Measles: Bloodborne or Airborne?
Measles is one of the most contagious diseases globally, spreading through direct contact with infected people’s respiratory droplets, which are released into the air through coughing, sneezing, and other respiratory activities. So, airborne transmission is the primary mechanism of measles spread. It’s not bloodborne, which is fortunate, as it’s an efficient way to transmit many deadly viral diseases. Let’s break down the details on the contagiousness of measles:
Distinguishing Characteristics
Measles, a member of the paramyxoviridae family, has specific ways of spreading and infecting. Measles RUV (Rubiv-type virus) is not an easy virus to transmit because direct contact with mucus membranes is essential. While it’s contagious from as early as 4-7 days prior to the onset of symptoms (earliest stage called incubation period), people in quarantine can still spread it by interacting with others.
It takes multiple close contacts or brief intimate contact to be infectious: This means shaking hands with the infected person, sharing eating utensils or food, or spending considerable amounts of time in enclosed areas isn’t enough for the disease transmission.
Data Behind the Transmission
As revealed by the WHO’s case definition, "the probability that a susceptible person becomes infected after exposure within close proximity to an index case without public health measures is relatively low for measles." Research consistently show that the critical infectious exposure period spans:
- In young children (below 4 years): 9.9% (95% confidence interval CI: 7.6%-14.3%) exposure, infectious transmission rate = 43% within 3 days of contact
- In adult 14
- Sometimes, the transmission probability will slightly increase if we compare exposed individuals with those aged less, especially in case an immediate family member is not

Transmission Types: Modes & Duration
Airborne Transmission Methods:
Most relevant modes of airborne transmission associated with measles virus, mainly:
• Air borne transmission through inhalation. This is also sometimes denoted as "short distance
• Infectious microorganisms spread during sneezing, coughing,
and other respiratory movements where individuals shed
mucus carrying the virus through tiny droplet nucle2..
Importance of Vaccination in Prevention Strategies & Community Intervention for Controlling Infection Dynamics!
Given a measles outbreak, reintroducing vaccination programs will decrease this transmission rate.
While the measles transmission itself primarily occurs through airborne mode.
Key factors to consider, these actions will help keep society moving forward:
- Increased vaccination rates with more public awareness
will continue to help reduce infections globally & prevent any other contagious
diseases or public events from spreading their illness globally.
Evolution of Measles Strains
Historical records show changes, mainly in the genotypical or genotypic character
