Why Omicron Symptoms Are Milder – Study

There are new clues as to why the Omicron variant may produce milder COVID-19 symptoms, despite being more transmissible.

Several recent studies that looked at the effect of the virus on mice and hamsters have found that the Omicron variant leads to a lower viral load in the lungs and less damage to the tissues compared to previous variants.

One study from Belgian researchers published online looked at how Omicron infected Syrian hamsters.

The researchers found that the hamsters with Omicron had a 99.9 per cent lower viral load in the lungs compared to hamsters infected with older strains of the virus.

Syrian hamsters have been considered an important tool for COVID-19 research, as these animals are known to be highly susceptible to getting seriously ill from the virus.

A similar study looking at Syrian hamsters and led by British researchers was also released on Dec. 26. The researchers compared 11 hamsters infected with the Omicron variant to six infected with previous variants, including Delta.

They found that Omicron-infected hamsters had fewer signs of weight loss, ruffled fur and breathing difficulties — all of which are clinical signs of COVID-19 in Syrian hamsters.

“Further investigation is required to conclusively determine whether Omicron is less pathogenic in Syrian hamsters and whether this is predictive of pathogenicity in humans.”

A third study that looked at both mice and Syrian hamsters was published by U.S. and Japanese researchers on Dec. 29. Once again, the researchers found that rodents with Omicron had less weight loss and a lower viral load in their respiratory tracts.

The Omicron-infected rodents also had less damage to the lung tissues, suggesting that the variant can’t replicate as well in the lungs.

Another U.K.-led study published on Dec. 30 looked at the effect of Omicron on mice. Much like the studies that looked at hamsters, the researchers found that the mice infected with Omicron lost less weight and had better signs of recovery compared to mice that had the Delta variant and other older strains.

Oral swabs were also taken from all of the mice two, four and six days after infection. The viral loads in the lower and upper respiratory tract were found to be 100-fold lower in the mice with Omicron.

“Our results, and emerging from human observational studies, suggest that the Omicron variant may lead to less severe and/or more rapid recovery from clinical disease reflected in reduced hospitalization,” the authors wrote.

However, the researchers warned that the high transmissibility of the new variant could still inundate hospitals, despite evidence of milder symptoms.

“The higher transmissibility could still place huge burden upon health care systems even if a lower proportion of infected patients are hospitalized,” they wrote.

The Lagos State Government, through the Lagos State Primary Health Care Board, has launched the 2025 Polio Outbreak Response Campaign, reaffirming its commitment to eradicating polio and safeguarding the health of its children.

The ceremony, held at the Simpson Primary Healthcare Centre, was led by the First Lady of Lagos State, Dr. (Mrs.) Claudiana Ibijoke Sanwo-Olu, represented by Mrs. Widad Jumoke Mustafa, a member of the Committee of Wives of Lagos State Officials (COWLSO).

In her address, the First Lady emphasised the state government’s proactive measures to keep Lagos polio-free, highlighting the critical importance of the campaign in preventing the debilitating effects of poliomyelitis, which can result in paralysis or death.

The First Lady also called on parents, community leaders, and stakeholders to support the campaign by ensuring eligible children are vaccinated.

Targeting children aged 0-59 months, vaccination teams will administer the Oral Polio Vaccine (OPV) to prevent virus transmission.

Dr. Kemi Ogunyemi, the Special Adviser on Health, expressed gratitude to Lagosians for their continued cooperation in the fight against polio. While appreciating all healthcare workers and partners for their services, Mrs. Ogunyemi encouraged parents to present their children and wards for the exercise.

Also speaking, the Chairman of Lagos Mainland Local Government, Mrs. Omolola Rashidat Essien opined that Immunization is key in ensuring that children are kept safe from polio and other vaccine preventable diseases.

Dr. Abimbola Bowale, the Supervising Permanent Secretary, Lagos State Primary Health Care Board, who also spoke at the event, underscored the life-saving importance of immunization.

“All children aged 0-59 months need multiple doses of the polio vaccine to ensure full protection. Any child missed represents a potential risk for the poliovirus to spread. The vaccine is safe, effective, and crucial in keeping our communities polio-free,” he stated.

Dr. Bowale also outlined several strategies to ensure the success of the campaign, including fixed post teams stationed at primary healthcare centres and public health facilities, house-to-house visits, and a transit strategy to reach special locations such as places of worship, schools, motor parks, and other public venues.

