Why is There No Cure and Treatment for Coronavirus?

Understanding Vaccines as Cure

Currently, the landscape of coronavirus (COVID-19) treatment and prevention has seen significant advancements with the emergence of several vaccines approved for full use. As of the latest updates, there are at least eight vaccines that have been approved and are readily accessible worldwide. These vaccines act as a preventive measure by priming the immune system to recognize and combat the virus. Although these vaccines do not directly cure the disease after infection, they significantly reduce the risk of severe illness, hospitalization, and death. [1]

Antiviral Drugs as a Treatment Option

In addition to vaccines, antiviral drugs play a crucial role in managing the course of the disease. One such drug is Remdesivir, which has been administered to patients with severe COVID-19, showing promising results in reducing hospitalization and mortality. Other antiviral drugs are at various stages of development, each aiming to alter the disease's progression upon initial infection. [2]

Monoclonal Antibodies and Symptomatic Treatment

Moreover, monoclonal antibodies have emerged as a critical tool in the fight against SARS-CoV-2. These antibodies specifically target the virus and help reduce the risk of hospitalization and death. They have been approved for use in several countries and are an important step in the management of severe cases. Additionally, other medications, such as immune system supporting or stimulating agents, and immune system suppressing drugs for later-stage severe cases, continue to be researched and developed. [3]

Guidelines and Treatment Protocols

UpToDate provides comprehensive guidelines on the best practices for treating COVID-19. These guidelines reflect the latest advancements in treatment options and help healthcare professionals make informed decisions. The treatment approach often focuses on managing symptoms and providing supportive care, as the virus continues to evolve with new variants. [4]

Biology and Challenges of Viral Mutations

Understanding the basic biology of viruses is essential to addressing the challenges posed by the coronavirus. A virus is a microorganism that exists in a state that is somewhere between living and non-living. It relies on the host organism to survive and replicate. Outside of a host, a virus is virtually non-living, but once introduced into a living organism, it can cause significant harm. The mutation power of viruses contributes to their unpredictability. Small genetic changes in viruses can lead to significant variations in their properties and reactions. These mutations can be particularly dangerous as they can both change the severity of the disease and the effectiveness of treatments. For instance, a small genetic mutation in humans can lead to conditions like cancer or albinism, but viruses can rapidly adapt and potentially become more lethal over time. [5] With each new variant of the coronavirus appearing in different regions, such as India, Brazil, and Europe, medical teams must continuously adapt their strategies. The primary approach is often to treat symptoms rather than to pursue a definitive cure for each variant. This strategy involves using drugs that target specific symptoms, such as malaria drugs for malaria-like symptoms or paracetamol for fever and pain. [6] Conclusion: While the search for a universally effective cure for COVID-19 continues, it is important to recognize the advancements and alternatives that have been developed. Vaccines, antiviral drugs, monoclonal antibodies, and supportive care are all valuable tools in the battle against the coronavirus. As the virus continues to mutate, the medical community will need to remain agile and adapt to new challenges.
