An expert, Dr. Bruce Aylward, from the World Health Organization, is of a similar mind. But there is hope for stemming the spread now.

Patients who have “recovered” from the virus produce antibodies in their blood plasma. These antibodies may protect them from further infection and can be used as a treatment for other current patients. But this, also, is questionable.

If the antibodies provide any protection, they might be a stop-gap measure before the availability of a vaccine. How long will that protection last before a viable treatment is devised?

Vaccines currently in clinical trials around the world may be one response to stave off contracting the virus, but not everyone will be vaccinated. The lack of total world immunization will result in clusters of either asymptomatic or symptomatic individuals spreading the disease in unprotected areas. Then, too, no one knows if the vaccines will work or how long their effectiveness will last.

To extinguish an ongoing epidemic and obviate the need for any other measures (e.g., social distancing), the vaccine has to have an efficacy of at least 80% with a 75% vaccine coverage.

As vaccines become available and are introduced into world populations, those who have had COVID19 may not benefit from them. Cleared and identified as recovered, these patients are now exhibiting a wide-ranging array of previously unknown symptoms. Could a vaccine negate these symptoms in a patient now recovered? Are the symptoms permanent?

Unusual, long-lasting or transient symptoms

The lungs were thought to be the primary area of attack of the virus, but it soon became apparent that there were other, unusual and unnoticed, manifestations of the disease. Only now is the medical community coming to grips with a virus that appears to come in more than one form and with new symptoms.

COVID19 attacks the entire body in its process that affects all the organs in the body in its mechanism causing blood clotting.

Scientists think these clotting complications may stem from the virus’s attack on cells that line the blood vessels. When the virus attacks blood vessel cells, inflammation increases, and blood begins to form clots, big and small. These blood clots can travel all over the body and wreak havoc on organs, perpetuating a vicious cycle of thromboinflammation.

Skin Changes

In Spain, a study of patients found “…skin manifestations in 18 patients in Italy with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, or coronavirus disease 2019 (COVID-19), describing “erythematous rash,” “widespread urticaria,” and “chickenpox-like vesicles.”

Rashes, known as COVID toes, presented as discolorations of pink or purple, developed toward the ends of patients’ toes. As they began to appear, they were a further sign of the virus’ encroachment on parts of the body unassociated with the lungs.

Dr. Sarah Young of The Cleveland Clinic noted, “The symptoms of COVID-19 are evolving, but do not yet include rash. At this point, when we see rashes in patients, we should still follow the standard protocol to determine — based on symptoms, risk factors and exposures — if screening for COVID-19 is appropriate.”

Hair Loss Is Noted

The link between hair loss and COVID is just starting to be reported and recognized in research. Sara Hogan, MD, a health sciences clinical instructor at the David Geffen School of Medicine at UCLA, says this timeline makes sense because hair loss often happens to patients 3 to 5 months after a stressful illness or experience.

Heart Damage

The circulatory system and the heart show damage caused by COVID19. In the heart, one study found “our findings reveal that significant cardiac involvement occurs independently of the severity of original presentation and persists beyond the period of acute presentation, with no significant trend toward reduction of imaging or serological findings during the recovery period.”

Initial symptoms of COVID19 may not include lung issues but “evidence of myocardial injury in 20–40% of hospitalized cases manifesting as cardiac chest pain, fulminant heart failure, cardiac arrhythmias, and cardiac death. Indeed, symptoms of cardiac chest pain and palpitations are the presenting features in some patients.”

Abnormal blood clotting was also noted. The clots can cause stroke, psychosis, and a dementia-like condition. Usually occurring elsewhere in the body, the clots travel to the lung, causing death. In covid19, this wasn’t the case.

So it’s not the pulmonary embolism which is the major cause of severe illness but the inflammation of the blood vessels and a change in the clotting system of the blood.

The Long-Term Effects Now Known

The litany of symptoms associated with COVID19 may still require additions, but we do know that damage is in the whole body. The lungs may be cratered and require transplants, but other symptoms may not be as apparent at this time.

COVID19 also perpetuated its damage via neurologic and psychiatric syndromes. “Altered mental status was the second most common presentation, comprising encephalopathy or encephalitis and primary psychiatric diagnoses, often occurring in younger patients.” Symptoms included psychosis, delirium, visual hallucinations, and peripheral nerve damage.

An additional concern has now cropped us, known as the “post-COVID19 syndrome,” concern has been expressed by Dr. Fauci. The symptoms in many of these unrecovered patients are “highly suggestive” of myalgic encephalomyelitis, the disabling illness also commonly called chronic fatigue syndrome or ME/CFS. “This is something we really need to seriously look at,” said Fauci.

The appearance of some of these symptoms as a result of COVID19 isn’t new. After the 1918 influenza pandemic, approximately one million people were diagnosed with a brain disorder called encephalitis lethargica or “sleepy sickness.” It was seen again in the 20s and 30s.

The cohort of worldwide patients recovering or being reinfected with the virus is growing, and new symptoms will crop up. The task now is to recognize neurologic and psychiatric disorders related to COVID19 and take appropriate measures. But the question of what are “appropriate measures” remains to be answered with trial-and-error efforts against a quickly morphing disease.
