What is Covid 19 and how started
At the end of December 2019, Chinese public health authorities reported several cases of acute respiratory syndrome in Wuhan City, Hubei province, China. Chinese scientists soon identified a novel coronavirus as the main causative agent. The disease is now referred to as coronavirus disease 2019 (COVID-19), and the causative virus is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is a new strain of coronavirus that has not been previously identified in humans.
Coronaviruses are a large family of viruses that are common in people and many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people. This occurred with MERS-CoV and SARS-CoV, and now with the virus that causes COVID-19. The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV. All three of these viruses have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir. However, the exact source of this virus is unknown.
The initial outbreak in Wuhan spread rapidly, affecting other parts of China. Cases were soon detected in several other countries. Outbreaks and clusters of the disease have since been observed in Asia, Europe, Australia, Africa and the Americas.
While animals are believed to be the original source, the virus spread is now from person to person (human-to-human transmission). There is not enough epidemiological information at this time to determine how easily this virus spreads between people, but it is currently estimated that, on average, one infected person will infect between two and three other people.
The virus seems to be transmitted mainly via small respiratory droplets through sneezing, coughing, or when people interact with each other for some time in close proximity (usually less than one meter). These droplets can then be inhaled, or they can land on surfaces that others may come into contact with, who can then get infected when they touch their nose, mouth or eyes. The virus can survive on different surfaces from several hours (copper, cardboard) up to a few days (plastic and stainless steel). However, the amount of viable virus declines over time and may not always be present in sufficient numbers to cause infection.
The incubation period for COVID-19 (i.e. the time between exposure to the virus and onset of symptoms) is currently estimated to be between one and 14 days.
We know that the virus can be transmitted when people who are infected show symptoms such as coughing. There is also some evidence suggesting that transmission can occur from a person that is infected even two days before showing symptoms; however, uncertainties remain about the effect of transmission by asymptomatic persons.
The infectious period may begin one to two days before symptoms appear, but people are likely most infectious during the symptomatic period, even if symptoms are mild and very non-specific. The infectious period is now estimated to last for 7-12 days in moderate cases and up to two weeks on average in severe cases.
Symptoms of COVID-19 vary in severity from having no symptoms at all (being asymptomatic) to having fever, cough, sore throat, general weakness and fatigue and muscular pain and in the most severe cases, severe pneumonia, acute respiratory distress syndrome, sepsis and septic shock, all potentially leading to death. Reports show that clinical deterioration can occur rapidly, often during the second week of disease.
Recently, anosmia – loss of the sense of smell – (and in some cases the loss of the sense of taste) have been reported as a symptom of a COVID-19 infection. There is already evidence from South Korea, China and Italy that patients with confirmed SARS-CoV-2 infection have developed anosmia / hyposmia, in some cases in the absence of any other symptoms.
Most people (about 80%) recover from the disease without needing hospital treatment. Around 1 out of every 5 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart and lung problems, diabetes, or cancer, are at higher risk of developing serious illness. However, anyone can catch COVID-19 and become seriously ill. People of all ages who experience fever and/or cough associated with difficulty breathing/shortness of breath, chest pain/pressure, or loss of speech or movement should seek medical attention immediately. If possible, it is recommended to call the health care provider or facility first, so the patient can be directed to the right clinic.
In order to find out if someone has currently the virus, we can use the polymerase chain reaction (PCR) tests, a molecular diagnostic testing technique that detects the genetic material from the virus and can help diagnose an active COVID-19 infection.
Antibody testing checks a sample of a person’s blood to look for antibodies to SARS-CoV-2, the virus that causes COVID-19. These antibodies are produced when someone has been infected, so a positive result from this test indicates that person was previously infected with the virus.
We do not know yet if the antibodies that result from infection with SARS-CoV-2 can protect someone from reinfection with this virus (immunity) or how long antibodies to the virus will protect someone. Scientists are conducting research to answer those questions.
Antibody tests may not be able to tell you if you are currently infected because it typically takes 1 to 3 weeks to develop antibodies to SARS-CoV-2. To tell if you are currently infected, you would need a test that identifies the virus in samples from your upper respiratory system, such as a nasopharyngeal swab.
There are two broad categories of test: a viral test for a current infection, or an antibody test for the past presence of the virus.
There is no specific treatment or vaccine for this disease. Healthcare providers are mostly using a symptomatic approach, meaning they treat the symptoms rather than target the virus, and provide supportive care (e.g. oxygen therapy, fluid management) for infected persons, which can be highly effective.
In severe and critically ill patients, a number of drugs are being tried to target the virus, but the use of these need to be more carefully assessed in randomized controlled trials. Several clinical trials are ongoing to assess their effectiveness but results are not yet available.
As this is a new virus, no vaccine is currently available. The development of vaccines takes time. Several pharmaceutical companies and research laboratories are working on vaccine candidates. It will, however, take many months or even years before any vaccine can be widely used, as it needs to undergo extensive testing in clinical trials to determine its safety and efficacy. These clinical trials are an essential precursor to regulatory approval and usually take place in three phases. The first, involving a few dozen healthy volunteers, tests the vaccine for safety, monitoring for adverse effects. The second, involving several hundred people, usually in a part of the world badly affected by the disease, looks at how effective the vaccine is in the field, and the third does the same in several thousand people.
