Can Dengue Spread In A Household? Here's What You Need To Know

As dengue cases continue to rise in India, one common concern is whether dengue can spread within a household if one person becomes infected.

Dengue is primarily transmitted through the Aedes mosquito, which becomes infected when it bites a person with dengue and subsequently spreads the virus to other individuals through subsequent bites [1].

However, it is essential to note that dengue is not directly contagious from person to person, unlike the common cold or flu.

Factors Influencing Dengue Transmission

While dengue does not spread directly from person to person, certain factors within a household can contribute to its transmission:

  • Proximity: Close contact with an infected individual increases the risk of mosquito bites, amplifying the chances of dengue transmission within a household.
  • Shared spaces: If an infected person shares a living space with others, such as a bedroom or living room, the presence of mosquitoes increases the likelihood of transmission.
  • Mosquito breeding sites: Stagnant water sources, like flower pots, water containers, or discarded items, can contribute to an increased mosquito population, further elevating the risk of dengue transmission.

How Dengue Transmission Can Happen Within A Household

To illustrate the potential spread of dengue within a household, let us consider a few scenarios:

  • A family member contracts dengue during a trip to a dengue-endemic area. Upon returning home, if there are mosquitoes present in the household, they may become infected and transmit the virus to other family members.
  • An infected household member is bitten by a mosquito, which then bites another family member, facilitating dengue transmission within the household.

Preventive Measures To Prevent The Spread Of Dengue

To reduce the risk of dengue transmission within a household, it is crucial to adopt preventive measures:

  • Eliminate mosquito breeding sites by regularly emptying and cleaning water containers, ensuring there are no areas of stagnant water.
  • Use mosquito repellents or protective clothing to reduce mosquito bites.
  • Install window screens or use bed nets to create a physical barrier against mosquitoes.
  • Encourage the use of insecticide-treated mosquito nets, especially for children and pregnant women.
