An outbreak of varicella Varicella zoster: This virus causes chickenpox and spreads easily among young children. The rash is typically widespread on the body and made up of small red spots that turn into itchy blisters The occurrence of chickenpox in pediatric hospitals disrupts routine care of immunologically normal patients and is potentially life-threatening to immunosuppressed patients.1 , 2 Guidelines for pr A positive history of varicella is generally considered as proof of immunity; serologic screening before vaccination of HCWs with a negative or uncertain history of varicella is likely to be cost effective. The extension of varicella outbreaks in the health care settings depends on how opportune the control measures are taken. COVID-19, a contagious infectious disease that threatens the health of the global population, is confirmed to spread via airborne transmission. Numerous other infectious diseases, such as influenza and chickenpox, are also transmitted to humans via respiratory droplets that people exhale.

Is varicella airborne
Airborne viruses, including measles, influenza, and coronavirus (COVID-19) are small enough to become suspended in the air when an infected person coughs or sneezes. Healthy people can breathe these infected air droplets and become sick.
The highly contagious nature of varicella-zoster virus (VZV) underlies the epidemics that Varicella is solely a human disease and is one of the most readily infectious illnesses. The virus can be spread by direct contact with fluid in the lesions or through the airborne spread from the respiratory tract. The attack rate among susceptible contacts in household settings is estimated at 65%-87%. Worldwide Distribution It is a bacterial or viral infection, but is also caused by an injury or fungal infection. Common symptoms include a persistent headache, fever, and skin rash.

Airborne transmission of varicella can occur. Answer: B. - Varicella is a notifiable disease in fewer states (less than 70%) than are measles, mumps, or rubella. This fact and the fact that many cases of varicella are mild and never come to medical attention contribute to the low rate of reporting of varicella to the CDC -- only 4%-6% of the estimated annual total of U.S. cases. Varicella is highly contagious. The virus can be spread from person to person by direct contact, inhalation of aerosols from vesicular fluid of skin lesions of acute varicella or zoster, and possibly through infected respiratory secretions that also may be aerosolized. Airborne spread of varicella has rarely been reported, but it may be a common mode of transmission in hospitals.
