Over 160million people – more than half of Nigeria’s current estimated population – are at risk of yellow fever, according to reports by the World Health Organisation (WHO), Africa Region.
According to the WHO, the virus is spreading rapidly across Africa, warning that the rising trend could cause an epidemic in Nigeria particularly, mainly because of its large population. Consequently, it issued an advisory for travellers to and out of the country to consult their health care providers on precautionary measures required against the virus if need be.

The disease is potentially fatal as half of its patients in the toxic phase die within seven to 10 days.
The demography of Nigeria is one of the most important and common reasons the fever could spike in the country. Nigeria is one of the countries that is most vulnerable to the yellow fever virus, according to the WHO, and has a history of poor health infrastructure.
Additionally, the Nigerian population is largely uninformed about health and hygiene precautions, a situation that makes them particularly susceptible to the virus.
The Nigeria Centre for Disease Control (NCDC) said yellow fever epidemic in Nigeria could spike in the coming weeks. This becomes worrisome due to the fact that there is no treatment for the virus.
However, the good news for most people is that a single dose of yellow fever vaccine gives a long-term protection.
Travellers going to areas with an outbreak are usually encouraged to consider taking a booster dose of the vaccine. This recommendation is particularly important to those who have been vaccinated 10 years ago or more from the period of the first shot. In some countries, a booster dose of the vaccine is a requirement for entry.
For health-conscious minds who understand the magnitude of such alarm, panicking is a reflex possibility. However, protection and precaution, especially for travellers, have proved time and again to be an effective weapon in curbing epidemics.
To effectively achieve this, WHO’s fact sheet outlines these measures to include avoidance of close contact with people who are sick or even appear so; staying away from mosquito-infested areas; using of mosquito repellents to ward them off; lodging in hotels that have been well-screened, and consulting a health care professional about specific needs.
While precaution and protection remains key, it is also essential for us to be well acquainted with its symptoms, which include fever, chills, headache, muscle pain and back pain. Other symptoms are nausea, vomiting, fatigue, weakness and rash.
Most people with the initial symptoms improve within one week, while others will develop a more severe form of the disease, which includes symptoms such as high fever, yellow skin (jaundice), bleeding (mouth, nose, eyes, stomach), abdominal ache and organ failure (liver and kidneys).
Although vaccines work and are the only form of treatment available,certain people should not be vaccinated because complications (side effect) could arise due to underlying ailments and treatment they are undergoing. This includes organ transplant recipients, individuals diagnosed with a malignant tumor, those diagnosed with thymus disorder associated with abnormal immune function, and patients diagnosed with a primary immunodeficiency.
Other categories include individuals using immunosuppressive and immunomodulatory therapies, those allergic to a vaccine or something in the vaccine (like eggs). Symptoms of an allergic reaction include difficulty in breathing, swelling of the face and throat and hives. If any of the symptoms is experienced after receiving the vaccine, medical attention should be sought immediately.
To spread, all diseases require a medium, be it air, water, insects and so on. Yellow fever virus being a viral disease is spread through the bite of an infected aedes aegyti mosquito, which serves as the vector of the deadly disease. Worthy of note is that direct spread from person to another does not occur.
It is, therefore, expedient for individuals and businesses in Nigeria to be aware of the yellow fever virus and take the necessary measures to avoid being infected. By following the guidelines of health professionals and organisations, protection of oneself and those around from this dangerous disease is achievable.
