COVID-19: Mitigating Impact Among Vulnerable Population

Posted: 15-07-2020 01:21:30 PM

Research on the coronavirus disease (COVID-19) has shown that among populations, some people are at considerably higher risk of having severe complications from the disease. As of the 13th of July 2020, a total of 566,654 deaths have been recorded globally while in Nigeria, a total of 744 deaths have been recorded. Analysis of the case fatality ratio (CFR) in various countries have shown deaths occurring mainly in older adults or persons with underlying health conditions.

The Nigeria Centre for Disease Control (NCDC) recently published an updated version of the Advisory for Vulnerable Groups, providing specific guidance on how they can stay protected and reduce the risk of being infected. In line with the context of COVID-19 in Nigeria, people in the following category are considered vulnerable:

1. Persons aged 50 years and older (with or without underlying illnesses)

2. Persons with critical underlying medical conditions such as diabetes, cancer, lung disease, liver disease, moderate to severe asthma etc.

3. Other persons who have been assessed as vulnerable, based on clinical assessment

With the gradual reopening of socioeconomic activities nationwide and ongoing community transmission, the risk of being infected is higher particularly where there is inadequate adherence to recommended preventive measures. Below are key excerpts from the advisory, for vulnerable groups, on how to stay safe and protected from COVID-19:

1. Use of non-contact greetings

2. Practice hand hygiene, cough etiquette etc.

3. Avoid non-essential outings, visitors and large gatherings. Always maintain a distance of at least 2 metres of distance between yourself others while in public

4. If possible, consider having your medicines, groceries and essential items delivered to your home by a designated close person who complies with recommended measures including the use of face mask use and hand hygiene

5. If you have to work, discuss and agree your options with your employer to enable you work from home or make changes within the office space to keep you and your colleagues protected

6. If you do share a toilet and bathroom with others, ensure they are cleaned after each use

7. Disinfect frequently touched surfaces e.g., door handles, light switches, TV remotes etc.

8. Where possible, sleep in a different bed and do not share towels, cutlery, drinking cups etc.

9. Keep shared spaces well ventilated and minimise the time spent in shared enclosed spaces, such as kitchens, bathrooms and sitting areas

10. Immediately call your state helpline and a close family member if you develop symptoms of COVID-19 or believe you have been a close contact of a confirmed case.

The NCDC will continue to provide necessary guidelines and public health advisories to ensure Nigerians are protected from COVID-19.
