Coronaviruses (Cov) are a family of viruses that cause more serious illnesses from the common cold, such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). As a result of comprehensive researches, it has been revealed that SARS-CoV is transmitted from musk cats and MERS-CoV from single humped camels to humans. There are many coronoviruses types that have not been transmitted to humans yet, but are detected in animals  .
The factors that cause flu are Influenza A and Influenza B viruses. It is the Influenza A virus that causes common disease in humans. Influenza A virus causes disease in humans and animals like pigs, birds and horses; influenza B only in humans. There are also subtypes of influenza A virus that causes disease only in animals. The best known example of this is bird flu. This virus has been shown to be also transmitted to humans in recent years .
Covid-19 falls under the category of “epidemic” disease. The effect of the climate in Wuhan on the spread of Covid-19 can be understood using Traditional Chinese Medicine theories. Chinese medicine academia and many Chinese medicine researchers consider that the cold and dampness, disrupting especially the yang qi, caused by the constant rainy and abnormal hot climate in Wuhan in December 2019, and, paved the way for the epidemic. Patients were mostly affected by dampness-cold pathogens that affect lung and spleen  .
If we approach Covid-19 viral infection in terms of Traditional Medicine Diagnoses    ;
1) Wind-Cold Syndrome (Early period-1)
2) Damp-Cold Syndrome (Early period-2)
3) Heat Attacking the Lung (Intermediate period-1)
4) Damp-Heat Attacking the Lung (Intermediate period-2)
5) Blockage in Lung and visceral organs (Severe period-Intensive care unit)
6) Qi deficiency in Lung and Spleen (Recovery period)
However recently, the prophylactic approach that is the preventive approach before the disease occurs has come to the fore especially in risky groups . In the Covid-19 pandemic, the preventively prophylactic approach becomes even more important, as in the risky groups there are doctors, nurses, healthcare professionals and public officials in charge during this period.
2.1. Prophylaxis in Covid-19 Treatment
1) Due to contamination over the eyes, mouth and nasal mucosa  , local acupuncture points related to these structures, around the nose, Bitong, LI 20 and Yintang, around the mouth, ST 4, DU 26 and around the eye, ST 1, UB 2 useable . Using these points, by pricking the needle, in these contamination areas, creating microinflammation, cytokines such as TGF-α, TGF-β released from platelets in these regions, attract neutrophils to the region. During this period, we see that tissue macrophages are also active. After a while, it activates in other immune cells throughout the body. So when there is a viral infection in these areas, immune cells are ready to respond .
2) Respiratory transmission and initial exposure tonsilla, pharynx, trachea and owing to then it is in the lungs, we use the Yuan (Source) point LU 9 and Luo-connecting point LU 7 of the lung meridian.
3) Immunomodulatory points, LI4, ST36, SP6, REN 12, REN 6 points are used .
Purpose of acupuncture application in the medical observation stage; Motivating the antipathogenic qi of the human body, the functions of the lung and spleen and to distribute epidemic pathogens to strengthen the defense capacity of internal organs . It has been reported in recent studies that the application to ST 36 acupuncture point with anti-inflammatory and anti-allergic properties is the most commonly used acupuncture point for immunomodulation . Many studies provide evidence suggesting that acupuncture application to LI 4, SP 6 and REN 6 points, especially ST 36, causes a significant increase in natural killer (NK) cell activity . In a controlled laboratory experiment, Hubei Chinese Medicine University researchers discovered that acupuncture point ST 36 (Zusanli) electroacupuncture stimulation “increases the level of immune cytokines and spleen CD4 + T cells through TRPV channels”. Findings are important because CD4 + T cells are very important in human immune systems. These cells are called helper T cells and are active in the immune system’s defense against microorganisms, including viruses. CD4 + T cells are capable of differentiating into many different cell subsets in activating the body’s immune system cells, immunoregulation and cytotoxic defense mechanisms. Application to ST 36 acupuncture point is effective in activating the immune system .
A large amount of porphyrin is needed for the virus to survive. New coronavirus attacks hemoglobin in erythrocytes and exposes porphyrin. Based on low levels of heme in coronavirus patients; It is considered that the virus binds directly with human hemoglobin. Porphyrin is an important material for heme synthesis. It is thought that the virus may be competing with iron for porphyrin as the cause of iron increase in the body . Considering this physiopathology, we can add the Sp 10 (Sea of Blood) point used in Heat in the Blood syndrome to prophylaxis in blood related problems .
2.2. Covid-19 Treatment Stages
1) Wind-Cold Sendrome 
Clinical Findings: Heat (mostly low-grade fever), feeling uncomfortable with cold, chills, headache, discomfort from the throat, pain in the muscles.
Tongue Findings: Pale, coating is white and thin.

For Lung Strengthening (Tonification); LU 9, LU 7, UB 13.
To Inactivate Damp; ST 36, ST 40, SP 9.
3) Heat Attacking the Lung

5) Blockage-Collapse in the Lungs and Visceral Organs  [Patient Group to be treated in intensive care]*
Clinical Findings: Very severe breathlessness and as a result a feeling of suffocation, wheezing, increased breathing frequency (These patients can only maintain their breathing with a respiratory support device).
Tongue Findings; Dark purplish tongue, yellow dry tongue coating or thick and oily yellow coating.
Pulse Findings; Rapid and slippery pulse.
Urine: Red colored urine (erythrocytes in the urine).
*Treatment Strategy: In this period, we do not think that acupuncture will be effective because the patients are connected to the respiratory device and the lungs are under the control of the device.
Note: Radiological findings of this period in current medicine, tomography shows glass opacity in more than one large area in both lungs.
6) Lung and Spleen Qi Deficiency   [Recovery Period]

For Lung Strengthening (Tonification); LU 9, LU 7, UB 13.
Strengthening the Spleen; ST 36, ST 40, SP 9.
There is no specific antiviral therapy or vaccine for Covid-19. Studies on this subject continue. Clinical treatment of Covid-19 has so far been limited to support and palliative care. Also, Covid-19 mutated and virulence potent, a new virus can cause a pandemic again. Therefore, immunomodulation has gained importance in prophylaxis that we will perform with acupuncture application.
Acupuncture application, in the light of the many literatures we have read on this subject, especially prophylaxis, effective in the initial stages of Wind-Cold Syndrome, Damp-Cold Affecting the Lung and Lung and Spleen Qi Deficiency (Recovery Period) syndromes; Heat Attacking the Lung, Damp-Heat Affecting Lung syndromes will contribute to plants, medicines and other treatments. In the Lung and Visceral Organs Blockage-Collapse, this treatment will need to be done in intensive care, we think that acupuncture application will not be necessary.
