How does contagion occur?
People can get COVID-19 from contact with another person who is infected with the virus. When an infected person coughs or breathes out, it can be spread by the tiny drops that are released from the nose or mouth. Other people can get VID-19 by touching impregnated objects or surfaces and then touching their eyes, nose, or mouth. They can also get it if they inhale the tiny drops spread by a person with COVID-19 when they cough or breathe out. It is important to stay more than 3 feet away from a sick person..
What are the symptoms?
Flu-like symptoms: fever, cough, shortness of breath, tiredness and muscle aches Breathing problems occur when the infection affects the lungs and causes pneumonia. In most cases, symptoms appear three to seven days after exposure to the virus, although the incubation period can be as long as 14 days.
Are people with diabetes more vulnerable to COVID-19?
People with diabetes are no more at risk than other groups for infection but may be more vulnerable to becoming seriously ill from COVID-19 (just like getting the flu) because their immune system has fewer defenses. Other groups at risk for severe complications are the elderly and those with medical conditions such as high blood pressure and heart disease.
Last March 2020 The Lancet* analyzed data from patients with higher mortality showing increased risk in people with hypertension and diabetes *Fang et Al. The Lancet respiratory https://doi.org/10.1016/S2213-2600(20)30116-8.
Fluctuations in glucose levels compromise the immune system and make the viral infection more difficult to treat.
The virus has a tendency to progress in an environment of high blood glucose. This, coupled with the complications of diabetes, makes it difficult to fight the virus and probably leads to a longer recovery period.
