Chikungunya on the Rise Again, WHO Issues Global Warning

Published

By Onyeanya Ebere Immaculata

The World Health Organization (WHO), has issued an urgent alert over the global resurgence of chikungunya, a mosquito-borne viral disease, following major outbreaks in La Réunion, Mayotte, and Mauritius since March 2025.

Although Nigeria is not currently affected, public health experts warn that the country’s environmental conditions make it highly vulnerable.

WHO reports the outbreaks are rapidly spreading to South and East Asia, mirroring patterns from two decades ago when a chikungunya wave from the Indian Ocean infected nearly 500,000 people worldwide.

The agency described the current trend as “highly concerning,” cautioning that failure to act swiftly could trigger a global public health emergency.

So far in 2025, over 200,000 cases have been reported in the Americas. Approximately 5.6 billion people now live in regions suitable for Aedes mosquitoes, the primary vectors of chikungunya, dengue, and Zika viruses.

Chikungunya has been detected in 119 countries, with infection rates as high as 75% in communities with low immunity, often overwhelming healthcare systems.

Dr. Diana Rojas-Alvarez, WHO’s Technical Lead for Arboviruses, stressed the need for early preparedness: “We are raising the alarm early so countries can prepare through surveillance, mosquito control, and public awareness to avoid overwhelming health services.”

In Nigeria, Aedes aegypti mosquitoes are widespread, particularly in Lagos, Abuja, and other urban centres, where poor drainage and stagnant water provide ideal breeding sites.

Experts warn that urban crowding and the rainy season increase the risk of outbreaks.

With increased international travel, the risk of chikungunya importation into Nigeria is real.

Epidemiologists caution that a single imported case in a densely populated area could trigger a rapid outbreak if surveillance is lacking.

So far, the Nigeria Centre for Disease Control and Prevention (NCDC), has not issued a specific chikungunya alert in 2025.

Chikungunya is transmitted by day-biting Aedes aegypti and Aedes albopictus mosquitoes.

Symptoms include sudden high fever, severe joint pain, rash, muscle pain, headache, fatigue, and nausea.

While fatalities are rare, newborns, the elderly, and those with chronic illnesses are at higher risk.

Some patients experience prolonged arthritis-like joint pain lasting months.

There is no specific antiviral treatment; care focuses on rest, hydration, and pain relief, with aspirin and NSAIDs generally discouraged.

Prevention depends largely on mosquito control: eliminating breeding sites, using repellents, and wearing protective clothing.

First identified in Tanzania in 1952, chikungunya has caused significant outbreaks across Africa, Asia, the Indian subcontinent, Europe, and the Americas.

The largest outbreak occurred in India (2005–2006), affecting over 1.9 million people.

Residents Query PCN Over Pharmacy at Abuja NNPC Station

Residents of Life Camp, Abuja, are raising safety alarms over the Pharmacy Council of Nigeria’s (PCN), approval of an H-Medix outlet situated within an NNPC Limited filling station.

Locals argue that selling medication in close proximity to fuel pumps exposes pharmaceutical products to toxic fumes and fire hazards.

Resident Cyril Chizoba warned of “serious health risks,” including chemical contamination, while medical expert Dr. Gaius Mikinta noted that volatile environments can compromise the efficacy of temperature-sensitive drugs.

In response, PCN Legal Head Abana Lawan confirmed the outlet is duly licensed.

He stated that approval was granted after a “demarcation” within the premises met regulatory standards, adding that the move helps prevent monopolies and expands service access.

However, PCN Registrar Pharm. Ibrahim Babashehu Ahmed declined to comment further during a recent press visit.

Despite official assurances, the community is calling for an independent inspection. “I was surprised regulators approved this,” said Solomon Dauda, a local driver, noting the daily dispensing of petrol and gas at the site.

Residents continue to demand greater transparency to ensure pharmaceutical standards aren’t being traded for convenience.

FCT Nurses Condemn Attacks on Colleagues

The National Association of Nigeria Nurses and Midwives (NANNM), FCT chapter, has condemned the attack on a nurse at Wuse General Hospital by suspected “one-chance” criminals.

The nurse, who stayed after her shift to assist a colleague in the ICU, was allegedly beaten and left seriously wounded. She is receiving treatment.

The union said attacks on healthcare workers in the FCT are becoming frequent, with nurses now living in fear during early mornings and late evenings. It urged the Minister of the FCT, Nyesom Wike, and security agencies to strengthen patrols around hospitals and vulnerable bus stops.

“No healthcare worker should risk their life simply for serving humanity,” the statement said. “Bus stops around hospitals have become death traps. We demand immediate and sustained action to protect all nurses.”

The attack follows earlier incidents, including the killing of nurses Chinemerem Pascalina Chuwumeziem and Princess Ochigbo in January, allegedly by one-chance gangs.

Analysts link the crimes to gaps in organised public transport, forcing reliance on unregistered taxis and private vehicles during off-peak hours.

The association had previously called on authorities to improve hospital security and provide safe transport for healthcare workers.

FIIRO Warns: Local Grinding Machines May Trigger Organ Failure, Heart Diseases

By Onyeanya Ebere Immaculata

The Federal Institute of Industrial Research, Oshodi (FIIRO), has warned that rising cases of organ failure and cardiovascular diseases in Nigeria may be linked to foods processed with locally fabricated grinding machines.

FIIRO’s Director General, Dr. Jummai Adamu Tutuwa, disclosed this while briefing journalists, citing research findings by the institute.

She said an assessment conducted in 2013 found that several locally made grinding machines used for processing tomatoes, pepper, onions, melon seeds and other food items, particularly within Lagos, contained traces of heavy metals.

According to her, the metals identified included lead, copper, chromium, nickel, cadmium and manganese. The study also detected other metals such as calcium, magnesium, zinc and iron.

She noted that in some cases, contamination levels exceeded safety limits set by the World Health Organisation (WHO), and the Food and Agriculture Organisation (FAO), especially in areas exposed to heavy traffic and industrial activities.

Dr. Tutuwa explained that while some metals occur naturally, they become dangerous due to bioaccumulation, non degradability and high concentration in the food chain.

She warned that prolonged consumption of contaminated food could contribute to increased cases of organ failure and cardiovascular diseases, even among young adults.

To curb the risk, she said FIIRO has developed a stainless steel pepper grinding machine designed to reduce food contamination.
