Coronavirus disease Covid-19 Vs Ebola Virus impact on Human History

Coronavirus disease has caused the deaths of thousands of children across the world over the past 30 years. In 2001, the World Health Organization estimated that about 25,000 children died from the disease worldwide that year alone. This figure was revised upwards in 2008 to 80,000 deaths annually.

These figures have been studied extensively, with much of the empirical information being focused on Ebola virus disease (EVD), which had risen to epidemic levels before the emergence of effective treatments.

Coronavirus disease is often considered an example of an emerging disease with high morbidity and mortality, despite occurring in low numbers.

However, aside from a few isolated cases with acute illnesses, the virus does not transmit easily or produce high levels of morbidity and mortality, and most coronavirus cases are asymptomatic.

It is a severe respiratory illness that often results in severe pneumonia in a matter of weeks for those who have underlying illnesses, such as asthma or chronic pulmonary disease.

Those with a viral respiratory infection usually have similar viral complications, such as bronchiolitis. In 2021 Covid-19 situation is worse than ever, and people need to know How Does An Oxygen Concentrator works and its functions.

The main differentiator of coronavirus disease compared to the more well-known Ebola virus disease is the mechanism by which it affects the patient.

The differential diagnosis is important, particularly for cases of acute illness or severe acute respiratory illness that do not fully display the clinical symptoms of EVD, which are severe hemorrhagic manifestations and disseminated infection.

At a broader level, this includes patients with an acute febrile illness that may not fully meet the clinical criteria of Ebola virus disease. This is typically due to elevated serum concentrations of antigens in infectious coronaviruses, which may be established through serological tests.

Certain clinical changes can also be observed in cases of severe acute respiratory illness that do not display the required clinical symptoms of EVD, including fatal exacerbations, prolonged hospitalization, and bacterial infection.

Additionally, the severe acute respiratory illness can occur more frequently in patients who have had a prior viral infection and have been taking antivirals for a while.

Interestingly, some studies have found that if a patient develops a secondary bacterial infection with an unrelated cause such as influenza, the coronavirus can be used to differentiate them from EVD patients, regardless of the presence of clinical symptoms of EVD.

The key difference of coronavirus disease is the diagnosis of the cause of disease, in that a patient would need to have an acute respiratory illness that has been caused by a viral infection.

However, in cases of mild acute respiratory illness, the diagnosis is very straightforward and does not require a clinical diagnosis, as those are characterized by a normal bacterial infection with an associated upper respiratory illness.

The possibility of self-infection by a coronavirus is extremely low in these cases, as all patients have developed the viral infection before their symptoms appeared, and do not possess symptoms of any infection at all.

Coronaviruses can be classified into different groups based on the molecules that are their basis of genetic replication. Group 1 viruses have been investigated as being present only in birds and show no effect in humans, while group 2, 3, and 4 viruses have been shown to show a pathogenic effect on humans.

In group 2, coronavirus A (CHIKV) and coronavirus B (CHIKV2), the viral RNA is complex with ribonucleic acid (RNA) molecules from enteric bacteria and humans.

In this group, there have been a small number of epidemiological studies on coronavirus A and B infection in humans and laboratory models. However, coronavirus A has not been associated with severe disease, while coronavirus B has.

In group 4, coronavirus C (COR1) is capable of cross-reacting with human antiviral serotypes such as flucytosine (FLU) or kanamycin. Coronaviruses with low mortality, such as COR1, seem to be responsible for small outbreaks.

This could also explain why some coronavirus outbreaks have occurred in large groups of people and have not resulted in an epidemic. Moreover, coronavirus infections occur in specific settings, such as hospitals and clinics, which may explain some of the rarity of outbreaks such as in the UK.

This is in line with an article published in April 2014 that discusses epidemiological studies on coronaviruses associated with various hospital outbreaks. Another study has discussed the interaction of coronaviruses and bacterial viruses and whether or not an infectious coronavirus infection can initiate an outbreak.

Interestingly, in a case-control study conducted in the same study, these data revealed that a coronavirus infection could be a source of the primary infection in the event of bacterial infection. When patients were screened for a specific clinical illness (sore throat, cough, and fever), they were all diagnosed with coronavirus infection.

However, when the samples were subsequently tested for human coronavirus infections, only 28% of the cases tested positive. Coronavirus B appears to be a very effective source of viral infection in patients with an underlying illness.

Another case-control study in September 2014 showed that among 751 patients who were infected with human coronavirus infection, 24.6% had a history of staphylococcal infection, 19.9% had an upper respiratory infection, 14.5% had infectious mononucleosis, and 8.6% had an upper respiratory infection resulting in pneumonia.

All patients who had pneumonia had an underlying respiratory infection. Overall, more than 90% of these patients had an existing viral infection with a high viral reservoir. Of those who had pneumonia, 57% had an underlying viral infection.

The findings suggest that this is a reservoir effect, as these coronavirus infections are closely linked to increased susceptibility to respiratory illness. In 2013, around 30 people with cough and fever developed symptoms of acute respiratory illness, most of which had a case history of acute bronchitis or pneumonia.
