Coronavirus / Covid-19 Frequently Asked Questions (FAQ)

Why Coronavirus (Covid-19) quarantine is 14 days?

The incubation time depends on the virus. Symptoms also appear at different rates from person to person. Health authorities, from the World Health Organization (WHO) to the U.S. Centers for Disease Control and Prevention (CDC), are using data from the virus’ incubation period to guide quarantine periods 5 days. Additionally, about 97% of people infected with the virus develop symptoms within 11 days. This means that most people infected with the new coronavirus will show symptoms within 11 days. By providing a 14-day quarantine period, authorities are giving more time to prevent people from getting the virus and others from getting it.

Why Coronavirus (Sars-CoV-2) named as Covid-19?

The new virus “coronavirus category 2 severe acute respiratory syndrome (SARS-CoV-2)”. The name was chosen because the virus is genetically related to the coronavirus that caused the 2003 SARS outbreak. These two viruses are related but different. Covid-19 is more severe than SARS.

Why Covid-19 Patients need Oxygen?

SARS-CoV-2 virus causes COVID-19 pneumonia and hypoxemia. Hypoxemia is a condition in which the blood lacks oxygen. It is a major complication of COVID-19 pneumonia and a leading cause of death. Although some antiviral drugs have been shown to be effective in treating COVID-19 infection, oxygen relieves hypoxemia in severe pneumonia. This can cause an infection and give the lungs time to recover. Oxygen is the savior for many people with COVID-19.

Why Covid-19 is called a Pandemic?

The WHO did not use the word “pandemic” lightly or haphazardly. Because misuse can cause undue fear. Previously, COVID-19 was described as a pandemic. While a pandemic term is related to common disease that occurs in a particular community or region, a pandemic means a global spread of a new disease. At the beginning of the pandemic, Covid-19 was classified as a epidemic mainly confined to China, but it became a pandemic (global pandemic) as it spread to other regions.

Why Covid-19 affects Taste and Smell?

Although the exact cause of olfactory dysfunction is not fully understood, the most likely cause is damage to the cells that support olfactory neurons, called Sertoli cells. These cells can be regenerated from stem cells, which may explain why the smell recovers quickly in most cases.

Why covid-19 causes blood clots?

One theory is that when the new coronavirus attacks vascular endothelial cells, blood clotting occurs. The virus accomplishes this by binding to the ACE2 receptor present on the endothelial cell membrane. Once the virus binds to these receptors, blood vessels begin to release proteins that trigger blood clotting.

Another theory is that COVID-19 will cause the body’s immune system. The system triggers an overactive inflammatory response. This inflammation can cause blood clotting.

Why Covid-19 even after Vaccination?

A small percentage of people who are fully vaccinated against COVID-19 will still get COVID-19 disease. The COVID-19 vaccine is effective. However, if you are exposed to the virus that causes COVID-19, These are called ‘‘vaccine breakthrough cases’’. But in this case patient condition will not much severe, and can recover soon,.

Why covid-19 doesn’t affect babies?

One theory is that children’s immune system is very young and It’s not produce the very radical immune response known as cytokine storms that are formed when adults are infected with the virus. It is this strong response to the virus that helps to cause permanent damage to the lungs and other organ systems, usually irreversible damage to adult patients.

Why covid-19 Symptoms come and goes?

Is coronavirus symptoms appearing or disappearing? yes I agree. Because during the recovery process, people with COVID-19 may experience repeated symptoms of improving menstruation, Fever, malaise, and shortness of breath may occur intermittently for days or weeks.

Why Covid-19 gives Diarrhea?

The virus that causes COVID-19 can enter the gastrointestinal tract through cell surface receptors for an enzyme called angiotensin converting enzyme 2 (ACE2). Receptors for this enzyme are 100 times more common in the gastrointestinal tract than in the respiratory tract.

Why Covid-19 Fever increases at Night?

The main reason is our immune system. Just like our sleep schedule, our immune system has its own resting rhythm. When immune cells are most active and inactive, they protect us during the day, but at night they accumulate and become less active. Some anti-inflammatory drugs that intentionally raise body temperature to kill bacteria. Doctors call this a “transient fever” to fight the infection.

Why Covid-19 has so many Variants?

Viruses are constantly evolving and because of mutation its create new types of virus variants. This type usually does not affect the behavior of the virus. But sometimes It has act differently.

How many Variants of Covid-19?

Now a days, According to WHO, there are lot’s of variants of covid-19 but four types of variants, that are more concerned, which are Alpha, Beta, Gamma, Delta. Other variants are Epsilon, Zeta, Eta, Theta, Iota, Kappa.

Why Covid-19 patients are given Steroids?

