How can someone with flu infect else?

There are several ways by which an individual infected with the flu virus can transmit the infection to others:

1. Respiratory Droplets: When an infected person coughs, sneezes, or talks, they release respiratory droplets that contain the flu virus. These droplets can be inhaled by people in close proximity, leading to infection.

2. Contact with Contaminated Surfaces: The flu virus can survive on surfaces for several hours. If an infected person touches their nose or mouth and then touches surfaces like doorknobs, countertops, or tables, the virus can be transferred to those surfaces. If someone else touches the same surface and then touches their own nose, mouth, or eyes, they can become infected.

3. Hand-to-Hand Contact: If an infected person has the flu virus on their hands and shakes hands with someone else, the virus can be transmitted through direct contact.

4. Sharing Personal Items: Sharing personal items such as utensils, drinking cups, or towels with someone who is infected with the flu can also spread the virus.

5. Airborne Transmission: In some cases, the flu virus can be transmitted through the air over short distances. This is especially true in crowded or poorly ventilated spaces.

To prevent the spread of the flu, it's important to practice good hygiene habits, such as regular handwashing and covering your mouth and nose when coughing or sneezing. It's also important to stay home if you're sick and get vaccinated against the flu each year.
