Recently, reports of chikungunya fever cases in Guangdong and other areas have drawn widespread attention. With the summer's high temperatures, heavy rainfall, and active mosquitoes, this mosquito-borne infectious disease does require attention, but there is no need for panic. Through scientific understanding and effective prevention, we can significantly reduce the risk of infection.

I: Chikungunya Fever: The Overlooked "Joint Pain Fever"

chikungunya fever (CHIKF) is an acute infectious disease caused by the chikungunya virus, primarily transmitted through the bite of Aedes albopictus (Asian tiger mosquito) and Aedes aegypti (yellow fever mosquito). The incubation period is generally 3-7 days. Its name originates from the African indigenous language "Chikungunya," meaning "to become contorted," vividly describing the typical manifestation of patients experiencing severe joint pain that hinders movement. Although the mortality rate is very low, large-scale outbreaks and epidemics are prone to occur in areas with high mosquito density. Patients and those with asymptomatic infections are the main sources of infection. Non-human primates are hosts of this disease. The general population is susceptible to the chikungunya virus, and humans who are infected develop lasting immunity.

II: Be Wary of the "Fever-Joint Pain-Rash" Triad

1. Typical Symptoms High fever: Sudden onset of high fever (39-40℃), with about 50% of patients exhibiting "double-peak fever" (fever subsides for 1-3 days, then recurs).

Joint symptoms: Often affects small joints such as fingers, wrists, and ankles; symmetrical pain with morning stiffness; about 20% of patients experience pain for several months (chronic arthritis).

Rash: A red maculopapular rash appears 2-5 days after the onset of illness, mostly on the face and limbs.

2. Accompanying Symptoms Nausea, vomiting, headache, conjunctival hyperemia, etc.; severe cases may experience bleeding or neurological complications (<1%). 【Important Distinction】: Compared to dengue fever, chikungunya fever has more severe and persistent joint pain, but less bleeding tendency. Confirmation requires laboratory testing (PCR or antibody testing) to avoid misdiagnosis and delay in treatment. Early prevention and avoiding mosquito bites are key to dealing with chikungunya fever.

III: Four Products, Each with a Specific Role in Protecting Health

IV: Prevention Strategies: Breaking the Mosquito-borne Transmission Chain

1. Home Protection "Three Cleanings" Clear standing water: Check and invert flower pot trays, discarded containers, tires, and other water-containing objects weekly. Clear dead corners: Clear balcony drains and air conditioner drain pipes to ensure no wastewater remains. Clear clutter: Organize yard debris to reduce mosquito hiding spaces.

2. Personal Protection "Three Essentials" Clothing: Wear light-colored long-sleeved shirts and pants when going out to avoid skin exposure. Mosquito Repellent: Use mosquito repellent sprays containing DEET or picaridin, reapplying every 4 hours. Peak Avoidance: Avoid going out during peak mosquito activity hours in the morning (6-9 am) and evening (4-7 pm).

Currently, there are no specific drugs or vaccines.
The core of prevention lies in "mosquito prevention + mosquito elimination".
