How to prevent coronavirus infection simply and effectively?

I would like to translate the coronavirus prevention method of the doctors at Cho Ray Vietnam Hospital. It is effective and very easy to implement.

Like the other viruses that cause respiratory infections, SASR-COV-19 has the following mechanism of infection and disease:

I. After entering the pharynx area, the virus will penetrate into the mucosa cells and multiply, from one animal will produce hundreds. Growing large enough in number and structure, they will break down the cell to spread out and each will find its way into a new cell. Just like that the cycle of drug development repeats many times and goes deeper into the body. This stage is the incubation period.

II. At some point (depending on the health of each person) a sufficiently large number of viruses to break down the human defense mechanism, the disease will emerge. This is the onset of the disease.

Thus, during the incubation period, the person carrying the virus has no symptoms so others cannot know. Therefore they have the ability to silently spread the virus to others.

To prevent infection (or spread to others) we must try to prevent the virus from entering our own oropharynx. These are methods to avoid gathering in crowded places, standing far away from suspected people who are infected with more than 2m, wearing a mask (any type), washing our hands often …

However, my own experience has a last block in case those measures are ignored. This is a very important blocking button, although it has been mentioned, but maybe the implementation is not correct and sufficient.

The last stopper is contacting the throat with an antiseptic solution. Once the virus has broken through the aforementioned “firewalls,” the throat antiseptic solution will be available to destroy it. And when the virus after multiplying breaks the cell out, the disinfectant solution is also waiting to destroy it.

Thus, both uninfected and infected people, the throat antiseptic solution will be the last solution to prevent infection as well as spread the disease.

The use of antiseptic solutions in the oropharynx to rinse your mouth also needs to be properly effective. There are some types of disinfectant that can kill the virus, but there are others. And each type of disinfectant has the ability to kill viruses in different time periods, some lasts 1-2 hours after contact but there are types that can last more than 4 hours. Please pay close attention to the manufacturer’s instructions. However, there are some basic principles:

  • To rinse the throat, not the mouth. This means trying to get the solution down to the deepest part of your throat.
  • Do not need too much in one contact, about 5ml is enough. The more you have, the harder it is to bring the solution down to the throat.
  • Rinse your throat before going out, and as soon as you come home (or as close contact with others). If on the plane, you should contact every 3 hours (with chlohexidin) or immediately after eating.
  • In the epidemic area, rinse mouth periodically according to the time of effect of each solution.
  • Do not be subjective in thinking that this last protective stopper can replace other measures. The effectiveness of disease prevention is the coordination of all.

Notice how to rinse your mouth:

• Approximately 2 minutes at a time, including three to the throat approximately 15 seconds each time.

• After finishing washing, do not rinse with water.

Which SSL do I need?

Some websites or server configurations require a specific type of SSL. Use these questions as a guideline to help determine which SSL you should use.

Which SSL do I need?
SSL Certificates

Is this for a business or a personal website?

How do you want to show visitors that your site is secure? Do you want visitors to see the SSL belongs to a verified organization, or is HTTPS in the address enough?

All SSL-secured sites display HTTPS in the address. Premium Extended Validation (EV) SSLs also display a prominent indicator — usually a green address bar — to quickly assure visitors that the organization’s legal and physical existence was verified according to strict industry standards. For more information, see What is a Premium Extended Validation (EV) SSL certificate?

How many unique domains do you want to secure with HTTPS?

Do all of the sites have fully qualified domain names, or do you need to add a few subdomains (see What is a subdomain?) on the fly?

  • Single-domain SSLs cover one domain or subdomain. For example, you can secure You can purchase single-domain SSL’s as Standard, Deluxe High Assurance (OV) certificates, or EV certificates.
  • Wildcard SSLs cover multiple subdomains. For example, you can secure *, which would cover,, and any other subdomains. You can purchase Wildcard SSLs as Standard or OV certificates.
  • Multiple Domain (UCC) SSLs can cover multiple subdomains, unique domain names, and websites. For example, you can secure,, and You can purchase UCC SSL’s as standard or EV certificates.

EV UCC SSLs represent all secondary domains with the primary business name, so all sites should be related. A UCC site seal displays only the primary domain name as “Issued To,” and all secondary websites are listed in the certificate details.

Where are you located?

Our SSL certificates are issued to individuals and companies worldwide, but there are a few restrictions. For more information, see Which countries are currently supported for certificate issuance?

Which type of server or Web hosting do you use?

Our SSL certificates work on all types of hosting and server configurations, but these specific servers must use the certificate listed:

  • Quick Shopping Cart® stores must use a single-domain Standard or Premium SSL.
  • Intel vPro servers must use an OV SSL.
  • Exchange Server 2007 and 2010 must use a UCC SSL to secure multiple services (domains).

All domains are listed in a UCC. If you want to secure both fully qualified (example: and partially qualified (example: domains with a UCC, make sure to select a domain for each one. Know which domains you need to cover when you purchase, because you cannot upgrade.

