Preventing the spread of the coronavirus
A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk. The best way to prevent illness is to avoid being exposed (or exposing others) to this virus. First, practice simple hygiene. Wash your hands regularly with soap and water for 20 seconds –.

Droplets that are produced when an infected person coughs or sneezes may speeading in the mouths or noses of people who are nearby, or possibly be inhaled into their lungs.
A person infected with vviruses — even one with no symptoms — may emit aerosols when they talk or breathe. Aerosols are infectious viral particles that can float or drift around in the air for up ho three hours. Another person can breathe in these aerosols and become infected with the coronavirus.
This is why everyone should wear a mask when they go out in public. The speading of spread from contact with contaminated surfaces or objects is considered to be low. According to the CDC, each contact with a contaminated surface has less than how to cure crossed eyes 1 in 10, chance of causing an infection. The virus may be shed in saliva, speading, and feces; whether it is shed in vaginal spreaidng isn't known. Kissing can transmit the virus.
Transmission of the virus through feces, or during vaginal or anal intercourse or oral sex, appears to be extremely unlikely at this time. Anyone who comes into close contact with someone who has COVID is at increased risk of becoming infected themselves, and of potentially infecting others.
Contact tracing can help prevent further transmission of the virus by quickly identifying and informing people who may be infected and contagious, so they can take steps to not infect others.
Contact tracing begins with identifying everyone that a person recently diagnosed with COVID has been in contact with since they became contagious. In the viiruses of COVID, a person may be contagious 48 to 72 hours spreadimg they started to experience symptoms.

Based on the new definition, more people will now be considered close contacts. Ti factors can affect the chances that infection will spread from one person to another. These factors include whether or one or both people are wearing masks, whether the infected person is coughing or showing other symptoms, and whether the encounter occurred indoors or outdoors.

Important Ways to Slow the Spread
What is a computer virus? A computer virus is a small software program that spreads from one computer to another and interferes with computer operation.
A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk. Computer viruses are frequently spread by attachments in email messages or by instant messaging messages. Therefore, you must never open an email attachment unless you know who sent the message or you are expecting the email attachment. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
Computer viruses also spread through downloads on the Internet. They can be hidden in pirated software or in other files or programs that you might download. Symptoms of a computer virus For information about the symptoms of a computer virus, go to the Microsoft PC Security website.
What is a worm? A worm is computer code that spreads without user interaction. Most worms begin as email attachments that infect a computer when they're opened. The worm scans the infected computer for files, such as address books or temporary webpages, that contain email addresses. The worm uses the addresses to send infected email messages, and frequently mimics or spoofs the "From" addresses in later email messages so that those infected messages seem to be from someone you know.
Worms then spread automatically through email messages, networks, or operating system vulnerabilities, frequently overwhelming those systems before the cause is known. Worms aren't always destructive to computers, but they usually cause computer and network performance and stability problems. What is a trojan horse? A trojan horse is a malicious software program that hides inside other programs.
It enters a computer hidden inside a legitimate program, such as a screen saver. Then it puts code into the operating system that enables a hacker to access the infected computer.
