A Little Basic Science

One positive benefit from COVID-19 is that it reminds us of some basic science, such as the differences between a bacterium and a virus.

COVID-19 is a specific strain of virus.  The damage it does within someone's system can cause other/secondary infections, such as pneumonia.  Pneumonia is a bacterial infection.  So, what is the difference?

When we have a virus, we need to self-isolate, drink plenty of fluids, eat lightly and rest.  (It’s best to get an annual flu-shots early, especially if you are at high-risk). 

Typically, if you are not someone at risk (such as someone with weakened health – see below) your body’s defence system will most likely overwhelm the virus and you will be well again.  Antibiotics are no help at all against a virus. 

Virus

When you have a cold, for example, it is caused by a virus.  Many insist they need antibiotics when they feel sick, but they are not effective against viruses. 

Bacterium

On the other hand, if you have bronchitis or pneumonia, they are caused by a bacterial infection and maybe a result of first having a virus.  They do not typically respond to simple rest and fluids and may require antibiotics to fight off the disease.

Here is a great video to explain just some of the differences between the two and how differently they infect and grow within our bodies to make us sick.

Most at Risk 

Statistics are still not reliable enough, but there are some common denominators with those who contract the virus and then develop a serious case and then die.  Those most at risk, include:

• ·       The aged (especially those older than 60 years)
• ·       Transplant patients
• ·       Chronically ill
• ·       Those with an auto-immune disease
• ·       HIV patients
• ·       High blood pressure
• ·       Lung diseases – COPD Asthma
• ·       Diabetes Mellitus
• ·       Those with other pre-existing conditions

It will take time to refine this list, but if someone is dealing with a serious or chronic condition, their system is already weak and so it makes sense. 

What has proven notable about COVID-19 is that children do not seem to be so vulnerable to the virus.  More data needs to be collected, verified and collated to substantiate this.

Those especially in the ‘firing line’

With that list in mind, it is obvious there are some individuals who are more vulnerable, not for the condition of their health, but because they are more likely to be exposed to those who have COVID-19. 

This is a key reason why protective medical gear must be available for these individuals, such as:

• ·       Health care workers
• ·       Public transportation workers
• ·       First Responders
• ·       Support and administrative staff in hospitals and clinics
• ·       Retail staff
• ·       Press

High-Risk Environments

If you feel unwell, stay home.  If you know you have been exposed to someone who is infected (or was in close contact with someone who has the virus) stay home (call the doctor, clinic or hospital emergency room and follow their directions. 

Being careful of where you go is most important, now.  Remember initial observations seem to indicate that someone can be infected, be spreading the virus to others and yet not show symptoms.  

Avoid, if at all possible, high-risk environments, such as:

• ·       Hospitals, clinics, doctor’s offices
• ·       Universities
• ·       Correction Facilities/Prisons
• ·       Aged Care facilities
• ·       Sports Events
• ·       Conferences
• ·       Large group gatherings
• ·       Government services centres 

Conclusion 

Keep in mind, initial statistics indicate that eighty-one per cent of those who contract the virus will have a mild to very mild form.  

If you suspect you have been exposed to COVID-19, stay home, call your health-care provider and follow their directions.  They will know the best strategy to follow.
