Several medications are approved by the US FDA or EMA for the treatment of the disease. No cure for the disease is known. The most common treatment is a combination of medication, including antiviral, anti-inflammatory and antimicrobial drugs. A specific type of vaccine or a nucleic acid-based injectable drug has been shown to be effective in animal models. There is urgent need for large-scale, multicenter epidemiological, diagnostic and treatment studies in an appropriate biosafety environment. Vaccines are not available in the USA and they may take up 1 year from the first symptoms to receive a working vaccine. There is a need to develop and produce an oral vaccine in case no treatment options are available.
A wide range of variables and their interactions are considered by the WHO. This includes variables related to the source of infection, the virus replication cycle and other factors such as immune system functioning, and the extent of and speed of viral replication in infected hosts. The full range of the variability of these dynamics of infection as well as the effect of the host response is not accounted for.\n\nA WHO report states that the 'virus may evolve at different rates among different people'.\n\nSince the emergence of SARS in 2001, there have been ongoing concerns about the emergence of SARS-related coronavirus, SARS-CoV‑2, or 2019-nCoV.
In patients with acute infection, fever, dry cough, myalgia, fatigue, and loss of appetite are frequently present. Older individuals (>65 yr) have more dyspnea and dyspnea (shortness of breath) than younger age groups.
Hospitalizations in the United States attributable to coronavirus disease-2019 increased from 28,200 in February-June 2019 to 113,000 in March-August 2019. This represents an average rise in hospital admissions of 16.8%. The rate of inpatient admissions is now similar to levels reported for 2020 to 2021. As we expect these rates to continue to rise, it is important for hospitals to plan for a surge in admissions during the coronavirus epidemic as the number of cases reported from around the world will continue to rise. Hospitals must be able to sustain their care for people, even when they are not staying in their ICU.
The overall treatment effect of remdesivir was not associated with improvement in patient-reported outcomes. In the absence of randomisation, it would be difficult to determine whether this was due to the nature of the study design, confounding or residual effects.
The virus is transmitted through coughs and sneezes; one infected person can infect close quarters on a population of more than 400 million. The incubation period is between 1 and 7 days. The virus is spread quickly and can be deadly.
The initial outbreak of virus from Wuhan, China, began in December 2019, with a significant increase reported in first half of 2020. However, the number of cases of infection in China in late December and early January remain to be low with no fatalities thus far. However, the number of patients continues to be increasing and may exceed the peak of patients, with the total patients exceeded 300,000. The Chinese government has announced a 1-week-long national lockdown to contain the infections, which is a drastic decision on an individual basis. Nevertheless, the Chinese government is taking steps to control the spread, which in time would slow down the contagion rate and reduce some casualties.
At low doses, melatonin does not appear to have any measurable effect on human circadian rhythms. Higher doses of melatonin can alter rhythms significantly in individuals with circadian disorders, however, and is not recommended as a drug for treatment of such disorders.\n
There is no evidence that current measures of disease transmission and mortality are ineffective in slowing the spread of SARS-CoV-2 (2019-nCoV). The best evidence suggests that SARS-CoV-2 infection has a high risk of pneumonia and other conditions that may be hard to diagnose clinically to reduce mortality, but this is uncertain. People are also at risk of developing some autoimmune conditions.
The current data suggest that the coronavirus 229E strain was an initial virus causing infections in the early stage in the epidemic of 2019; however, Huanan Seafood Market was later detected responsible of the increase number of infections. To determine the primary cause of the outbreak, we have applied both epidemiologic analysis methods and mathematical theories to assess the dynamic of virus evolution at different stages and time-scales. Our analyses suggest that both virus strains are the plausible causes of the coronavirus infections, and that the later strain is associated with more severe disease. To further understand the cause of disease outbreaks, it is essential to understand whether the cause of infectious diseases affects the epidemiology of disease.

Melatonin was seen to be somewhat effective in lowering blood pressure. Other common side effects such as headache, fatigue, sedation, or trouble sleeping are not likely to be serious or permanent. Therefore, melatonin is not contraindicated for those with cardiovascular disease. Even though few side effects were reported in this study, patients taking melatonin should continue to pay close attention to these common non-serious side effects.
Recent findings of the study have found that melatonin had a clinically significant and positive effect on influenza and COVID-19 patients both in combination with any other treatment as well as in isolation.
