Which month is dengue season?
The peak of the dengue epidemic period is around June to August during the rainy season. It is believed that climate is an important factor for dengue transmission.
When are mosquitoes most active in Singapore?
The Aedes mosquito is generally day-biting and most active during daylight hours, with peak biting at dawn (soon after sunrise) and dusk (just before sunset). However, in Singapore’s well-lit urban environment, the Aedes mosquito may also bite at night, as it could adapt to artificial lighting.
Is dengue virus seasonal?
Dengue incidence has been associated with variations in climate. Increased rainfall supports vector habitat availability, and high temperatures promote mosquito development. Dengue epidemics often occur seasonally, with more cases found during wetter and warmer months.
Is dengue all year-round?
Dengue, now a year-round disease, is an acute viral infection that affects mostly young children and infants.
Is dengue transmitted by kissing?
An infected mosquito can later transmit that virus to healthy people by biting them. Dengue cannot be spread directly from one person to another, and mosquitoes are necessary for transmission of the dengue virus.
Why is dengue so bad in Singapore?
The combination of people living in close proximity, the presence of Aedes mosquitoes and the availability of artificial breeding receptacles such as pails and potted plants has led to the greater concentration of dengue clusters in the east, it added.
Is one mosquito bite enough for dengue?
Importantly, one mosquito bite is sufficient enough to transmit the dengue virus and make you sick for days.
Can you be immune to dengue?
Recovery from infection by one dengue virus provides lifelong immunity against that particular virus serotype. However, this immunity confers only partial and transient protection against subsequent infection by the other three serotypes of the virus.
How long does dengue immunity last?
After recovering from a first dengue infection, a person is protected from infection with the remaining three dengue serotypes for two to three months. Unfortunately, it is not long-term protection, and after that short period, a person can be infected with any of the remaining three dengue serotypes.
What happens if you get dengue 3 times?
“There are four different serotypes (which can be understood as “types”) of dengue. So, if you were to get infected by the first serotype, it is equally possible for you to get infected by the second, third and fourth. It’s just that you will be immune for life against the first serotype.”
