BACKGROUND: The association between COVID-19 incidence and genetic underlying is an interesting issue. The possible association between thalassemia and COVID-19 is proposed. In additional to beta-thalassemia, alpha-thalassemia is another important group of thalassemic disorder.
MATERIALS AND METHODS: In this report, the authors present an observation on correlation between alpha-thalassemia 1carrier prevalence and incidence of COVID-19 from a tropical country in Southeast Asia that alpha-thalassemia is endemic.
RESULTS: According to this study, there is no significant correlation and the calculated correlation coefficient between alpha-thalassemia carrier prevalence and incidence of COVID-19 is equal to − 0.82 (P > 0.05).
CONCLUSION: According to the current data, there is no discernible link between the incidence of COVID-19 and the prevalence of alpha-thalassemia 1 carriers.
Keywords: Alpha-thalassemia 1, correlation, COVID-19

| Introduction|| |
COVID-19 is an important infection affecting more than 145 million people. The association between COVID-19 incidence and genetic underlying is an interesting issue. The possible association between thalassemia and COVID-19 is proposed., It is observed that there might be a natural resistance of cases with beta-thalassemia against COVID-19., In additional to beta-thalassemia, alpha-thalassemia is another important group of thalassemic disorder.
In this report, the authors present an observation on correlation between alpha-thalassemia 1carrier prevalence and incidence of COVID-19 from a tropical country in Southeast Asia that alpha-thalassemia is endemic. In the study setting, Indochina, there is a very high incidence of thalassemia. The locals from this region have high rates of hemoglobin E, alpha-and beta-thalassemia diseases, and glucose-6-phosphate dehydrogenase deficiency. The local incidence of alpha-thalassemia gene carrier is about 15%–30% of local people., The local epidemiology data shows that there is an extremely high incidence on thalassemia comparing to other areas of the world. An explanation is the long term genetic adaptation to the local high incidence of malaria.
| Materials and Methods|| |
The present study is a clinical mathematical correlation study. The aim is to determine association between alpha-thalassemia 1 carrier prevalence and incidence of COVID-19. The primary data from previous publication on alpha-thalassemia 1 carrier prevalence are used. For data on incidence of COVID-19, public data from Ministry of Public Health (https://covid19.ddc.moph.go.th/) are used.
To assess association, the correlation between alpha-thalassemia 1 carrier prevalence and incidence of COVID-19 in different health regions is calculated. Since the present study is not a study on human or animal subjects, it requires no ethical approval or informed consent.

Primary data are presented in [Table 1]. There is no significant correlation and the calculated correlation coefficient between alpha-thalassemia carrier prevalence and incidence of COVID-19 is equal to − 0.82 (P > 0.05).

| Discussion|| |
One of the most prevalent and significant inherited red blood cell disorders is thalassemia. The prevalence of the illness is really high in our region. Millions of residents were already infected with COVID-19 when the disease first spread to Southeast Asia during the COVID-19 era. It is conceivable for COVID-19 and thalassemia to co-infect. Approximately one-third of all COVID-19 cases in the region with a high incidence of thalassemia also have hemoglobin disorder.
The interrelationship between underlying alpha-thalassemia and COVID-19 is an interesting issue for investigation. For a case with underlying thalassemic disorder, an increased severity of COVID-19 is an issued to be studied. There is a report confirming that there might be coagulation abnormalities due to COVID-19 in a child with thalassemia. Enhanced mortality of-thalassemia heterozygotes from COVID-19 is indicated by a pilot study by Sotiriou et al. On the other hand, the immunopathological process of COVID-19 in a thalassemia case might also be altered. Lansiaux et al. recently reported that immunity against COVID-19 might be clinically related beta-thalassemic heterozygote population prevalence. Resistance to COVID-19 attack might be resulted from abnormal globin chain in hemoglobin in thalassemic patients., In order to cause an ACE/ACE2 imbalance and promote erythropoietin EPO hypersecretion utilizing tissue RAS, uncoupled from hemoglobin levels, the SARS-CoV-2 coronavirus must enter the cell. As their EPO stimulation is decoupled from the RAS system, thalassemia carriers would benefit from protection at any age.
In this work, the authors add an observation from the previous studies on beta-thalassemia. The study on alpha-thalassemia is done. Analysis on the clinical association of alpha-thalassemia is done and reported. Of interest, the present study shows an observation that is discordant with the previous reports on beta-thalassemia,, no resistant nature of alpha-thalassemia 1 carrier to COVID-19. In fact, the earlier publication stated that if infected with COVID-19, a case with an underlying alpha-thalassemia condition could easily evolve into a severe clinical problem. As a result, the actual COVID-19 data in the thalassemia situation may not agree with previously offered hypothetical solutions., In fact, a recent study from Italy, where thalassemia is also extremely prevalent, demonstrated that people with underlying hereditary red blood cell problems, such as thalassemia, are susceptible to developing serious illness. In individuals with an underlying hemoglobin disease, the first asymptomatic COVID-19 instance developed serious clinical issues and required hospitalization. The lack of a link in our study may indicate that there are numerous confounding factors that can alter how SARS-CoV-2 infection manifests in a patient with underlying thalassemia even while there is no direct correlation between the two.
The epidemiology of COVID-19 is distinct and influenced by a variety of factors. The situation changes with time, and it is important to remember the impact local disease control measures have. The concomitant medical condition could impact inflammatory pathways or other pathophysiology aspects of COVID-19., In addition, the pattern of COVID-19 may be impacted by personal medication. The exact interrelationship between thalassemia and COVID-19 is an interesting issue for further studies in clinical hematology. Furthermore, further studies on other common genetic hematological disorders such as hemoglobinopathies are recommended.

Based on the present analysis, no significant correlation between alpha-thalassemia 1 carrier prevalence and incidence of COVID-19 is observed.
