lungs. So in case, the patient contracts severe infections, the walls and linings of the air sacs in the lungs are affected. Symptoms: Excessive sputum production, coughing, chest congestion and difficulty in breathing.
COVID can cause acute coronary syndrome, congestive heart failure, myocarditis, and arrhythmias. A study has pointed out, "Systemic inflammatory responses such as cytokine storms can cause myocarditis without direct viral infiltration.
It can cause heart failure and arrhythmias. This can occur even after the acute phase of the infection has resolved and in the absence of lung damage." So people who already have heart issues should remain cautious as COVID can worsen the condition. Symptoms: Tightness in the chest, cold sweat, breathing issues, irregular heartbeat, and discomfort in the arms, neck and jaw.
COVID can affect the brain in many ways. Its receptor cells are present in the cerebral cortex and brainstem, which facilitates the entrance of the virus.