The event concluded with Dr. (Mrs.) Claudiana Ibijoke Sanwo-Olu officially launched the campaign, marking a renewed effort to maintain Lagos State’s polio-free status.

The Lagos state suspected cholera cases have risen to 421.

The Commissioner for Health, Akin Abayomi disclosed this on his Instagram handle @profakinabayomi on Saturday.

“As of June 20, 2024, an additional four suspected cholera cases have been reported, as illustrated in the accompanying graph,” he wrote.

He noted that the Emergency Operations Centre in collaboration with all relevant partners is actively engaged in contact tracing, community-based surveillance, awareness campaigns, sample testing, and ensuring that confirmed cholera cases receive appropriate medical treatment.

On Friday, the commissioner confirmed 35 cases out of the 417 suspected cases and 24 deaths across 20 Local Government Areas in the state.

The cases were reported from Agege, Badagry, Ikeja, Mushin, Ajeromi-Ifelofun, Epe, Ikorodu, Ojo, Alimosho, and Eti-Osa.

Others were Kosofe, Oshodi-Isolo, Amuwo-Odofin, Ibeju-Lekki, Lagos Island, Shomolu, Apapa, Ifako-Ijaiye, Lagos mainland, and Surulere.

Cholera is a food and water-borne disease caused by ingesting the bacteria— Vibrio cholerae — in contaminated water and food. Cholera can cause severe acute watery diarrhoea, and the severe forms of the disease can kill within hours if left untreated.

In Nigeria, cholera is an endemic and seasonal disease, occurring annually mostly during the rainy season and more frequently in areas with poor sanitation.

The World Health Organisation on Thursday announced a spike in cholera in several regions of the world, with almost 195,000 cases and over 1,900 deaths reported in 24 countries since the start of 2024.

WHO said the Eastern Mediterranean Region reported the highest number of cases, followed by the African Region, the Region of the Americas, the Southeast Asia Region, and the European Region.

The global health body, however, noted that there are no reported cases in the Western Region, according to its bulletin released on Wednesday.

It said it exhausted its global stockpile of Oral Cholera Vaccines by March but was able to exceed “the emergency target of five million doses in early June for the first time in 2024.”

AUTISM: What You Need To Know

Autism, commonly known as Autism Spectrum Disorder (ASD), is a neurodevelopmental disorder that affects communication, social interaction, and behavior. Autism is referred to as a spectrum condition since it can manifest in a variety of symptoms and abilities. While the actual cause of autism is unknown, evidence suggests that genetic and environmental factors interact to influence its development.

The risk factors include a sibling with autism, advanced age of parents, exposure to certain air pollutants and pesticides before birth, extreme prematurity, mothers with diabetes, immune system disorders or obesity, any difficulty with delivery leading to deprivation of oxygen to the baby’s brain, fever during pregnancy, lack of certain vitamins minerals during pregnancy, and certain genetic conditions, such as Down, fragile X, and Rett syndromes.

“Risk factors can not on their own cause a disease. However, they can increase the likelihood of that disease in a person.”

It is important to know that contrary to trending claims online, there is no scientific or medical evidence that vaccines or consumption of sugar are risk factors for autism.

Autism is defined by difficulties in social interaction and communication. Individuals with autism may struggle to grasp social cues, maintain eye contact, and engage in typical back-and-forth conversations. Some people may also engage in meaningless, repetitive actions, such as hand-flapping or rocking, and have strong interests in specific areas.

It is essential to remember that autism is a lifelong diagnosis, but with early intervention and adequate care, people with autism can live fulfilling lives.
Autism treatment frequently includes behavioral therapy, speech therapy, occupational therapy, and social skills training. Each individual with autism is unique, thus interventions should be tailored to meet their personal needs and strengths.

In spite of the difficulties that autism can cause, many people with autism possess unique talents and abilities. Some people may succeed in fields such as music, art, mathematics, or programming, thus it is important for society to acknowledge and honor the qualities and achievements of people with autism.

In summary, autism is a complicated and diverse disorder that affects individuals in various ways. By raising autism knowledge, understanding, and acceptance, we can build a more inclusive society in which people with autism can thrive and attain their full potential.
