statistical Society, Nigeria Local Group, made the call at the Lagos State Polytechnic, Ikorodu first virtual public lecture on Thursday.

The virtual lecture has as its theme ;  “Modelling COVID-19 Pandemic in Nigeria: The Lagos Experience”.

He said that statisticians needed to be included in the Nigeria Centre for Disease Control (NCDC) team because tested samples through contact tracing were unable to capture carriers at once.

 According to him, doctors can handle contact tracing while statisticians should implement the designed methodology to identify the carriers not captured by contact tracing.

“States and the Federal Capital Territory need to carry out contact tracing and the designed methodology on the same day at the same time.

“Contact tracing and the methodology design need to be done simultaneously within a state but in different locations.

“Hence, appropriate probabilistic sampling is required to sample the population in order to capture all the carriers at once,” Olayiwola said.

He noted that samples tested through contact tracing were less than required numbers to be tested.

“Therefore, the government should increase the targeted sample to at least 7,200 for NCDC to capture all the COVID-19 carriers at once.

“We have developed a model for estimating total numbers of COVID- 19 carriers in Nigeria and the model is an additional approach to contact tracing for COVID-19 carriers identification.

“Our findings show that all COVID-19 carriers will only be captured at once if contact tracing is combined with methodology designed in this work,” he explained.

The statisticians further explained that contact tracing was a process of identifying, assessing and managing

people who had been exposed to COVID-19 carriers to prevent onward transmission.

“Contact tracing helps to break the chains of transmission of COVID-19.

“Existing models for COVID-19 which can help in contact tracing include, confirmed, discharged and death cases,” Olayiwola said.

He said that the models would help to  estimate the number of hidden carriers and determine the required sample size for COVID-19 test that would capture all  carriers in the population at once.

He added that the model would also suggest better approach to handle COVID-19 for reduction of spread, death cases and government expenditure.

Nadal to skip United States Open due to COVID-19 concerns, as organisers announce entries

Published

on


World number two Rafa Nadal confirmed on Tuesday that he would not defend his United States Open crown this year at Flushing Meadows.


His announcement came as organisers released the singles entry list for the Grand Slam.

Spain’s Nadal had said in June that he had reservations about travelling to the United States amid the COVID-19 pandemic.

He joins women’s world number one Australian Ash Barty in skipping the tournament due to COVID-19 concerns.

“After many thoughts I have decided not to play (at) this year’s United States Open,” Nadal said on Twitter.

”The situation is very complicated worldwide, and the COVID-19 cases are increasing. It looks like we still don’t have control of it.

“We know that the reduced tennis calendar is barbaric this year after four months stopped with no play.

”I understand and thank (everyone) for the efforts they are putting in to make it happen. We have just seen the announcement of Madrid not being played this year.

“This is a decision I never wanted to take but I have decided to follow my heart this time and for the time being I rather not travel.”

The Madrid Open, which was scheduled to take place from Sept. 12 to Sept. 20, was cancelled on Tuesday due to the rise of COVID-19 cases in the Spanish capital.

The United States has the highest tally in the world with more than 4.7 million confirmed novel coronavirus cases and nearly 156,000 deaths, according to a Reuters tally.

World number one Novak Djokovic, a three-times champion in New York, headlines the men’s list along with last year’s runner-up Daniil Medvedev.

There are other top 10 players, including Dominic Thiem, Stefanos Tsitsipas and Alexander Zverev.

Swiss Roger Federer, a five-times United States Open champion, will also be absent after the 38-year-old was forced to undergo knee surgery in June which  prematurely ended his 2020 season.

Nine of the top 10 women’s players, including 23-times Grand Slam champion Serena Williams and holder Bianca Andreescu, are on the entry list along with 2018 champion Naomi Osaka.

As many as 13 Grand Slam champions are in the women’s draw.

These include Romania’s Simona Halep, the reigning Wimbledon champion and 2018 French Open winner, and this year’s Australian Open champion American Sofia Kenin.

The United States Tennis Association (USTA) said eight additional wildcard entries would be selected in both the men’s and women’s fields.

Organisers said the seedings would be announced closer to the start of the tournament which is scheduled for Aug. 31.

A number of players are also set to take part in the Aug. 20 to Aug. 28 Western & Southern Open in New York, which serves as a warm-up event for the United States Open.

Food sufficiency: Osun commissioner inaugurates ‘Wave City’ project

Published

on


Osun Commissioner for Agriculture, Mr Adewole Adedayo, on Tuesday  inaugurated an agricultural project, ‘Wave City,’ sited by FarmKonnect Agribusiness Nigeria Ltd at Wasimi to promote food sufficiency.


