With over 1.6 million people infected worldwide, and the number of dead has surpassed 100,000, testing for signs of fever may not be enough alone to prevent the spread of the most virulent flu to hit the planet since the 1918 Spanish Flu epidemic.
The logic behind testing for signs of fever is that those who present with a high fever (considered to be 38 degrees C and over) can immediately be identified for isolation and quarantined depending on the severity of the symptoms. However, the indications for Covid-19, or SARS-Cov2 to give it the proper name, are more than just temperature. So testing for temperature alone as a primary indication of exposure falls short of the preventative measures that we need to take in order to prevent further spread.
Furthermore many who have had an actual test performed have tested as positive while presenting as asymptotic. This further complicates the task that we are faced with.
While a high temperature may be an indication of Covid-19, it may also be indicative of other communicable diseases too such as those that are described by the broad term ‘flu’. A high temperature may also be an indication of non-communicable diseases too such as malaria. Other causes include side effects of medication, arthritis, adrenal issues, hyperthyroidism and many others related to non-communicable diseases.
Testing needs to mature quickly so that we are able to make decisions with greater confidence.