How to Secure the Right Domain for Your New Digital Business

Secure the Right Domain for Your New Digital Business – Every digital business starts with one thing in common: a domain name. Without a domain name, you do not have an address for your business where customers can find you.  It’s like having a business without having a physical address. How can you market that?

First, to secure the right domain for your new digital business, you need to know that not all domain names are created equal.  There are quite a few factors that you need to think about when securing the best domain name for your new digital business.

As a digital business broker, I have helped sell countless businesses and have seen firsthand the role that a domain name plays in the value of a business.

Whether you realize it, the domain name that you choose plays a critical role in how valuable your business will be — both while you own it, and for an investor should you ever decide to sell.

Here are 11 lessons that I’ve learned about what domain names mean to a business over the long haul.  Consider each of them when you’re securing the right domain name for your new digital business.

#1 – Secure the Right Domain for Your New Digital Business – Start early in the process.

If you have already named your business, you may not have started thinking about your domain name early enough.

It’s unfortunate, but many business owners register their business name, only to find out later that the domain name they wanted for their business has already been taken. You can try to get the registered owner to sell it, but often they want a crazy amount of money for it.

Some investors will monitor which businesses get registered and buy the related domain names as a “squatting” strategy. These domain brokers are known for controlling domains that business owners would typically want to use.

To avoid this hassle, you’ll want to make sure the domain is available before you register your business.  It will save you a ton of headaches (and money) down the road.

If the domain name you want isn’t available, it may be worth reconsidering your business name.  This can also help you avoid potential copyright issues that you couldn’t foresee before you started.

#2 – Secure the Right Domain for Your New Digital Business – Consider your branding.

If there’s one factor that billion-dollar digital businesses have in common, it’s that their domain name is easy to remember and it speaks directly to their branding.

Branding refers to the messaging that your company will use. The personality you’ll give the company, and the type of feeling that you want your customers to get when they think about your business.

Word of mouth and organic marketing are incredibly powerful. They only work if your visitors are able to get your domain name out of their mouth without having to explain how to spell it.

Once your business reaches the point where your customers are talking about your products and services, having a unique and memorable domain name will work hand-in-hand with your organic marketing.

#3 – Secure the Right Domain for Your New Digital Business – Remember, .com stands for commercial.

There’s nothing wrong with registering your business to extensions other than .com, as you’ll see in just a second. Even so, you do want to think about the fact that .com stands for commercial and refers to business domain names.

On top of that, most people inherently understand that a .com domain is the first type of domain they should visit when they’re looking for a business.

If someone mentions your business name to one of their friends or family, they are immediately going to assume that your website should be located at your business name with a .com extension.

Again, doesn’t mean you shouldn’t register other extensions, too, but the .com extension is currently one of the most important that you can register for your business.

Which brings me to my next point…

#4 – Secure the Right Domain for Your New Digital Business – Consider registering multiple extensions.

Just because a .com extension is the most important and most memorable, you shouldn’t necessarily neglect other extensions, either.

Other extensions, like .net, .org, and even some of the more boutique extensions, should all be considered. The goal for registering them should be to protect your brand and your business from potential squatters and scammers.

Scammers have duplicated a company’s website and rebuilt it on a separate extension. They then attempt to scam unsuspecting visitors into believing that they are indeed the actual company.

This can create a public relations nightmare for your business. On top of that, if someone does register a separate extension for your business you will need to go through the courts to have their domain name taken down.

Save yourself a headache. Once you have decided on the domain name you want, think about picking up other extensions that are available for it, too.

#5 – Secure the Right Domain for Your New Digital Business – Follow the domain name best practices.

When it comes to registering a domain name for your business, there are a few generally unspoken rules that you’ll need to follow.

The perfect domain name is going to support your business, but it will also:

● Be short and to the point.
● Contain minimum words that are easy to spell.
● Be unique and easy to remember.
● Be friendly to your SEO marketing campaign.
● Relevant to your business, products, or services.

It may not always be possible to find a domain name that fits into each of these criteria. Yet, this checklist is a good starting point for the different areas you want to address. It will help you get started brainstorming a list of potential domain names that you can register for your business.

#6 – Secure the Right Domain for Your New Digital Business – Think about search engine optimization.

I just touched on making sure that your domain name is friendly to your SEO marketing strategy. But let’s dive deeper into it — in case you’re unfamiliar with SEO.

If you’re starting a local-based business, it’s worth it to include your location in the domain name.

If you’re starting a nationwide business, think about the keywords that your visitors would type into the search engines if they were looking for your website.

Now, this tip comes with a bit of a caveat.  While you want to make sure you’re thinking about SEO when you buy your domain name, you do not want to start stuffing keywords into the domain name itself.

At a later date, you can create new pages on the website that have these keywords in them, if you want to stick primarily to registering the domain name as your business’ name.

#7 – Secure the Right Domain for Your New Digital Business – Register your name as the owner.

Some business owners will assign the task of buying the domain name and setting up the website to one of their employees.  What typically happens, though, is the employee will register the domain name into their own name, without thinking about the consequences.

If that employee leaves the business, you can no longer make edits to the domain name in the registrar without having them present or having them sign the domain name over to you.

