Respiratory syncytial virus (RSV) is a common respiratory virus that can cause mild, cold-like symptoms in most people, but can lead to serious illness in infants, toddlers, and older adults.


Respiratory syncytial virus (RSV) is a highly contagious respiratory virus that infects the lungs and breathing passages. It is the most common cause of bronchiolitis, a serious respiratory illness that affects infants and young children. RSV is a member of the Pneumoviridae family, which includes other viruses such as human metapneumovirus (hMPV) and bovine respiratory syncytial virus (BRSV).


RSV spreads easily through the air when an infected person coughs or sneezes. It can also spread through contact with contaminated surfaces, such as toys or doorknobs. The virus can survive on surfaces for several hours, making it important to practice good hygiene to prevent the spread of RSV.

Respiratory syncytial virus (RSV) spreads easily through respiratory droplets released into the air when an infected person coughs or sneezes. These droplets can travel up to 3 feet and remain suspended in the air for several hours. When a healthy person inhales these droplets, the virus can enter their body and cause infection.

Direct contact with an infected person is another common mode of transmission. This can occur through touching an infected person’s nose, mouth, or eyes, or through contact with contaminated surfaces such as toys, doorknobs, or shared utensils. RSV can survive on surfaces for several hours, increasing the risk of transmission through indirect contact.

Infected individuals are most contagious during the first few days of illness, but they can continue to shed the virus for up to a week or more. This means that even people who seem to have recovered from RSV can still spread the virus to others.

Understanding the ways in which RSV spreads is crucial for effective prevention strategies. It highlights the importance of good hygiene practices, such as frequent handwashing, covering coughs and sneezes, and avoiding close contact with sick individuals, to minimize the risk of transmission.
