Due to an ineffective disease reporting system, it has become difficult to collect data on disease patterns in the community hence making data-guided decision making difficult.
As medical doctors in a primary care hospital, we notice changes in disease patterns in the community but our history is collected on paper and disease surveillance is ineffective. At last quarter of 2019, we noticed a wave of febrile medical condition which was occasionally associated with some upper respiratory symptoms which almost overwhelmed our hospital. This pattern was noticed across different hospitals in Lagos state but we did not have a system that monitors these patterns.
Similarly, when COVID 19 was labelled a pandemic 2020, we noticed certain disease patterns before we saw these things in publications. For example, we noticed that some a strong association between COVID and hyperglycaemia or COVID and vertigo before we saw journals written about them. And all the waves of infection that were announced were usually noticed a week or two before we hear the announcement that there is a wave. We notice these waves by seeing an uptick in the symptoms patients were presenting with.
If we want to be able to prevent future pandemics, it is imperative that we have a system that detects change in disease patterns early. Especially, viral infections so action can be taken.
