Post created on 5:00 pm


The World Health Organisation (WHO) says Nigeria is currently facing a second wave of the diphtheria outbreak.

The health organization disclosed this in a statement on Thursday stating that there has been an increase in Nigeria’s affected population with a rise in the number of confirmed cases and related deaths.

Diphtheria is a bacterial infection caused by the corynebacterium species that affect the nose, throat, and sometimes, skin of an individual.

Some symptoms of diphtheria include fever, runny nose, sore throat, cough, red eyes, neck swelling, and difficulty in breathing.

“Nigeria is currently facing a second wave of a diphtheria outbreak after a first wave of the outbreak was recorded between epidemiological week 52, 2022 (1 January 2023) and week 20, 2023 (22 May 2023),” the report reads.

“Since the last Disease Outbreak News on diphtheria in Nigeria was published on 27 April 2023, the country has reported suspected cases of diphtheria weekly to WHO.

“However, between 30 June and 31 August 2023, Nigeria recorded an unusual increase in the number of confirmed diphtheria cases.

“From 30 June to 31 August 2023, a total of 5898 suspected cases were reported from 59 LGAs in 11 states across the country.

“The majority (99.4%) of suspected cases were reported from Kano (1816), Katsina (234), Yobe (158), Bauchi (79), Kaduna (45) and Borno (33).

“Of the cumulative 8353 suspected cases reported since the outbreak was first reported in 2022, 4717 (56.5%) cases were confirmed.

“The low national coverage (57%) of the Pentavalent vaccine (Penta 3) administered in routine immunization, and the suboptimal vaccination coverage in the pediatric population—with 43% of the target population unvaccinated—underscores the risk of further spread and the accumulation of a critical mass of susceptible population in the country with sub-optimal herd or population immunity.

“This emphasizes the urgent need to strengthen diphtheria vaccination coverage nationwide, especially in the most affected states, such as Kano.”
