On 31 December 2019, there was an unknown cause that gave rise to pneumonia cases in Wuhan City, China. It was not long until the World Health Organization (WHO) was informed of a new Coronavirus Disease, which is known as COVID-19, until present 2021.
This infectious disease infects human beings, leading to them experiencing mild to moderate respiratory illness and recovering without requiring special treatment.
However, there are cases where elderly and population with underlying medical conditions such as cardiovascular disease, diabetes mellitus, respiratory disease, and cancer are more prone to develop serious symptoms.
Covid-19 has been existing from 2019 until the present day, there have been plenty of questions and doubts regarding this disease. Here are 8 myths and facts about this highly infectious disease that were found to be closely related to our daily life.
1. Can Covid-19 virus be transmitted through goods, cash and groceries?
Yes. Covid viruses can stay on the surface for many hours and up to days. Examples such as metal products can have the virus survive up to 9 days, woods up to 4 days, plastic surface up to 3 days and etc.
Thus, it is better to be safe than sorry. It is strongly suggested to disinfect items’ surfaces and frequently-touched objects using a disinfecting spray or wipe.
As for groceries such as fruits and vegetables, rinsing them in cold water or cleaning with vegetable brushes are adequate. Using disinfecting spray, wipe or soap can lead to possible food poisoning.
2. Are insects such as mosquitoes and houseflies, possibly carriers that spread Covid-19?
Currently there is no evidence that covid viruses can be transmitted through insects. However, proper protection against mosquitoes are still required to protect against disease such as dengue fever, malaria, etc.
3. Is the virus able to stick to our clothes and shoes?
There’s not much research about how long the virus lives on fabric.
The possibility of COVID-19 being spread on shoes and infecting individuals is very low as well. As a safeguard, especially when there are infants and small children crawling or playing on floors, do remove the shoes before entering home.
It is also recommended that proper hygiene needs to be practised, besides from showering every day, clothes should be washed with detergent or soap in 60-90 ⁰C water, drying clothes under a hot sun or in a high temperature dryer can help to kill the virus as well.
4. Can Covid-19 be prevented by rinsing the nasal cavity with saline solution? Besides, is gargling with mouthwash, warm water with salt or vinegar solution proven to prevent viruses and other things to travel into the throat and lung?
Evidence has shown that rinsing the nose with saline solution can help the patient to recover faster from the common cold symptoms, but unable to prevent Covid-19 and other infectious respiratory diseases such as pneumonia.
Moreover, the Centers for Disease Control and Prevention (CDC) suggested that gargling with warm salty water can help with soothing a sore throat, but not effective in stopping infection with Covid-19.
5. Are there any medications that can prevent and cure Covid-19?
There has been news where medications such as oral steroids, hydroxychloroquine, azithromycin and Ivermectin are claimed to be able to treat or prevent Covid-19.
Oral steroids such as Dexamethasone have anti-inflammatory and immunosuppressive effects, which only should be used for Covid-19 patients with severe and critically ill conditions. For some Covid-19 patients on ventilators, a daily 6 mg dose of dexamethasone for 10 days may improve their health.
Dexamethasone provides no improvement for patients with mild symptoms.
As for hydroxychloroquine and azithromycin, randomized clinical trials and studies have been conducted to evaluate the safety and efficacy of these medications.
In conclusion, The COVID-19 Treatment Guidelines Panel does not recommend the use of azithromycin, chloroquine, or hydroxychloroquine for the treatment of COVID-19 in both hospitalised and non-hospitalised patients.
On the other hand, while initial research is still ongoing, FDA has neither approved nor supported the use of ivermectin to treat or to prevent COVID-19.
All in all, currently there is no drug approved that is able to prevent and treat Covid-19 disease and taking a drug for an unapproved use can be very dangerous. Misinformation and misuse of medications can lead to overdose, side effects and contraindications that can be fatal. Patients with covid symptoms should receive proper and supportive care to alleviate the symptoms.
6. Can drinking alcohol or eating garlic help to prevent Covid-19?
Drinking alcoholic beverages, such as wine, beer or liquor doesn’t help to prevent Covid-19. Besides, alcohol is known to harm human health and is associated with a range of diseases. Alcohol can also compromise one’s immune system; increase the risk of adverse health outcomes, leading to the person more vulnerable to Covid virus.
Garlic, though is known to have antimicrobial properties and used in public to prevent disease such as cold, there has been no evidence that it can help to prevent or cure Covid-19.
7. Do UV bulbs, disinfectants such as bleach or chlorine help to kill Covid-19 viruses on our body?
First of all, it does not help with killing the virus inside the body. Besides, do not use UV bulbs, high concentration alcohol or chlorine on your hands or any part of the body because it can irritate your skin, damage body tissues such as eyes and lips.
As advised by the Centers for Disease Control and Prevention (CDC), the best way to prevent the spread of coronavirus and reduce the likelihood of getting infected is by washing our hands with soap and water for at least 20 seconds, especially after going to the bathroom; before and after meals; and after coughing, sneezing, or blowing one’s nose.
If soap and water are not available, alcohol-based hand sanitizer that contains at least 60% alcohol should be used.
8. Do vitamin and mineral supplements contribute to preventing and healing patients from Covid-19?
Micronutrients, such as vitamin B, C, D, E, zinc and magnesium, are important to maintain a well-functioning immune system and play a vital role in promoting health and nutritional well-being.
However, there is currently no guidance on the use of micronutrient supplements as a treatment of COVID-19.
In summary, prevention is better than cure. Always protect yourself by following the standard operation procedure (SOP) such as wear mask properly, stay at least 1m from others, get vaccinated, avoid crowds and unventilated area, practice washing and sanitizing hands often, cover coughs and sneezes with hands, clean and disinfect frequently touched area, monitor your health daily and seek for health professionals if required.