If the domain name isn’t in your name, it isn’t actually yours.

If you are concerned about privacy, you can enable WHOIS privacy on most domain registrars, so that the information you used to register it with is not available to the public.

#8 – Secure the Right Domain for Your New Digital Business – Set up automatic renewal.

One problem among online business owners is forgetting to renew the domain name they’ve registered for their business.

While in most cases, this is only a small problem and can be remedied by logging into the registrar and clicking renew, in some cases it can be a huge issue.

Many domain name brokers and domainers will wait for business domain names to expire in an effort to quickly buy them up before the business owner realizes their mistake.  Once they own the domain name, the real problems begin.

These domainers will reach out and let the business owner know that it’s going to cost them to buy the domain name back. This fee can be anywhere from $1,000 to upwards of $10,000 or even $100,000 in the case of bigger businesses.

You can avoid this issue completely by simply turning on auto-renew and registering the domain name for 10 years at a time.  It’s a small price to pay upfront for long-term security.

#9 – Secure the Right Domain for Your New Digital Business – Don’t use dashes, hyphens, numbers, or abbreviations.

This tip is a mix of making sure your domain name is brandable and memorable. But this also ensures that it’s easy on your SEO campaign and even easier for your customers to spread the word about your business.

If your business has multiple words and that domain name is available, do not start adding hyphens.  On the same token, do not start adding numbers unless your business has numbers in the name.

You also want to avoid using abbreviated words because they do not translate well when someone is trying to say your domain name in a conversation.  People will attempt to type out the entire word instead of the abbreviation.

#10 – Secure the Right Domain for Your New Digital Business – Look into the domain’s past.

This tip covers you on two different bases — copyright infringement and SEO.

If you register a domain name, you could be infringing on another company’s copyrights without realizing you’re actually doing it.

To give you an example, I had a client wanting to sell a business.  He had owned the domain name for more than 3 years and decided it was time to sell.  Except, he couldn’t sell.

It was brought to my attention that the domain name he registered was actually the same name as a non-profit organization, and they chose not to register the domain name.  Upon realizing this, the client had to move his business to a new domain name and could no longer use the name he registered.

You also want to make sure that shady and blackhat SEOs haven’t used the domain name as part of a backlinking or scam operation.  If it has, it could be nearly impossible for you to rank in the organic search results.

#11 – Secure the Right Domain for Your New Digital Business – Don’t pay too much.

There are quite a few domain name registrars currently available.  Most of them are reasonably priced, but some will gouge domain names that they consider to be “premium”.

For a typical registrar, a .com domain name should cost between $7 and $15. This depends on what add-ons you get, whether they charge for privacy, and any other fees they may decide to add.

For some registrars, if their algorithm believes that the domain name you’re trying to register is “premium”, they could tell you that it will cost $1,000 or even more just to register it.

When that happens, you can go to another registrar and pick the same domain name and register it for between $7 to $15.  You want to avoid paying too much for the domain, especially if you’re going to register multiple extensions.

Secure the Right Domain for Your New Digital Business – Your Domain Name is Your Storefront.

Buying the domain name for your new business is critical because your domain name is literally your business’ address.  It’s the storefront where your customers are going to find you, and tell their friends and family members where to find you.

As long as you follow the 11 different tips I’ve given you here, coming to a decision on the domain you want to use in your business becomes significantly easier to do.

About Domain Names

Registering a domain name builds your credibility on the Internet. Use domain names to support your business and assist in creating a dynamic online presence. Your domain name establishes your online identity and increases branding, marketing and communication opportunities. Register multiple domain names to:

  • Keep your competition from registering a domain name that draws customers away from you.
  • Promote the products and services you offer.
  • Drive more traffic to your website.
  • Enjoy more opportunities to market to — and be listed on — search engines.
  • Create distinct advertising strategies to reach different target markets.
  • Provide customers more ways to find you on the Internet.
  • Capture common misspellings of your domain name, instead of sending visitors to an error page.
  • Protect your brand and online identity from unsavory parties.

To get started, check to see if the domain name you want is available. If available, register the domain name for a period of time you specify during the checkout process.

To Check a Domain Name’s Availability

  1. Go to our Home Page.
  2. In the Domain Name Search field, enter the domain name you want to register, and then select the domain name extension from the list.
  3. Click GO.

If the domain name you requested is already registered, we provide available alternatives. For example, you might be able to select a .info or .ws domain extension, rather than .com. Or you could register instead of

If the domain name is available, follow the instructions to complete the checkout process. Be sure to include valid contact information for each contact. The Internet Corporation for Assigned Names and Numbers (ICANN), the governing body for domain names, requires valid contact information (registrant, technical, billing, and administrative). If you enter false information, your domain name can be canceled.

Your contact information is public and accessible through the Whois database at most registrars. However, you can protect your privacy by registering your domain name with us using our private domain name registration services.

When you purchase private domain name registration, the Whois database lists the name of our privacy affiliate company, as well as their postal address and phone number – instead of your personal contact information.
