Diabetes Are More Vulnerable To COVID-19. Why? There are many coronaviruses, ranging from the common cold to much more serious viruses such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). They are viruses that have been transmitted from animals to people. Common signs are typical flu-like symptoms: A fever, cough, breathing difficulties, tiredness and muscle aches. Symptoms usually start within 3-7 days of exposure to the virus, but in some cases it has taken up to 14 days for symptoms to appear. The majority of people who have caught the virus have not needed to be hospitalised for supportive care. However, in up to 15% of cases COVID-19 has been severe and in around 5% of cases it has led to critical illness. The vast majority (around 98%) of people infected to date have survived. Older people and people with pre-existing medical conditions (such as diabetes, heart disease and asthma) appear to be more vulnerable to becoming severely ill with the COVID-19 virus. When people with diabetes develop a viral infection, it can be harder to treat due to fluctuations in blood glucose levels and, possibly, the presence of diabetes complications. There appear to be two reasons for this 1. Firstly, the immune system is compromised, making it harder to fight the virus and likely leading to a longer recovery period. 2. Secondly, the virus may thrive in an environment of elevated blood glucose. Like any other respiratory disease, COVID-19 is spread through air-droplets that are dispersed when an infected person talks, sneezes or coughs. The virus can survive from a few hours up to a few days depending on the environmental conditions. It can be spread through close contact with an infected person or by contact with air droplets in the environment (on a surface for example) and then touching the mouth or nose (hence the common advice circulating on hand hygiene and social distancing). IDF has joined a global effort, together with the world’s leading diabetes organizations, to reduce risk for people with diabetes during the COVID-19 pandemic.



Dear Dr Prashant, Wonderful narration about Diabetes & COVID19 especially it is T2DM. COVID19 has high Morbidity and Mortality in patients suffering from other comorbidities like Diabetes HTN CVD CLD Br Asthma COPD/COAD/COLD (All are one and same) Smokers CRF Malignancy On Radiotherapy On Chemotherapy Immunocompromised patients like who are on Steroids like Rheumatoid Arthritis Ankylosing Spondylitis. Per Se Diabetes is considered to be Immunocompromised state. Any microbes like Bacteria Viruses Fungi thrive well in Glucose laiden tissues. Only way to prevent is meticulous Glycemic control. Recently there was an article published in Cell Metabolism April, 2020 saying that the data taken from Wuhan and COVID19 Well controlled T2DM had very good outcomes and poorly controlled T2DM had worst outcomes including more number of Deaths. Regards and thanks, Dr Sepuri Krishna Mohan.

Informative and educative post. Few more comorbadities with covid19 are there as described by Dr Se puri krishna mohan. It is observation that pts suffering from chronic illness has lower immunity and more prone to a long morbidity and mortality. Conclusion is to early too to associate , generally statics are more accurate and conclusive after disease effects is over. You are right in pointing out the above written statement.

Thanks a lot dear Dr Ashok Leel for your kind words

Useful and informative

To add Dr. Mohan's view--The SARS-COVID 2 Virus has strong affinity to alter HbA1C functioning mechanism in Diabetes causing it severely uncontrolled at the onset of Viral attack!--Dr. Santanu Bhattacharya.
