There is evidence that COVID19 can be spread silently.
Although researchers are yet to bridge the gap of knowledge on understanding what category of people can be termed ‘silent spreaders’, so far, 2 categories of people have surfaced.
This knowledge is important because whether or not a person is showing symptoms, once infected, they can very well infect others.
Category 1 – Asymptomatic Patients
These are patients that do not develop symptoms; however, they can still transmit the virus.
COVID19 can be spread through exposure to respiratory droplets from coughing or sneezing.
Asymptomatic people do not meet the standard case defined by the Federal Ministry of Health for testing, as a result they are less likely to be diagnosed of COVID19.
The adverse effects are hampered efforts to limit transmission of the virus.
Category 2 – Presymptomatic Patients
There are patients who first pass through the presymptomatic phase – after infection, symptoms might not develop for five to six days – or even two weeks, yet, they are threats to others because they can easily infect others. The time between catching the virus and showing symptoms is called the presymptomatic phase.
So far, presymptomatic is a much more common category than asymptomatic.
A high percentage of people who test positive without showing symptoms turn out to be presymptomatic, displaying coughing, fatigue, fever, and other signs of COVID19 in a later follow-up exam, according to Van Kerkhove, technical lead for the WHO’s Health Emergencies Programme.
People to Consider
We must all consider the vulnerable group, seeing that the categories above are more likely to infect others unknowingly, it is imperative that we make conscious efforts to mitigate spread by adhering to social distancing measures and wearing face masks in public where social distancing may be difficult.
DID YOU KNOW?
#COVID19Nigeria data shows that infected people over 64 years are 23 times more likely to die from #COVID19 than the younger people?
