Arnold Clavio tests 'positive' a day after he was tested 'negative'

Popular Kapuso broadcaster Arnold Clavio said he was surprised to find out he was tested positive for COVID-19 just one day after he was tested negative for the same virus.
On Instagram, Arnold said that it was the first time he was infected with the virus.
His full post on Instagram:
"After almost two years, this is my first time to be infected by Covid19 virus... It’s real and serious... Although may mild symptoms ako, like cough due to hyperacidity, last Thursday may close contact ako sa isang nag-positive... Immediately I had my antigen test done, and it turned out ‘negative’...
"Yesterday, after this rtpcr test, the result was ‘negative’... This morning, para makasiguro, I had my antigen test again and bad news - I am ‘positive’... And the only way to fight this virus is a positive thought... Sa kabila ng pag-iingat ko, wearing of mask, hand washing, social distancing, vitamins, immune booster, lots of vitamin D, tinamaan pa rin ako and I don’t know how... So be careful everyone... See you in after 7 - 14 days of isolation... God is good! Amen."
In a separate post, Igan thanked his fans for their prayers and support.
"Goodnight everyone. Thank you for all your prayers. Di ko ito malalagpasan, kung wala kayong lahat. At promise, magpapalakas ako para sa inyo.
"We will heal as one. Prayers also sa mga nakakaranas ng pagsubok katulad sa akin. Trust in the Lord and we’ll be triumphant. Amen!!!"
