- Whats is Covid-19
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in December 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic. The first confirmed case of what was then an unknown coronavirus was traced back to November 2019 in Hubei.
- Who is at risk of contracting the disease?
Currently travellers to areas where there is ongoing sustained transmission of COVID-19 including Mainland China (all provinces), Hong Kong, Japan, Republic of Korea, Singapore, Vietnam, Taiwan, Italy and the Islamic Republic of Iran are at greatest risk of infection with COVID-19. Furthermore, the elderly, individuals with co-morbidities and healthcare workers have been found to be at a higher risk of morbidity and mortality associated with the SARS-CoV-2. Please consult the latest guidance for information on which countries are experiencing outbreaks of COVID-19. Information can be accessed at https://www.who.int/emergencies/diseases/novel-coronavirus-2019/situation- reports.
- How long does it take to contract the disease?
The time from exposure to onset of symptoms is typically around five days but may range from two to fourteen days. As of 24 April 2020, more than 2.76 million cases have been reported across 185 countries and territories, resulting in more than 193,000 deaths. More than 760,000 people have recovered.
- How the disease is transmitted:
While the first cases probably involved exposure to an animal source, the virus now seems to be spreading from person-to-person. It is thought to happen mainly via respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory pathogens spread. Thus far the majority of cases have occurred in people with close physical contact to cases and healthcare workers caring for patients with COVID-19.The virus is primarily spread between people during close contact, often via small droplets produced by coughing, sneezing, or talking. The droplets quickly fall on objects or onto surfaces but with certain medical procedures can hang in the air for longer periods. People may also become infected by touching a contaminated surface and then touching their eyes, nose, or mouth. In experimental settings, the virus has shown to survive on surfaces for up to 72 hours. It is most contagious during the first three days after the onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease
- How is the disease diagnosed
COVID-19 is diagnosed by a laboratory test, polymerase chain reaction (PCR) molecular test, on a respiratory tract sample (e.g. sample from nose, throat or chest). For specific guidance on sample collection and transport please visit the NICD’s website: https://www.nicd.ac.za/diseases-a-z-index/covid-19/. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors; however, guidelines do not recommend using it for routine screening.
- What precautionary measures can be taken?
Recommended measures to prevent infection include frequent hand washing, maintaining physical distance from others (especially from those with symptoms), covering coughs and sneezes with a tissue or inner elbow, and keeping unwashed hands away from the face. In addition, the use of a face covering is recommended for those who suspect they have the virus and their caregivers. Recommendations for face covering use by the general public vary, with some authorities recommending against their use, some recommending their use, and others requiring their use. This is notable because currently, there is not enough evidence for or against the use of masks (medical or other) in healthy individuals in the wider community. Also masks purchased by the public may impact availability for health care providers.
- Is it safe to travel?
It has been recommended that travellers should avoid all nonessential travel to areas with ongoing sustained transmission of COVID-19 including Mainland China (all provinces), Hong Kong, Japan, Republic of Korea, Singapore, Vietnam, Taiwan, Italy and the Islamic Republic of Iran. People who travel to China or areas ongoing sustained transmission of COVID-19 should avoid visiting the animal markets (avoid contact with farm or wild animals), products that come from animals (such as uncooked meat) and avoid contact with sick people. Ultimately travel bans have been imposed world wide, this is an attempt to slow the spread of the virus and nothing more, so for the sake of all your loved ones avoid travel whenever possible.
- Is there a cure?
Treatment is supportive (e.g. provide oxygen for patients with shortness of breath or treatment for fever). There is no specific antiviral treatment available. Antibiotics do not treat viral infections. However, antibiotics may be required if a bacterial secondary infection develops. Currently, there is no vaccine or specific antiviral treatment for COVID-19. Management involves the treatment of symptoms, supportive care, isolation, and experimental measures
- Status of the virus?
The World Health Organization (WHO) declared the 2019–20 coronavirus outbreak a Public Health Emergency of International Concern (PHEIC) on 30 January 2020 and a pandemic on 11 March 2020. Local transmission of the disease has occurred in most countries across all six WHO regions.
- What does the virus look like?
The virus has been described as a crown... You can make your own assessment here is a animated photo as well as a realistic one.
- The Most common symptoms are as follows: Symptom %:
Shortness of breath
Muscle pain or joint pain
Nausea or vomiting
- DISCLAIMER: Please note as per community guidelines it is frowned upon to inject bleach and or any other disinfectants in any situation irregardless of who suggested it.