How to Protect Yourself & Others
Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing serious complications from COVID-19 illness. Elderly people above 70 years of age and those with underlying health conditions (e.g. hypertension, diabetes, cardiovascular disease, chronic respiratory disease and cancer) are considered to be more at risk of developing severe symptoms. Men in these groups also appear to be at a slightly higher risk than females.
Know how it spreads
- There is currently no vaccine to prevent coronavirus disease 2019 (COVID-19).
- The best way to prevent illness is to avoid being exposed to this virus.
- The virus is thought to spread mainly from person-to-person.
- Between people who are in close contact with one another (within about 2 meter).
- Through respiratory droplets produced when an infected person coughs, sneezes or talks.
- These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
- Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms.
Wash your hands often
- Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place or after blowing your nose, coughing, or sneezing.
- If soap and water are not readily available, use a hand sanitizer that contains at least 70% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
- Avoid touchingyour eyes, nose, and mouth with unwashed hands.
Avoid close contact
- Avoid close contact with people who are sick, even inside your home.If possible, maintain 2 meter between the person who is sick and other household members.
between yourself and other people outside of your home.
- Remember that some people without symptoms may be able to spread virus.
- Stay at least 2 meter (about 2 arms’ length) from other people.
- Do not gather in groups.
- Stay out of crowded places and avoid mass gatherings.
- Keeping distance from others is especially important for people who are at higher risk of getting very sick.
Cover your mouth and nose with a cloth face cover when around others
- You could spread COVID-19 to others even if you do not feel sick.
Everyone should wear a cloth
face cover when they
have to go out in public, for example to the grocery store or to
pick up other necessities.
- Cloth face coverings should not be placed on young children under age 3, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
- The cloth face cover is meant to protect other people in case you are infected.
- Do NOT use a facemask meant for a healthcare worker.
- Continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.
Cover coughs and sneezes
- If you are in a private setting and do not have on your cloth face covering, remember to always cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow.
- Throw used tissues in the trash.
- Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not readily available, clean your hands with a hand sanitizer that contains at least 70% alcohol.
Clean and disinfect
- Clean AND disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.
- If surfaces are dirty, clean them. Use detergent or soap and water prior to disinfection.
- Then, use a household disinfectant.
COVID-19 & children
Based on available evidence, children do not appear to be at higher risk for COVID-19 than adults. While some children and infants have been sick with COVID-19, adults make up most of the known cases to date.
The symptoms of COVID-19 are similar in children and adults. However, children with confirmed COVID-19 have generally presented with mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher risk for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.
You can encourage your child to help stop the spread of COVID-19 by teaching them to do the same things everyone should do to stay healthy:
- Avoid close contact with people who are sick.
- Stay home when you are sick, except to get medical care.
- Cover your coughs and sneezes with a tissue and throw the tissue in the trash.
- Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
- If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 70% alcohol. Always wash hands with soap and water if hands are visibly dirty.
- Clean and disinfect frequently touched surfaces and objects (e.g., tables, countertops, light switches, doorknobs, and cabinet handles).
- Launder items, including washable plush toys, as appropriate and in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry from an ill person can be washed with other people’s items.
Exposing yourself to the sun or to temperatures higher than 25oC degrees DOES NOT prevent the coronavirus disease (COVID-19)
You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19. To protect yourself, make sure you clean your hands frequently and thoroughly and avoid touching your eyes, mouth, and nose.
There are currently no drugs licensed for the treatment or prevention of COVID-19
While several drug trials are ongoing, there is currently no proof that hydroxychloroquine or any other drug can cure or prevent COVID-19. The misuse of hydroxychloroquine can cause serious side effects and illness and even lead to death.
Are antibiotics effective in preventing and treating the new coronavirus?
No, antibiotics do not work against viruses, only bacteria. The new coronavirus (2019-nCoV) is a virus and, therefore, antibiotics should not be used as a means of prevention or treatment. However, if you are hospitalized for the 2019-nCoV, you may receive antibiotics because bacterial co-infection is possible.
The new coronavirus CANNOT be transmitted through mosquito bites.
To date there has been no information or evidence to suggest that the new coronavirus could be transmitted by mosquitoes. The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water. Also, avoid close contact with anyone who is coughing and sneezing.
COVID-19 IS NOT transmitted through houseflies
To date, there is no evidence or information to suggest that the COVID-19 virus transmitted through houseflies. The virus that cause COVID-19 spreads primarily through droplets generated when an infected person coughs, sneezes or speaks. You can also become infected by touching a contaminated surface and then touching your eyes, nose or mouth before washing your hands. To protect yourself, keep at least 2 meters distance from others and disinfect frequently-touched surfaces. Clean your hands thoroughly and often and avoid touching your eyes, mouth and nose.
5G mobile networks DO NOT spread COVID-19
Viruses cannot travel on radio waves/mobile networks. COVID-19 is spreading in many countries that do not have 5G mobile networks. COVID-19 is spread through respiratory droplets when an infected person coughs, sneezes or speaks. People can also be infected by touching a contaminated surface and then their eyes, mouth or nose.
Can regularly rinsing your nose with saline help prevent infection with the new coronavirus?
No. There is no evidence that regularly rinsing the nose with saline has protected people from infection with the new coronavirus.
There is some limited evidence that regularly rinsing nose with saline can help people recover more quickly from the common cold. However, regularly rinsing the nose has not been shown to prevent respiratory infections.
