The current COVID-19 pandemic has thrown the world into disarray since the virus responsible, SARS-CoV-2, was identified late last year. Scientists are continuously learning more about this virus, leading to numerous questions and doubts. Here, we address some of the most frequently asked questions regarding SARS-CoV-2.
1. How Is COVID-19 Transmitted?
How does the new coronavirus (SARS-CoV-2) spread?
This new coronavirus primarily spreads through close contact with an infected person. When someone who has COVID-19 coughs, talks, sings, or sneezes, they release respiratory droplets that contain the virus. If you're within proximity, these droplets can enter your body through your mouth, nose, or even your eyes. Notably, individuals who do not exhibit symptoms can still transmit the virus, making asymptomatic spread a significant factor in the pandemic's transmission dynamics [2]. Additionally, touching a surface contaminated with the virus and then touching your face can also lead to infection. Recent studies have highlighted the role of contaminated surfaces in the spread of SARS-CoV-2, emphasizing the importance of hand hygiene [1].
2. Can COVID-19 Spread via Feces?
Can the new coronavirus spread through fecal matter?
The potential for transmission through feces seems low. While early data indicated that viral particles were found in the feces of infected individuals, it's still uncertain how effectively these particles can cause infection. However, certain studies suggest that fecal shedding of the virus can occur, although its clinical significance remains unclear [5]. It's always a good idea to wash your hands before eating and after using the restroom.
3. Who Is at Higher Risk?
Who might face severe complications from COVID-19?
Current data suggests that older adults and those with underlying health conditions, such as hypertension, diabetes, heart disease, cancer, or respiratory issues, are more likely to experience severe complications if they contract COVID-19. A comprehensive review indicated that these populations are particularly vulnerable to severe outcomes, including hospitalization and mortality [3].
4. Can Antibiotics Treat COVID-19?
Are antibiotics effective against COVID-19?
Since COVID-19 is a viral infection, antibiotics, which are designed to treat bacterial infections, are ineffective. It's crucial to avoid taking antibiotics without a doctor's guidance, as misuse can lead to antibiotic resistance. In fact, during the pandemic, there has been a notable increase in unnecessary antibiotic prescriptions, which raises concerns about the potential for increased antimicrobial resistance [4].
5. Treatments for COVID-19
Are there any medicines or therapies available for COVID-19?
Several medications are currently being used to alleviate symptoms associated with COVID-19, but they do not cure the virus itself. These treatments primarily aim to provide symptom relief while the immune system combats the infection. Ongoing clinical trials are exploring potential cures, and vaccines are being developed. It is essential to remain cautious and refrain from self-medicating, including using herbal or natural remedies, as their efficacy and safety are not guaranteed [1].
6. Coronavirus Transmission
Can the virus be transmitted through the air?
Airborne transmission involves the spread of the virus via droplets (aerosols) that can linger in the air for extended periods and distances. Research has indicated that SARS-CoV-2 can be transmitted through the air during certain medical procedures that generate a lot of aerosols, but the risk of airborne transmission without these procedures is still being debated. Some studies suggest that while aerosol transmission is possible, it may not be the primary route of infection in most community settings [2].
7. The Incubation Period
How long does it take for symptoms to appear after infection?
The incubation period for COVID-19—the time from infection to symptom onset—can range from 1 to 14 days, with most individuals developing symptoms in approximately five days. Understanding the incubation period is crucial for effective tracking and management of the disease, especially in controlling outbreaks [5].
If you have concerns regarding COVID-19 and want to explore your options, you might consider an online doctor consultation. Whether you choose to chat with a doctor or connect with an online AI doctor, there are many ways to get the information you need. So, don't hesitate to talk to a doctor online for personalized advice.
