As of now, officials have asked health workers to spray antiseptics, leave drones to track the growth, and spray chemicals to contain the virus.

What is Chikungunya, and How Does It Spread?

Chikungunya is a viral disease which is usually transmitted by the infected Aedes mosquitoes, primarily Aedes aegypti and Aedes albopictus. According to experts, these mosquitoes bite during the daytime (early morning hours). Therefore, one should be aware of the signs and symptoms that they can cause, as a slight delay in treatment can also trigger severe health issues.

Signs and Symptoms of Chikungunya

How to know if you are infected by the chikungunya virus? Here are some of the warning signs and symptoms that you must look out for:

  1. High fever
  2. Debilitating joint pain
  3. Pinching headache
  4. Sore muscles
  5. Skin rash, and

Most of the patients recover within a week, but the pain in the joint may last months, and severe complications might appear in vulnerable groups of the population, such as infants and elderly patients.

China Battles Worst Chikungunya Outbreak: Is US at Risk Too?

As Chikungunya cases continue to rise across China, and with officials reintroducing COVID safety protocols to deal with the outbreak, people across the United States are worried that the virus could do the same in the US as well. Let's break down the data and understand the risk factors.

Mosquito Vectors

Chikungunya can be transmitted by Aedes mosquitoes, which occur in parts of the U.S., including California, where they already have an impact, transmitting dengue and Zika. Local chikungunya transmission did not happen in recent years; however, an increase in temperatures and expansion of cities is possible to make certain localities more conducive to the virus.

Urbanisation

The increasing temperature and urban development provide perfect conditions to enhance mosquito populations, so the probability of a local outbreak will be greater in the case of the arrival of an infected traveller.
