Can mosquitoes spread SARS-CoV-2?

Published

The answer is “no,” according to Dr. Daniel Markowski, technical advisor for the American Mosquito Control Association.

“There is no evidence that mosquitoes can acquire and transmit the SARS-CoV-2 virus,” he told MNT.

In order to understand the mechanisms that prevent mosquitoes from carrying and spreading the SARS-CoV-2 virus, Dr. Markowski explained it is important to understand how mosquitoes transmit virionsTrusted Source, or viral particles.

“Typically, the mosquito must first feed on an infected host, that is circulating enough virus in their blood to have some present in the small amount taken during a mosquito’s blood meal,” he explained.

“Secondly, the virus must survive the insect’s midgut, which has a host of immune responses similar to our own. Not only must they survive inside the mosquito’s midgut, they need to replicate and ultimately bind to receptor sites on the wall of the midgut and pass through that barrier into the mosquito’s body cavity,” Dr. Markowski added.

Once inside the body cavity, Dr. Markowski explained that the virus needs to get past the mosquito’s immune system and make its way into the insect’s salivary glands, all while continuing to replicate.

“Now with the next blood meal, they can be passed to a new host while the mosquito feeds,” he continued. “As you can see, it’s a fairly long and complex journey each virus makes to go from one host to the next via a mosquito bite. And not many viruses have evolved over the millennia to successfully complete that journey, which is why many viruses such as flu, coronavirus, and monkeypox are not mosquito-borne viruses.”

In July 2022, a team of researchers including Dr. Stephen Higgs, associate vice president for research and director of the Biosecurity Research Institute at Kansas State University, published a studyTrusted Source that found that even under extreme conditions, the SARS-CoV-2 virus did not replicate in mosquitoes.

Because of this, the researchers stated, mosquitoes would be unable to transmit the virus to people even if the mosquito fed upon someone infected with the SARS-CoV-2 virus.

“We really did not expect that it would infect mosquitoes because, for whatever reason, coronaviruses just do not infect mosquitoes or other arthropods,” Dr. Higgs told us.

“What we did in our original paper was to inject SARS-CoV-2 into mosquitoes. We know that by using this approach you can sometimes infect a resistant mosquito with a virus that would not normally infect it. Even with that unnatural approach SARS-COV-2 did not infect and multiply in the mosquitoes,” he noted.

Rep Oseni Backs Ajimobi Widow’s Cancer Fight, Vows More Health Projects

Published

The lawmaker representing Ibarapa East/Ido Federal Constituency in the House of Representatives, Aderemi Oseni, has pledged to support the breast cancer awareness programme of the ABC Foundation founded by former Oyo First Lady, Dr. Florence Ajimobi.

Oseni, who is Chairman of the House Committee on Federal Roads Maintenance Agency (FERMA), made the commitment on Thursday in Ibadan at the flag-off of Pink Month 2025, an initiative of the foundation.

Contained in a statement by his media aide, Idowu Ayodele, the lawmaker described the campaign as a “lifesaving mission” given the rising burden of breast cancer in Nigeria, with over 28,000 new cases and thousands of deaths reported annually.

The APC chieftain said the free screening of 1,000 women planned by the foundation was timely, stressing that early detection remained the strongest weapon in the fight against cancer.

Hon. Aderemi Oseni exchanging pleasantries with former Oyo State First Lady, Dr. (Mrs.) Florence Ajimobi, at the event.

“Health is life. Only this June, I moved a motion at the National Assembly which led to the Federal Government subsidising dialysis treatment nationwide. Today, dialysis is either free or heavily discounted in federal health facilities,” Oseni said.

He listed his personal interventions to include funding hospital bills of indigent patients, construction of hospitals in Ido and Ibarapa East, establishment of primary health centres, and organisation of medical outreaches. He also disclosed plans to deploy mobile clinics to rural areas.

Commending Mrs. Ajimobi for sustaining her late husband’s legacy through humanitarian service, Oseni assured of partnership with the foundation, saying women’s wellbeing and empowerment remained central to his vision for Oyo State.

In her remarks, Mrs. Ajimobi said the foundation had offered medical care to over 85,000 patients and conducted more than 100,000 investigations since its inception. She added that the campaign was not just corporate social responsibility but “a moral duty and sacred trust.”

The former first lady, who lost her daughter Abisola to breast cancer earlier this year, said the experience had strengthened her resolve to save other families from such tragedy. She appealed to women to take advantage of the free screening and called on partners and development agencies to support the fight.

The initiative followed the unveiling of the Geneith Health Competition on the institution’s campus on Tuesday.

The competition, organised by CEOAfrica in partnership with Geneith Pharmaceuticals Limited and powered by Coatal Forte Softgel, targets students of tertiary and secondary schools nationwide to spread knowledge on malaria prevention.

Convener of the project, Mr. Cletus Ilobanafo, said the programme was designed to raise awareness through a structured health contest at the state, regional and national levels.

He said Geneith Pharmaceuticals has committed N1 billion to the project, with N400 million earmarked for scholarships and N600 million for gift items to motivate participants. “By promoting education and prevention strategies, this competition underscores the dedication of all stakeholders in combating malaria and improving public health in Nigeria,” Ilobanafo added.

The Provost of the College, Dr. Chidi Okpeze, praised the organisers for selecting the institution as a launch platform for the campaign. He expressed gratitude to President Bola Tinubu and Minister of Livestock Development, Alhaji Idi Mukhtar Maiha, for their commitment to repositioning the livestock sector to boost national growth.

“Our students are ready to key into this initiative. They are articulate, active, and have represented us well in international competitions. We are confident they will excel in this campaign too,” he said.

The Provost urged the students to brace up for the task ahead and uphold the institution’s tradition of excellence.

Some students, who spoke on behalf of their colleagues, pledged to support the anti-malaria campaign by intensifying environmental sanitation on campus. They also commended the organisers and sponsors for giving them the opportunity to contribute to the fight against malaria.

They promised to sustain clean surroundings and spread the message beyond the school to ensure malaria is eradicated from the system.