Speaking at the inauguration,  Adedayo, who described the project as the first of its kind in the state and the South-West region, said it was aimed at promoting food sufficiency, national development and agricultural inclusion.

According to him, every responsible government must create an enabling environment for farmers.

“Today, I believe FarmKonnect is now realising a dream that started in 2017. Today, having FarmKonnect in Osun State is another dream.

“Today, having these facilities on ground to develop agriculture in the south-west is a dream realised. So FarmKonnect has realised a dream.

“Like I keep saying, agriculture has the highest potentials to create jobs, both for skilled and unskilled labour. So, I will like to thank FarmKonnect for bringing this project to Osun State,” he said.

According to the commissioner, agriculture is top on the agenda of the state government.

The commissioner, who highlighted the various initiatives of the government to support agricultural development, pledged the administration’s readiness to welcome investors like FarmKonnect to the state.

“We are looking for investors like this, people who will empower our youths and also create jobs for farmers,” he said.

The News Agency of Nigeria reports that FarmKonnect was founded by Lt.-Col. Oluwole Azeez who voluntarily resigned from the Nigerian Army to invest in agriculture real estate business.

Azeez said that his organisation’s mission was to take agriculture beyond just planting crops and making money to a business which promotes food sufficiency, national development and agricultural inclusion.

“In FarmKonnect, we run a model we call agricultural real estate and we are the first to do that. This allows multiple people to own a portion of the farm and they don’t necessarily have to step on the farm.

“All they just need to do is engage their money and we take all the performances around. The greenhouses you are seeing here are specifically designed for the tropics.

“The vision is to build one million square metres of greenhouses, a controlled farming environment technology using greenhouses and net houses to produce fruits and leafy vegetables from tomatoes to pepper.

“This is the first of its kind in Nigeria. This is specifically designed for minimal electricity as well as to expand our yield,” he said.

Azeez  said he was grateful to the Osun government for its tremendous support to the project and assured it of greater benefits in terms of food sufficiency and job creation.

Also speaking, Dr Bosade Ogunlana, the Founder of Entrepreneurship Initiative, commended FarmKonnect for the project, saying it would help in empowering the youths.

According to her, Africa has more youths to engage in land cultivation in order to boost food sufficiency and security.

“Africa is the biggest gun of the world because over 60 per cent of arable land in the entire world resides in Africa. I know with something like this happening here today, there is hope for Nigeria.

“Agriculture is the new gold, there is no longer oil. There is nothing we want to do with oil. Agriculture can help us with the GDP of the economy.

“It can help us to engage the youths. It can help us to ensure there is no scarcity of food,” she said.

Ogunlana thanked the Osun government for its support to FarmKonnect, urging it to ensure adequate security for the project.

NAN reports that the event,  which also featured the unveiling of the tomato statue and facility tour, was held in strict adherence to COVID-19 protocols.

The event was also attended by Mr Yemi Lawal, the Commissioner for Youth and Sports in Osun, as well as representatives of the various partners of FarmKonnect.

Published

The Lagos State Waterways Authority (LASWA) on Tuesday said that it had impounded engines of six passengers’ boat operators in its renewed efforts to sanitise waterways to prevent boat mishaps.


Its General Manager, Mr Oluwadamilola Emmanuel, disclosed this in a statement in Lagos by Mrs Nkechi Ajayi, the Public Affairs Officer of LASWA.

The News Agency of Nigeria reports that there have been reports of accidents on waterways in Lagos in recent times, the latest being July 29, which claimed more than 10 lives.

Emmanuel expressed LASWA’s commitment to continually ensure the safety of ferry passengers in the state.

According to him, the arrest of erring boat operators is part of the authority’s efforts in the ongoing enforcement and monitoring exercise across the inland waterways.

“The patrol team of Lagos State Waterways Authority (LASWA) earlier today seized a total number of six boat engines belonging to commercial ferry operators that were caught flouting safety regulations on the waterways.

“Their offences include: not wearing life jackets, overloading, reckless driving, among other offences which could have resulted in preventable fatalities when accidents occur,” the LASWA boss said.

According to him, areas covered during today’s safety compliance operations were Mile 2, Kirirkiri, Abule Osun Jetty, Alex Jetty, Liverpool, Ebute-Ojo all in the Ojo axis of Lagos.

Emmanuel reassured that the authority would no longer condone any action that would be against the safety standards of the state inland waterways.

“Any erring operator will be sanctioned appropriately,” the general manager said.

According to him, the authority will work harder on boat captains and deckhands while continuing sensitisation, awareness and enlightenment to foster safety on waterways.