Steroids can save the lives of people with severe COVID-19 infection. The steroids used for COVID-19 are dexamethasone, methamphetamine/prednisolone. People with severe COVID-19 are “lungs and systemic inflammation that can affect multiple organs.” May cause a reaction. The powerful anti-inflammatory effects of steroids can offset the harmful effects. 

Why Covid-19 Symptoms vary?

People experience a variety of symptoms. The list is endless, but the most common symptoms are similar. In this context of confusion and conflict, it’s important to look at the more classic symptoms of COVID-19 to identify the virus early. The most common symptoms of coronavirus are: – Fever – Dry cough – Sore throat – Runny nose and stuffy nose – Chest pain and shortness of breath – Fatigue – Gastrointestinal infections – Loss of smell and taste.

Why Coronavirus is more Dangerous for Asthma Patients?

The COVID-19 virus can be a problem for people with asthma. It is important to know that people with asthma are not at risk of contracting the coronavirus. However, people with asthma should take special precautions to protect themselves from the virus, such as washing their hands and staying away from sick people.

Symptoms of COVID-19 are more severe and can worsen outcomes for people with asthma. People with asthma need to keep taking prescription medications to prevent their asthma from getting worse. And covid affects mainly on lungs or asthma patients have already breathing problem. That’s why it can be worse for asthma patient.

Why Coronavirus can be more Dangerous for Diabetic Patients?

People with diabetes develop a condition called diabetic ketoacidosis, usually due to a viral infection. This condition makes it difficult for people with diabetes to control fluid intake and electrolyte levels, which can lead to sepsis.

If you are sick, check for signs of high ketones regularly. Elevated ketone levels can be a sign of high blood sugar. Swallowing liquids and food can be difficult. So, store a variety of foods and drinks, such as sodas. Losing carbohydrates and water during illness can alter blood sugar levels. Check your blood sugar more often than usual during illness to monitor blood sugar fluctuations.

Are Pregnant Women at Higher Risk from Coronavirus?

Pregnant women no longer appear to be vulnerable to SARS-CoV-2, the virus that causes COVID-19. However, research shows that women of the same age are at a higher risk of contracting COVID-19 if they are infected. COVID-19 has also been linked to an increased risk of premature birth during pregnancy.

Older adults, overweight, or pregnant women with a history of high blood pressure or diabetes are particularly at risk of serious consequences from COVID-19. It is important for pregnant women and those around them to take precautions to protect themselves from COVID-19. If you develop an illness (especially fever, cough, shortness of breath), seek medical attention immediately.

Why Covid-19 recovered Patients getting Black Fungus?

Mucormycosis fungi can develop at any time after a COVID-19 infection, whether in the hospital or within a few days to two weeks after discharge. It inadvertently stimulates the growth of mold. COVID-19 damages the mucous membranes and blood vessels of the airways. It also increases iron levels in the blood, which is very important for fungal growth.

Drugs such as steroids raise blood sugar levels. Popular antibiotics not only kill pathogens, but also protect against dandruff. Antifungal drugs like voriconazole prevent aspergillosis, but Mucor is unhealthy and thrives when uncompetitive. Prolonged ventilation weakens immunity and mold can be carried by oxygen through humidifiers. These are all ideal recipes for fungal mucosal infections.

Why Covid-19 recovered Patients cannot take Vaccine and till how much Time?

This is based on a recommendation from the National COVID-19 Vaccine Management Group (NEGVAC) to delay immunizing patients with COVID-19. The team also recommended delaying vaccination for three months in patients who received antibody or plasma therapy for virus deficiency.

Do Animals also affect from Coronavirus?

Some pets around the world, including cats and dogs, have been reported to be infected with the external sign of the COVID-19 virus after close contact with people infected with COVID-19. Animals that infect humans with COVID-19 are rare, and the virus that causes COVID-19 can be transmitted from person to person under certain circumstances, often through close contact with pets.

Why Sanitizer use to Prevent coronavirus?

Hand sanitizer can help prevent the spread of bacteria through your hands and it kill the germs. The envelope virus is also effective against the novel coronavirus. Alcohol-based hand sanitizers are effective at killing these enveloped viruses by breaking the lining and making it non-infectious.

Can a COVID-19 Positive Mother transmit Virus in a new Born Baby through Breastfeeding?

The virus has been found in breast milk in a small number of studies. In a study of mothers with SARS-like coronavirus (SARS), no SARS virus was detected in breast milk. Early research suggests that mothers of the new coronavirus have strong immune systems and strong responses to secretions.

Immunoglobulin (A). IgA is the primary antibody found in nursing mothers, when their babies are converted into breast milk. Immunoglobulin A covers your baby’s mouth, respiratory tract, external auditory canal and intestines and prevents the build-up of bacteria and viruses. So yes, we can say that viruses are not spread by breastfeeding.
