If there is no test that can diagnose COVID-19 and there has never been an isolate found not its purification, both of which has been admitted by the CDC, then how do you know it was COVID-19?

Graphene oxide toxicity has the same systems as COVID-19. Graphene Oxide (GO) is found in Masks and PCR tests. It is stronger than diamond, has very sharp edges for penetrating through cell membranes, yet flexible. Its electronic properties make it highly sensitive to the absorption of molecules such as carbon monoxide (CO), nitrous oxide (NO), nitrogen dioxide (NO2), and ammonia (NH3). All of these compounds are toxic to humans.

The lungs are a potential entrance for graphene nanoparticles into the human body through airway. The inhaled GO nanosheets can destroy the ultrastructure and biophysical properties of pulmonary surfactant (PS) film, which is the first line of host defense, and emerge their potential toxicity. Read more here. and read about what is called "Protein Corona Effect". Because of the high free surface charge, nanomaterials can easily form “coronas” with proteins in biological systems [163, 164]. The protein corona is suggested to affect the circulation, distribution, clearance and toxicity of nanoparticles. GO has a direct effect on human neurons especially the olfactory and taste neurons.

Here are the symptoms:

• Fatigue
• Shortness of breath or difficulty breathing
• Cough
• Joint pain
• Chest pain
• Memory, concentration or sleep problems
• Muscle pain or headache
• Fast or pounding heartbeat
• Loss of smell or taste
• Depression or anxiety
• Fever
• Dizziness when you stand
• Worsened symptoms after physical or mental activities

Furthermore, the symptoms of graphene oxide poisoning are loss of feeling in the extremities [arms and legs].

• Graphene oxide inside the body causes thrombogenicity, thrombi.

• Graphene oxide inside the body causes blood clotting.

• Graphene oxide inside the body causes post inflammatory syndrome or systemic or multi-organ inflammations.

• Graphene oxide inside the body when it is above the levels of glutathione —which is the body’s natural reserve of antioxidants—, causes alteration of the immune system, collapse of the immune system and cytokine storm.

• Inhaled graphene oxide spreads evenly throughout the alveolar tract and causes bilateral pneumonias.

• Inhaled graphene oxide causes inflammation of the mucous membranes and thus loss of taste and smell, possible loss of taste and smell: anosmia.
  
• In short, graphene oxide behaves exactly like the supposed SARS-CoV-2 of the official version, generating the same symptomatology of severe COVID-19.
  
• When installed at the neuronal level, it causes neurodegeneration or, in other words, neurological COVID-19.

Graphene oxide results in anaphylactic shock, toxic blood clotting, fatal lung paralysis, mitochondrial cancer, and endothelial cancer, due to the proliferation of spike proteins and prions with each jab. 

I believe there is no COVID-19, but rather it is a bio-chemical weapon, in which GO nanotubes are used as a protective skin (body armor) for parasites to enter the human body through the respiratory system and has the ability to perforate cell membrane walls to infect the cells with parasites. This is why HCQ, Ivermectin, Zinc, and other anti-parasite medicines work.
