Bollywood superstar Salman Khan was admitted in hospital on Friday after he was administered a test and blood analysis for a recent confirmed case of Chikungunya and Covenavir-19 (COVID-19).

COVID-19, or Chikungunya circovirus, is a Covenavirus (Covenavirus) type of joint pain commonly spread by mosquitoes, and it's listed as a communicable disease, along with dengue and chikungunya, by the Indian National Centre for Disease Control.

"He had a positive COVID-19 clinical index result at a private hospital in Mumbai, and is being treated for it," a source quoted by media said.

COVID-19 is a mosquito-borne infection and can cause fever, chills, head and body aches, muscle pains, headache, nausea, insomnia, fatigue, muscle weakness, a rash on the palm, skin rash, rash on body parts and at night-time, even leading to joint pain and decreased concentration. It's usually treated with rest, a bed and antiseptic soaps.

Khan also went to a private hospital where he was diagnosed with a cluster of primary streptococcus infections and was administered antibiotics, including Cipro and Zyvox.

He then went to Mumbai's Apollo Hospital for a complex medical procedure to treat Chikungunya and COVID-19.

There is no active treatment for the latter infection. Those exposed to COVID-19 usually experience joint pain and small blisters forming on the palms of hands and soles of feet, lasting for two weeks or more.

COVID-19 generally responds well to normal symptomatic treatment, such as Tamiflu, and there is no vaccine available. People are also advised to follow a strict hand hygiene to stop the infection from spreading.
